-
-`v0.21.0` is a major feature release.
-
-## Features in this release
-
-1. **Better error messages with condition chaining**
-
-   In v0.18, we added better error messages that could tell you what problem happened,
-   but they couldn't tell you *why* it happened. `0.21` adds *condition chaining* to the
-   solver, and Spack can now trace back through the conditions that led to an error and
-   build a tree of causes potential causes and where they came from. For example:
-
-   ```console
-   $ spack solve hdf5 ^cmake@3.0.1
-   ==> Error: concretization failed for the following reasons:
-
-      1. Cannot satisfy 'cmake@3.0.1'
-      2. Cannot satisfy 'cmake@3.0.1'
-           required because hdf5 ^cmake@3.0.1 requested from CLI
-      3. Cannot satisfy 'cmake@3.18:' and 'cmake@3.0.1
-           required because hdf5 ^cmake@3.0.1 requested from CLI
-           required because hdf5 depends on cmake@3.18: when @1.13:
-             required because hdf5 ^cmake@3.0.1 requested from CLI
-      4. Cannot satisfy 'cmake@3.12:' and 'cmake@3.0.1
-           required because hdf5 depends on cmake@3.12:
-             required because hdf5 ^cmake@3.0.1 requested from CLI
-           required because hdf5 ^cmake@3.0.1 requested from CLI
-   ```
-
-   More details in #40173.
-
-2. **OCI build caches**
-
-   You can now use an arbitrary [OCI](https://opencontainers.org) registry as a build
-   cache:
-
-   ```console
-   $ spack mirror add my_registry oci://user/image # Dockerhub
-   $ spack mirror add my_registry oci://ghcr.io/haampie/spack-test # GHCR
-   $ spack mirror set --push --oci-username ... --oci-password ... my_registry  # set login creds
-   $ spack buildcache push my_registry [specs...]
-   ```
-
-   And you can optionally add a base image to get *runnable* images:
-
-   ```console
-   $ spack buildcache push --base-image ubuntu:23.04 my_registry python
-   Pushed ... as [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack
-
-   $ docker run --rm -it [image]:python-3.11.2-65txfcpqbmpawclvtasuog4yzmxwaoia.spack
-   ```
-
-   This creates a container image from the Spack installations on the host system,
-   without the need to run `spack install` from a `Dockerfile` or `sif` file. It also
-   addresses the inconvenience of losing binaries of dependencies when `RUN spack
-   install` fails inside `docker build`.
-
-   Further, the container image layers and build cache tarballs are the same files. This
-   means that `spack install` and `docker pull` use the exact same underlying binaries.
-   If you previously used `spack install` inside of `docker build`, this feature helps
-   you save storage by a factor two.
-
-   More details in #38358.
-
-3. **Multiple versions of build dependencies**
-
-   Increasingly, complex package builds require multiple versions of some build
-   dependencies. For example, Python packages frequently require very specific versions
-   of `setuptools`, `cython`, and sometimes different physics packages require different
-   versions of Python to build. The concretizer enforced that every solve was *unified*,
-   i.e., that there only be one version of every package. The concretizer now supports
-   "duplicate" nodes for *build dependencies*, but enforces unification through
-   transitive link and run dependencies. This will allow it to better resolve complex
-   dependency graphs in ecosystems like Python, and it also gets us very close to
-   modeling compilers as proper dependencies.
-
-   This change required a major overhaul of the concretizer, as well as a number of
-   performance optimizations. See #38447, #39621.
-
-4. **Cherry-picking virtual dependencies**
-
-   You can now select only a subset of virtual dependencies from a spec that may provide
-   more. For example, if you want `mpich` to be your `mpi` provider, you can be explicit
-   by writing:
-
-   ```
-   hdf5 ^[virtuals=mpi] mpich
-   ```
-
-   Or, if you want to use, e.g., `intel-parallel-studio` for `blas` along with an external
-   `lapack` like `openblas`, you could write:
-
-   ```
-   strumpack ^[virtuals=mpi] intel-parallel-studio+mkl ^[virtuals=lapack] openblas
-   ```
-
-   The `virtuals=mpi` is an edge attribute, and dependency edges in Spack graphs now
-   track which virtuals they satisfied. More details in #17229 and #35322.
-
-   Note for packaging: in Spack 0.21 `spec.satisfies("^virtual")` is true if and only if
-   the package specifies `depends_on("virtual")`. This is different from Spack 0.20,
-   where depending on a provider implied depending on the virtual provided. See #41002
-   for an example where `^mkl` was being used to test for several `mkl` providers in a
-   package that did not depend on `mkl`.
-
-5. **License directive**
-
-   Spack packages can now have license metadata, with the new `license()` directive:
-
-   ```python
-       license("Apache-2.0")
-   ```
-
-   Licenses use [SPDX identifiers](https://spdx.org/licenses), and you can use SPDX
-   expressions to combine them:
-
-   ```python
-       license("Apache-2.0 OR MIT")
-   ```
-
-   Like other directives in Spack, it's conditional, so you can handle complex cases like
-   Spack itself:
-
-   ```python
-      license("LGPL-2.1", when="@:0.11")
-      license("Apache-2.0 OR MIT", when="@0.12:")
-   ```
-
-   More details in #39346, #40598.
-
-6. **`spack deconcretize` command**
-
-   We are getting close to having a `spack update` command for environments, but we're
-   not quite there yet. This is the next best thing. `spack deconcretize` gives you
-   control over what you want to update in an already concrete environment. If you have
-   an environment built with, say, `meson`, and you want to update your `meson` version,
-   you can run:
-
-   ```console
-   spack deconcretize meson
-   ```
-
-   and have everything that depends on `meson` rebuilt the next time you run `spack
-   concretize`. In a future Spack version, we'll handle all of this in a single command,
-   but for now you can use this to drop bits of your lockfile and resolve your
-   dependencies again. More in #38803.
-
-7. **UI Improvements**
-
-   The venerable `spack info` command was looking shabby compared to the rest of Spack's
-   UI, so we reworked it to have a bit more flair. `spack info` now makes much better
-   use of terminal space and shows variants, their values, and their descriptions much
-   more clearly. Conditional variants are grouped separately so you can more easily
-   understand how packages are structured. More in #40998.
-
-   `spack checksum` now allows you to filter versions from your editor, or by version
-   range. It also notifies you about potential download URL changes. See #40403.
-
-8. **Environments can include definitions**
-
-   Spack did not previously support using `include:` with The
-   [definitions](https://spack.readthedocs.io/en/latest/environments.html#spec-list-references)
-   section of an environment, but now it does. You can use this to curate lists of specs
-   and more easily reuse them across environments. See #33960.
-
-9. **Aliases**
-
-   You can now add aliases to Spack commands in `config.yaml`, e.g. this might enshrine
-   your favorite args to `spack find` as `spack f`:
-
-   ```yaml
-   config:
-     aliases:
-       f: find -lv
-   ```
-
-   See #17229.
-
-10. **Improved autoloading of modules**
-
-    Spack 0.20 was the first release to enable autoloading of direct dependencies in
-    module files.
-
-    The downside of this was that `module avail` and `module load` tab completion would
-    show users too many modules to choose from, and many users disabled generating
-    modules for dependencies through `exclude_implicits: true`. Further, it was
-    necessary to keep hashes in module names to avoid file name clashes.
-
-    In this release, you can start using `hide_implicits: true` instead, which exposes
-    only explicitly installed packages to the user, while still autoloading
-    dependencies. On top of that, you can safely use `hash_length: 0`, as this config
-    now only applies to the modules exposed to the user -- you don't have to worry about
-    file name clashes for hidden dependencies.
-
-   Note: for `tcl` this feature requires Modules 4.7 or higher
-
-11. **Updated container labeling**
-
-    Nightly Docker images from the `develop` branch will now be tagged as `:develop` and
-    `:nightly`. The `:latest` tag is no longer associated with `:develop`, but with the
-    latest stable release. Releases will be tagged with `:{major}`, `:{major}.{minor}`
-    and `:{major}.{minor}.{patch}`. `ubuntu:18.04` has also been removed from the list of
-    generated Docker images, as it is no longer supported. See #40593.
-
-## Other new commands and directives
-
-* `spack env activate` without arguments now loads a `default` environment that you do
-  not have to create (#40756).
-* `spack find -H` / `--hashes`: a new shortcut for piping `spack find` output to

-title: "The Spack Package Manager: Bringing Order to HPC Software Chaos"
-abstract: >-
-  Large HPC centers spend considerable time supporting software for thousands of users, but the
-  complexity of HPC software is quickly outpacing the capabilities of existing software management
-  tools. Scientific applications require specific versions of compilers, MPI, and other dependency
-  libraries, so using a single, standard software stack is infeasible. However, managing many
-  configurations is difficult because the configuration space is combinatorial in size. We
-  introduce Spack, a tool used at Lawrence Livermore National Laboratory to manage this complexity.
-  Spack provides a novel, re- cursive specification syntax to invoke parametric builds of packages
-  and dependencies. It allows any number of builds to coexist on the same system, and it ensures
-  that installed packages can find their dependencies, regardless of the environment. We show
-  through real-world use cases that Spack supports diverse and demanding applications, bringing
-  order to HPC software chaos.

 Spack is a multi-platform package manager that builds and installs
 multiple versions and configurations of software. It works on Linux,
-macOS, Windows, and many supercomputers. Spack is non-destructive: installing a
+macOS, and many supercomputers. Spack is non-destructive: installing a
 new version of a package does not break existing installations, so many
 configurations of the same package can coexist.

-Python packages and virtual environments
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Spack can install a large number of Python packages. Their names are
-typically prefixed with ``py-``. Installing and using them is no
-different from any other package:
-
-.. code-block:: console
-
-   $ spack install py-numpy
-   $ spack load py-numpy
-   $ python3
-   >>> import numpy
-
-The ``spack load`` command sets the ``PATH`` variable so that the right Python
-executable is used, and makes sure that ``numpy`` and its dependencies can be
-located in the ``PYTHONPATH``.
-
-Spack is different from other Python package managers in that it installs
-every package into its *own* prefix. This is in contrast to ``pip``, which
-installs all packages into the same prefix, be it in a virtual environment
-or not.
-
-For many users, **virtual environments** are more convenient than repeated
-``spack load`` commands, particularly when working with multiple Python
-packages. Fortunately Spack supports environments itself, which together
-with a view are no different from Python virtual environments.
-
-The recommended way of working with Python extensions such as ``py-numpy``
-is through :ref:`Environments <environments>`. The following example creates
-a Spack environment with ``numpy`` in the current working directory. It also
-puts a filesystem view in ``./view``, which is a more traditional combined
-prefix for all packages in the environment.
-
-.. code-block:: console
-
-   $ spack env create --with-view view --dir .
-   $ spack -e . add py-numpy
-   $ spack -e . concretize
-   $ spack -e . install
-
-Now you can activate the environment and start using the packages:
-
-.. code-block:: console
-
-   $ spack env activate .
-   $ python3
-   >>> import numpy
-
-The environment view is also a virtual environment, which is useful if you are
-sharing the environment with others who are unfamiliar with Spack. They can
-either use the Python executable directly:
-
-.. code-block:: console
-
-   $ ./view/bin/python3
-   >>> import numpy
-
-or use the activation script:
-
-.. code-block:: console
-
-   $ source ./view/bin/activate
-   $ python3
-   >>> import numpy
-
-In general, there should not be much difference between ``spack env activate``
-and using the virtual environment. The main advantage of ``spack env activate``
-is that it knows about more packages than just Python packages, and it may set
-additional runtime variables that are not covered by the virtual environment
-activation script.

+---------------------------
+Extensions & Python support
+---------------------------
+
+Spack's installation model assumes that each package will live in its
+own install prefix.  However, certain packages are typically installed
+*within* the directory hierarchy of other packages.  For example,
+`Python <https://www.python.org>`_ packages are typically installed in the
+``$prefix/lib/python-2.7/site-packages`` directory.
+
+In Spack, installation prefixes are immutable, so this type of installation
+is not directly supported. However, it is possible to create views that
+allow you to merge install prefixes of multiple packages into a single new prefix.
+Views are a convenient way to get a more traditional filesystem structure.
+Using *extensions*, you can ensure that Python packages always share the
+same prefix in the view as Python itself. Suppose you have
+Python installed like so:

+
+The extensions are a subset of what's returned by ``spack list``, and
+they are packages like any other.  They are installed into their own
+prefixes, and you can see this with ``spack find --paths``:
+
+.. code-block:: console

+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Using Extensions in Environments
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The recommended way of working with extensions such as ``py-numpy``
+above is through :ref:`Environments <environments>`. For example,
+the following creates an environment in the current working directory
+with a filesystem view in the ``./view`` directory:
+
+.. code-block:: console
+
+   $ spack env create --with-view view --dir .
+   $ spack -e . add py-numpy
+   $ spack -e . concretize
+   $ spack -e . install
+
+We recommend environments for two reasons. Firstly, environments
+can be activated (requires :ref:`shell-support`):
+
+.. code-block:: console
+
+   $ spack env activate .
+
+which sets all the right environment variables such as ``PATH`` and
+``PYTHONPATH``. This ensures that
+
+.. code-block:: console
+
+   $ python
+   >>> import numpy
+
+works. Secondly, even without shell support, the view ensures
+that Python can locate its extensions:
+
+.. code-block:: console
+
+   $ ./view/bin/python
+   >>> import numpy
+
+See :ref:`environments` for a more in-depth description of Spack
+environments and customizations to views.
+
+^^^^^^^^^^^^^^^^^^^^
+Using ``spack load``
+^^^^^^^^^^^^^^^^^^^^
+
+A more traditional way of using Spack and extensions is ``spack load``
+(requires :ref:`shell-support`). This will add the extension to ``PYTHONPATH``
+in your current shell, and Python itself will be available in the ``PATH``:
+
+.. code-block:: console
+
+   $ spack load py-numpy
+   $ python
+   >>> import numpy
+
+The loaded packages can be checked using ``spack find --loaded``
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Loading Extensions via Modules
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Apart from ``spack env activate`` and ``spack load``, you can load numpy
+through your environment modules (using ``environment-modules`` or
+``lmod``). This will also add the extension to the ``PYTHONPATH`` in
+your current shell.
+
+.. code-block:: console
+
+   $ module load <name of numpy module>
+
+If you do not know the name of the specific numpy module you wish to
+load, you can use the ``spack module tcl|lmod loads`` command to get
+the name of the module from the Spack spec.

--------------------
-Build cache signing
--------------------
-
-By default, Spack will add a cryptographic signature to each package pushed to
-a build cache, and verifies the signature when installing from a build cache.
-
-Keys for signing can be managed with the :ref:`spack gpg <cmd-spack-gpg>` command,
-as well as ``spack buildcache keys`` as mentioned above.
-
-You can disable signing when pushing with ``spack buildcache push --unsigned``,
-and disable verification when installing from any build cache with
-``spack install --no-check-signature``.
-
-Alternatively, signing and verification can be enabled or disabled on a per build cache
-basis:
-
-.. code-block:: console
-
-    $ spack mirror add --signed <name> <url>  # enable signing and verification
-    $ spack mirror add --unsigned <name> <url>  # disable signing and verification
-
-    $ spack mirror set --signed <name>  # enable signing and verification for an existing mirror
-    $ spack mirror set --unsigned <name>  # disable signing and verification for an existing mirror
-
-Or you can directly edit the ``mirrors.yaml`` configuration file:
-
-.. code-block:: yaml
-
-    mirrors:
-      <name>:
-        url: <url>
-        signed: false # disable signing and verification
-
-See also :ref:`mirrors`.
 
 ----------
 Relocation
 ----------
 
-When using buildcaches across different machines, it is likely that the install
-root will be different from the one used to build the binaries.
-
-To address this issue, Spack automatically relocates all paths encoded in binaries
-and scripts to their new location upon install.
-
-Note that there are some cases where this is not possible: if binaries are built in
-a relatively short path, and then installed to a longer path, there may not be enough
-space in the binary to encode the new path. In this case, Spack will fail to install
-the package from the build cache, and a source build is required.
-
-To reduce the likelihood of this happening, it is highly recommended to add padding to
-the install root during the build, as specified in the :ref:`config <config-yaml>`
-section of the configuration:
-
-.. code-block:: yaml
-
-   config:
-     install_tree:
-       root: /opt/spack
-       padded_length: 128
-
-
-.. _binary_caches_oci:
-
----------------------------------
-Automatic push to a build cache
----------------------------------
-
-Sometimes it is convenient to push packages to a build cache as soon as they are installed. Spack can do this by setting autopush flag when adding a mirror:
-
-.. code-block:: console
-
-    $ spack mirror add --autopush <name> <url or path>
-
-Or the autopush flag can be set for an existing mirror:
-
-.. code-block:: console
-
-    $ spack mirror set --autopush <name>  # enable automatic push for an existing mirror
-    $ spack mirror set --no-autopush <name>  # disable automatic push for an existing mirror
-
-Then after installing a package it is automatically pushed to all mirrors with ``autopush: true``. The command
-
-.. code-block:: console
-
-    $ spack install <package>
-
-will have the same effect as
-
-.. code-block:: console
-
-    $ spack install <package>
-    $ spack buildcache push <cache> <package>  # for all caches with autopush: true
-
-.. note::
-
-    Packages are automatically pushed to a build cache only if they are built from source.
-
------------------------------------------
-OCI / Docker V2 registries as build cache
------------------------------------------
-
-Spack can also use OCI or Docker V2 registries such as Dockerhub, Quay.io,
-Github Packages, GitLab Container Registry, JFrog Artifactory, and others
-as build caches. This is a convenient way to share binaries using public
-infrastructure, or to cache Spack built binaries in Github Actions and
-GitLab CI.
-
-To get started, configure an OCI mirror using ``oci://`` as the scheme,
-and optionally specify a username and password (or personal access token):
-
-.. code-block:: console
-
-    $ spack mirror add --oci-username username --oci-password password my_registry oci://example.com/my_image
-
-Spack follows the naming conventions of Docker, with Dockerhub as the default
-registry. To use Dockerhub, you can omit the registry domain:
-
-.. code-block:: console
-
-    $ spack mirror add --oci-username username --oci-password password my_registry oci://username/my_image
-
-From here, you can use the mirror as any other build cache:
-
-.. code-block:: console
-
-    $ spack buildcache push my_registry <specs...>  # push to the registry
-    $ spack install <specs...> # install from the registry
-
-A unique feature of buildcaches on top of OCI registries is that it's incredibly
-easy to generate get a runnable container image with the binaries installed. This
-is a great way to make applications available to users without requiring them to
-install Spack -- all you need is Docker, Podman or any other OCI-compatible container
-runtime.
-
-To produce container images, all you need to do is add the ``--base-image`` flag
-when pushing to the build cache:
-
-.. code-block:: console
-
-    $ spack buildcache push --base-image ubuntu:20.04 my_registry ninja
-    Pushed to example.com/my_image:ninja-1.11.1-yxferyhmrjkosgta5ei6b4lqf6bxbscz.spack
-
-    $ docker run -it example.com/my_image:ninja-1.11.1-yxferyhmrjkosgta5ei6b4lqf6bxbscz.spack
-    root@e4c2b6f6b3f4:/# ninja --version
-    1.11.1
-
-If ``--base-image`` is not specified, distroless images are produced. In practice,
-you won't be able to run these as containers, since they don't come with libc and
-other system dependencies. However, they are still compatible with tools like
-``skopeo``, ``podman``, and ``docker`` for pulling and pushing.
-
-.. note::
-    The docker ``overlayfs2`` storage driver is limited to 128 layers, above which a
-    ``max depth exceeded`` error may be produced when pulling the image. There
-    are `alternative drivers <https://docs.docker.com/storage/storagedriver/>`_.
-
-------------------------------------
-Spack build cache for GitHub Actions
-------------------------------------
-
-To significantly speed up Spack in GitHub Actions, binaries can be cached in
-GitHub Packages. This service is an OCI registry that can be linked to a GitHub
-repository.
-
-Spack offers a public build cache for GitHub Actions with a set of common packages,
-which lets you get started quickly. See the following resources for more information:
-
-* `spack/setup-spack <https://github.com/spack/setup-spack>`_ for setting up Spack in GitHub
-  Actions
-* `spack/github-actions-buildcache <https://github.com/spack/github-actions-buildcache>`_ for
-  more details on the public build cache
+Initial build and later installation do not necessarily happen at the same
+location. Spack provides a relocation capability and corrects for RPATHs and
+non-relocatable scripts. However, many packages compile paths into binary
+artifacts directly. In such cases, the build instructions of this package would
+need to be adjusted for better re-locatability.

+Package Settings (packages.yaml)
+================================
+
+Spack allows you to customize how your software is built through the
+``packages.yaml`` file.  Using it, you can make Spack prefer particular
+implementations of virtual dependencies (e.g., MPI or BLAS/LAPACK),
+or you can make it prefer to build with particular compilers.  You can
+also tell Spack to use *external* software installations already
+present on your system.
+
+At a high level, the ``packages.yaml`` file is structured like this:
+
+.. code-block:: yaml
+
+   packages:
+     package1:
+       # settings for package1
+     package2:
+       # settings for package2
+     # ...
+     all:
+       # settings that apply to all packages.
+
+So you can either set build preferences specifically for *one* package,
+or you can specify that certain settings should apply to *all* packages.
+The types of settings you can customize are described in detail below.
+
+Spack's build defaults are in the default
+``etc/spack/defaults/packages.yaml`` file.  You can override them in
+``~/.spack/packages.yaml`` or ``etc/spack/packages.yaml``. For more
+details on how this works, see :ref:`configuration-scopes`.

+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+
+This example lists three installations of OpenMPI, one built with GCC,
+one built with GCC and debug information, and another built with Intel.
+If Spack is asked to build a package that uses one of these MPIs as a
+dependency, it will use the pre-installed OpenMPI in
+the given directory. Note that the specified path is the top-level
+install prefix, not the ``bin`` subdirectory.
+
+``packages.yaml`` can also be used to specify modules to load instead
+of the installation prefixes.  The following example says that module
+``CMake/3.7.2`` provides cmake version 3.7.2.
+
+.. code-block:: yaml
+
+   cmake:
+     externals:
+     - spec: cmake@3.7.2
+       modules:
+       - CMake/3.7.2
+
+Each ``packages.yaml`` begins with a ``packages:`` attribute, followed
+by a list of package names.  To specify externals, add an ``externals:``
+attribute under the package name, which lists externals.
+Each external should specify a ``spec:`` string that should be as
+well-defined as reasonably possible.  If a
+package lacks a spec component, such as missing a compiler or
+package version, then Spack will guess the missing component based
+on its most-favored packages, and it may guess incorrectly.
+
+Each package version and compiler listed in an external should
+have entries in Spack's packages and compiler configuration, even
+though the package and compiler may not ever be built.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Prevent packages from being built from sources
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Adding an external spec in ``packages.yaml`` allows Spack to use an external location,
+but it does not prevent Spack from building packages from sources. In the above example,
+Spack might choose for many valid reasons to start building and linking with the
+latest version of OpenMPI rather than continue using the pre-installed OpenMPI versions.
+
+To prevent this, the ``packages.yaml`` configuration also allows packages
+to be flagged as non-buildable.  The previous example could be modified to
+be:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+       buildable: False
+
+The addition of the ``buildable`` flag tells Spack that it should never build
+its own version of OpenMPI from sources, and it will instead always rely on a pre-built
+OpenMPI.
+
+.. note::
+
+   If ``concretizer:reuse`` is on (see :ref:`concretizer-options` for more information on that flag)
+   pre-built specs include specs already available from a local store, an upstream store, a registered
+   buildcache or specs marked as externals in ``packages.yaml``. If ``concretizer:reuse`` is off, only
+   external specs in ``packages.yaml`` are included in the list of pre-built specs.
+
+If an external module is specified as not buildable, then Spack will load the
+external module into the build environment which can be used for linking.
+
+The ``buildable`` does not need to be paired with external packages.
+It could also be used alone to forbid packages that may be
+buggy or otherwise undesirable.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Non-buildable virtual packages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Virtual packages in Spack can also be specified as not buildable, and
+external implementations can be provided. In the example above,
+OpenMPI is configured as not buildable, but Spack will often prefer
+other MPI implementations over the externally available OpenMPI. Spack
+can be configured with every MPI provider not buildable individually,
+but more conveniently:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       buildable: False
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+
+Spack can then use any of the listed external implementations of MPI
+to satisfy a dependency, and will choose depending on the compiler and
+architecture.
+
+In cases where the concretizer is configured to reuse specs, and other ``mpi`` providers
+(available via stores or buildcaches) are not wanted, Spack can be configured to require
+specs matching only the available externals:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       buildable: False
+       require:
+       - one_of: [
+           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64",
+           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug",
+           "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         ]
+     openmpi:
+       externals:
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.4.3
+       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
+         prefix: /opt/openmpi-1.4.3-debug
+       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
+         prefix: /opt/openmpi-1.6.5-intel
+
+This configuration prevents any spec using MPI and originating from stores or buildcaches to be reused,
+unless it matches the requirements under ``packages:mpi:require``. For more information on requirements see
+:ref:`package-requirements`.
+
+.. _cmd-spack-external-find:
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Automatically Find External Packages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can run the :ref:`spack external find <spack-external-find>` command
+to search for system-provided packages and add them to ``packages.yaml``.
+After running this command your ``packages.yaml`` may include new entries:
+
+.. code-block:: yaml
+
+   packages:
+     cmake:
+       externals:
+       - spec: cmake@3.17.2
+         prefix: /usr
+
+Generally this is useful for detecting a small set of commonly-used packages;
+for now this is generally limited to finding build-only dependencies.
+Specific limitations include:
+
+* Packages are not discoverable by default: For a package to be
+  discoverable with ``spack external find``, it needs to add special
+  logic. See :ref:`here <make-package-findable>` for more details.
+* The logic does not search through module files, it can only detect
+  packages with executables defined in ``PATH``; you can help Spack locate
+  externals which use module files by loading any associated modules for
+  packages that you want Spack to know about before running
+  ``spack external find``.
+* Spack does not overwrite existing entries in the package configuration:
+  If there is an external defined for a spec at any configuration scope,
+  then Spack will not add a new external entry (``spack config blame packages``
+  can help locate all external entries).

+----------------------
+Concretizer options
+----------------------
 
-The ``concretizer.yaml`` configuration file allows to customize aspects of the
-algorithm used to select the dependencies you install. The default configuration
-is the following:
+``packages.yaml`` gives the concretizer preferences for specific packages,
+but you can also use ``concretizer.yaml`` to customize aspects of the
+algorithm it uses to select the dependencies you install:

    :language: yaml
 
---------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 Reuse already installed packages
---------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-The ``reuse`` attribute controls how aggressively Spack reuses binary packages during concretization. The
-attribute can either be a single value, or an object for more complex configurations.
-
-In the former case ("single value") it allows Spack to:
-
-1. Reuse installed packages and buildcaches for all the specs to be concretized, when ``true``
-2. Reuse installed packages and buildcaches only for the dependencies of the root specs, when ``dependencies``
-3. Disregard reusing installed packages and buildcaches, when ``false``
-
-In case a finer control over which specs are reused is needed, then the value of this attribute can be
-an object, with the following keys:
-
-1. ``roots``: if ``true`` root specs are reused, if ``false`` only dependencies of root specs are reused
-2. ``from``: list of sources from which reused specs are taken
-
-Each source in ``from`` is itself an object:
-
-.. list-table:: Attributes for a source or reusable specs
-   :header-rows: 1
-
-   * - Attribute name
-     - Description
-   * - type (mandatory, string)
-     - Can be ``local``, ``buildcache``, or ``external``
-   * - include (optional, list of specs)
-     - If present, reusable specs must match at least one of the constraint in the list
-   * - exclude (optional, list of specs)
-     - If present, reusable specs must not match any of the constraint in the list.
-
-For instance, the following configuration:
-
-.. code-block:: yaml
-
-   concretizer:
-     reuse:
-       roots: true
-       from:
-       - type: local
-         include:
-         - "%gcc"
-         - "%clang"
-
-tells the concretizer to reuse all specs compiled with either ``gcc`` or ``clang``, that are installed
-in the local store. Any spec from remote buildcaches is disregarded.
-
-To reduce the boilerplate in configuration files, default values for the ``include`` and
-``exclude`` options can be pushed up one level:
-
-.. code-block:: yaml
-
-   concretizer:
-     reuse:
-       roots: true
-       include:
-       - "%gcc"
-       from:
-       - type: local
-       - type: buildcache
-       - type: local
-         include:
-         - "foo %oneapi"
-
-In the example above we reuse all specs compiled with ``gcc`` from the local store
-and remote buildcaches, and we also reuse ``foo %oneapi``. Note that the last source of
-specs override the default ``include`` attribute.
-
-For one-off concretizations, the are command line arguments for each of the simple "single value"
-configurations. This means a user can:
+The ``reuse`` attribute controls whether Spack will prefer to use installed packages (``true``), or

 .. code-block:: console

-Duplicate nodes
----------------
+.. _package-requirements:
 
-The ``duplicates`` attribute controls whether the DAG can contain multiple configurations of
-the same package. This is mainly relevant for build dependencies, which may have their version
-pinned by some nodes, and thus be required at different versions by different nodes in the same
-DAG.
+--------------------
+Package Requirements
+--------------------
 
-The ``strategy`` option controls how the solver deals with duplicates. If the value is ``none``,
-then a single configuration per package is allowed in the DAG. This means, for instance, that only
-a single ``cmake`` or a single ``py-setuptools`` version is allowed. The result would be a slightly
-faster concretization, at the expense of making a few specs unsolvable.
+Spack can be configured to always use certain compilers, package
+versions, and variants during concretization through package
+requirements.
 
-If the value is ``minimal`` Spack will allow packages tagged as ``build-tools`` to have duplicates.
-This allows, for instance, to concretize specs whose nodes require different, and incompatible, ranges
-of some build tool. For instance, in the figure below the latest `py-shapely` requires a newer `py-setuptools`,
-while `py-numpy` still needs an older version:
+Package requirements are useful when you find yourself repeatedly
+specifying the same constraints on the command line, and wish that
+Spack respects these constraints whether you mention them explicitly
+or not. Another use case is specifying constraints that should apply
+to all root specs in an environment, without having to repeat the
+constraint everywhere.
 
-.. figure::  images/shapely_duplicates.svg
-   :scale: 70 %
-   :align: center
+Apart from that, requirements config is more flexible than constraints
+on the command line, because it can specify constraints on packages
+*when they occur* as a dependency. In contrast, on the command line it
+is not possible to specify constraints on dependencies while also keeping
+those dependencies optional.
 
-Up to Spack v0.20 ``duplicates:strategy:none`` was the default (and only) behavior. From Spack v0.21 the
-default behavior is ``duplicates:strategy:minimal``.
+^^^^^^^^^^^^^^^^^^^
+Requirements syntax
+^^^^^^^^^^^^^^^^^^^
+
+The package requirements configuration is specified in ``packages.yaml``,
+keyed by package name and expressed using the Spec syntax. In the simplest
+case you can specify attributes that you always want the package to have
+by providing a single spec string to ``require``:
+
+.. code-block:: yaml
+
+   packages:
+     libfabric:
+       require: "@1.13.2"
+
+In the above example, ``libfabric`` will always build with version 1.13.2. If you
+need to compose multiple configuration scopes ``require`` accepts a list of
+strings:
+
+.. code-block:: yaml
+
+   packages:
+     libfabric:
+       require:
+       - "@1.13.2"
+       - "%gcc"
+
+In this case ``libfabric`` will always build with version 1.13.2 **and** using GCC
+as a compiler.
+
+For more complex use cases, require accepts also a list of objects. These objects
+must have either a ``any_of`` or a ``one_of`` field, containing a list of spec strings,
+and they can optionally have a ``when`` and a ``message`` attribute:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       require:
+       - any_of: ["@4.1.5", "%gcc"]
+         message: "in this example only 4.1.5 can build with other compilers"
+
+``any_of`` is a list of specs. One of those specs must be satisfied
+and it is also allowed for the concretized spec to match more than one.
+In the above example, that means you could build ``openmpi@4.1.5%gcc``,
+``openmpi@4.1.5%clang`` or ``openmpi@3.9%gcc``, but
+not ``openmpi@3.9%clang``.
+
+If a custom message is provided, and the requirement is not satisfiable,
+Spack will print the custom error message:
+
+.. code-block:: console
+
+   $ spack spec openmpi@3.9%clang
+   ==> Error: in this example only 4.1.5 can build with other compilers
+
+We could express a similar requirement using the ``when`` attribute:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       require:
+       - any_of: ["%gcc"]
+         when: "@:4.1.4"
+         message: "in this example only 4.1.5 can build with other compilers"
+
+In the example above, if the version turns out to be 4.1.4 or less, we require the compiler to be GCC.
+For readability, Spack also allows a ``spec`` key accepting a string when there is only a single
+constraint:
+
+.. code-block:: yaml
+
+   packages:
+     openmpi:
+       require:
+       - spec: "%gcc"
+         when: "@:4.1.4"
+         message: "in this example only 4.1.5 can build with other compilers"
+
+This code snippet and the one before it are semantically equivalent.
+
+Finally, instead of ``any_of`` you can use ``one_of`` which also takes a list of specs. The final
+concretized spec must match one and only one of them:
+
+.. code-block:: yaml
+
+   packages:
+     mpich:
+       require:
+       - one_of: ["+cuda", "+rocm"]
+
+In the example above, that means you could build ``mpich+cuda`` or ``mpich+rocm`` but not ``mpich+cuda+rocm``.
+
+.. note::
+
+   For ``any_of`` and ``one_of``, the order of specs indicates a
+   preference: items that appear earlier in the list are preferred
+   (note that these preferences can be ignored in favor of others).
+
+.. note::
+
+   When using a conditional requirement, Spack is allowed to actively avoid the triggering
+   condition (the ``when=...`` spec) if that leads to a concrete spec with better scores in
+   the optimization criteria. To check the current optimization criteria and their
+   priorities you can run ``spack solve zlib``.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Setting default requirements
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can also set default requirements for all packages under ``all``
+like this:
+
+.. code-block:: yaml
+
+   packages:
+     all:
+       require: '%clang'
+
+which means every spec will be required to use ``clang`` as a compiler.
+
+Note that in this case ``all`` represents a *default set of requirements* -
+if there are specific package requirements, then the default requirements
+under ``all`` are disregarded. For example, with a configuration like this:
+
+.. code-block:: yaml
+
+   packages:
+     all:
+       require: '%clang'
+     cmake:
+       require: '%gcc'
+
+Spack requires ``cmake`` to use ``gcc`` and all other nodes (including ``cmake``
+dependencies) to use ``clang``.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Setting requirements on virtual specs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A requirement on a virtual spec applies whenever that virtual is present in the DAG.
+This can be useful for fixing which virtual provider you want to use:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       require: 'mvapich2 %gcc'
+
+With the configuration above the only allowed ``mpi`` provider is ``mvapich2 %gcc``.
+
+Requirements on the virtual spec and on the specific provider are both applied, if
+present. For instance with a configuration like:
+
+.. code-block:: yaml
+
+   packages:
+     mpi:
+       require: 'mvapich2 %gcc'
+     mvapich2:
+       require: '~cuda'
+
+you will use ``mvapich2~cuda %gcc`` as an ``mpi`` provider.
+
+.. _package-preferences:
+
+-------------------
+Package Preferences
+-------------------
+
+In some cases package requirements can be too strong, and package
+preferences are the better option. Package preferences do not impose
+constraints on packages for particular versions or variants values,
+they rather only set defaults -- the concretizer is free to change
+them if it must due to other constraints. Also note that package
+preferences are of lower priority than reuse of already installed
+packages.
+
+Here's an example ``packages.yaml`` file that sets preferred packages:
+
+.. code-block:: yaml
+
+   packages:
+     opencv:
+       compiler: [gcc@4.9]
+       variants: +debug
+     gperftools:
+       version: [2.2, 2.4, 2.3]
+     all:
+       compiler: [gcc@4.4.7, 'gcc@4.6:', intel, clang, pgi]
+       target: [sandybridge]
+       providers:
+         mpi: [mvapich2, mpich, openmpi]
+
+At a high level, this example is specifying how packages are preferably
+concretized.  The opencv package should prefer using GCC 4.9 and
+be built with debug options.  The gperftools package should prefer version
+2.2 over 2.4.  Every package on the system should prefer mvapich2 for
+its MPI and GCC 4.4.7 (except for opencv, which overrides this by preferring GCC 4.9).
+These options are used to fill in implicit defaults.  Any of them can be overwritten
+on the command line if explicitly requested.
+
+Package preferences accept the follow keys or components under
+the specific package (or ``all``) section: ``compiler``, ``variants``,
+``version``, ``providers``, and ``target``.  Each component has an
+ordered list of spec ``constraints``, with earlier entries in the
+list being preferred over later entries.
+
+Sometimes a package installation may have constraints that forbid
+the first concretization rule, in which case Spack will use the first
+legal concretization rule.  Going back to the example, if a user
+requests gperftools 2.3 or later, then Spack will install version 2.4
+as the 2.4 version of gperftools is preferred over 2.3.
+
+An explicit concretization rule in the preferred section will always
+take preference over unlisted concretizations.  In the above example,
+xlc isn't listed in the compiler list.  Every listed compiler from
+gcc to pgi will thus be preferred over the xlc compiler.
+
+The syntax for the ``provider`` section differs slightly from other
+concretization rules.  A provider lists a value that packages may
+``depends_on`` (e.g, MPI) and a list of rules for fulfilling that
+dependency.
+
+.. _package_permissions:
+
+-------------------
+Package Permissions
+-------------------
+
+Spack can be configured to assign permissions to the files installed
+by a package.
+
+In the ``packages.yaml`` file under ``permissions``, the attributes
+``read``, ``write``, and ``group`` control the package
+permissions. These attributes can be set per-package, or for all
+packages under ``all``. If permissions are set under ``all`` and for a
+specific package, the package-specific settings take precedence.
+
+The ``read`` and ``write`` attributes take one of ``user``, ``group``,
+and ``world``.
+
+.. code-block:: yaml
+
+  packages:
+    all:
+      permissions:
+        write: group
+        group: spack
+    my_app:
+      permissions:
+        read: group
+        group: my_team
+
+The permissions settings describe the broadest level of access to
+installations of the specified packages. The execute permissions of
+the file are set to the same level as read permissions for those files
+that are executable. The default setting for ``read`` is ``world``,
+and for ``write`` is ``user``. In the example above, installations of
+``my_app`` will be installed with user and group permissions but no
+world permissions, and owned by the group ``my_team``. All other
+packages will be installed with user and group write privileges, and
+world read privileges. Those packages will be owned by the group
+``spack``.
+
+The ``group`` attribute assigns a Unix-style group to a package. All
+files installed by the package will be owned by the assigned group,
+and the sticky group bit will be set on the install prefix and all
+directories inside the install prefix. This will ensure that even
+manually placed files within the install prefix are owned by the
+assigned group. If no group is assigned, Spack will allow the OS
+default behavior to go as expected.
+
+----------------------------
+Assigning Package Attributes
+----------------------------
+
+You can assign class-level attributes in the configuration:
+
+.. code-block:: yaml
+
+  packages:
+    mpileaks:
+      # Override existing attributes
+      url: http://www.somewhereelse.com/mpileaks-1.0.tar.gz
+      # ... or add new ones
+      x: 1
+
+Attributes set this way will be accessible to any method executed
+in the package.py file (e.g. the ``install()`` method). Values for these

-^^^^^^^
-
-``PerlPackage`` provides a simple stand-alone test of the successfully
-installed package to confirm that installed perl module(s) can be used.
-These tests can be performed any time after the installation using
-``spack -v test run``. (For more information on the command, see 
-:ref:`cmd-spack-test-run`.)
-
-The base class automatically detects perl modules based on the presence
-of ``*.pm`` files under the package's library directory. For example,
-the files under ``perl-bignum``'s perl library are:
-
-.. code-block:: console
-
-   $ find . -name "*.pm"
-   ./bigfloat.pm
-   ./bigrat.pm
-   ./Math/BigFloat/Trace.pm
-   ./Math/BigInt/Trace.pm
-   ./Math/BigRat/Trace.pm
-   ./bigint.pm
-   ./bignum.pm
-
-
-which results in the package having the ``use_modules`` property containing:
-
-.. code-block:: python
-
-   use_modules = [
-       "bigfloat",
-       "bigrat",
-       "Math::BigFloat::Trace",
-       "Math::BigInt::Trace",
-       "Math::BigRat::Trace",
-       "bigint",
-       "bignum",
-   ]
-
-.. note::
-
-   This list can often be used to catch missing dependencies.
-
-If the list is somehow wrong, you can provide the names of the modules
-yourself by overriding ``use_modules`` like so:
-
- .. code-block:: python
-
-    use_modules = ["bigfloat", "bigrat", "bigint", "bignum"]
-
-If you only want a subset of the automatically detected modules to be
-tested, you could instead define the ``skip_modules`` property on the
-package. So, instead of overriding ``use_modules`` as shown above, you
-could define the following:
-
- .. code-block:: python
-
-    skip_modules = [
-        "Math::BigFloat::Trace",
-        "Math::BigInt::Trace",

+extends vs. depends_on

+This is very similar to the naming dilemma above, with a slight twist.
 As mentioned in the :ref:`Packaging Guide <packaging_extensions>`,
 ``extends`` and ``depends_on`` are very similar, but ``extends`` ensures
 that the extension and extendee share the same prefix in views.
 This allows the user to import a Python module without
 having to add that module to ``PYTHONPATH``.
 
-Additionally, ``extends("python")`` adds a dependency on the package
-``python-venv``. This improves isolation from the system, whether
-it's during the build or at runtime: user and system site packages
-cannot accidentally be used by any package that ``extends("python")``.
-
-As a rule of thumb: if a package does not install any Python modules
-of its own, and merely puts a Python script in the ``bin`` directory,
-then there is no need for ``extends``. If the package installs modules
-in the ``site-packages`` directory, it requires ``extends``.

-"""""""""""""""""""""""""""""""""""""
-Executing ``python`` during the build
-"""""""""""""""""""""""""""""""""""""
-
-Whenever you need to execute a Python command or pass the path of the
-Python interpreter to the build system, it is best to use the global
-variable ``python`` directly. For example:
-
-.. code-block:: python
-
-    @run_before("install")
-    def recythonize(self):
-        python("setup.py", "clean")  # use the `python` global
-
-As mentioned in the previous section, ``extends("python")`` adds an
-automatic dependency on ``python-venv``, which is a virtual environment
-that guarantees build isolation. The ``python`` global always refers to
-the correct Python interpreter, whether the package uses ``extends("python")``
-or ``depends_on("python")``.
+When deciding between ``extends`` and ``depends_on``, the best rule of
+thumb is to check the installation prefix. If Python libraries are
+installed to ``<prefix>/lib/pythonX.Y/site-packages``, then you
+should use ``extends``. If Python libraries are installed elsewhere
+or the only files that get installed reside in ``<prefix>/bin``, then
+don't use ``extends``.

 Container Images
 ================
 
-Spack :ref:`environments` can easily be turned into container images. This page
-outlines two ways in which this can be done:
-
-1. By installing the environment on the host system, and copying the installations
-   into the container image. This approach does not require any tools like Docker
-   or Singularity to be installed.
-2. By generating a Docker or Singularity recipe that can be used to build the
-   container image. In this approach, Spack builds the software inside the
-   container runtime, not on the host system.
-
-The first approach is easiest if you already have an installed environment,
-the second approach gives more control over the container image.
-
----------------------------
-From existing installations
----------------------------
-
-If you already have a Spack environment installed on your system, you can
-share the binaries as an OCI compatible container image. To get started you
-just have to configure and OCI registry and run ``spack buildcache push``.
-
-.. code-block:: console
-  
-   # Create and install an environment in the current directory
-   spack env create -d .
-   spack -e . add pkg-a pkg-b
-   spack -e . install
-
-   # Configure the registry
-   spack -e . mirror add --oci-username ... --oci-password ... container-registry oci://example.com/name/image
-
-   # Push the image
-   spack -e . buildcache push --update-index --base-image ubuntu:22.04 --tag my_env container-registry
-
-The resulting container image can then be run as follows:
-
-.. code-block:: console
-
-   $ docker run -it example.com/name/image:my_env
-
-The image generated by Spack consists of the specified base image with each package from the
-environment as a separate layer on top. The image is minimal by construction, it only contains the
-environment roots and its runtime dependencies.
-
-.. note::
-
-  When using registries like GHCR and Docker Hub, the ``--oci-password`` flag is not
-  the password for your account, but a personal access token you need to generate separately.
-
-The specified ``--base-image`` should have a libc that is compatible with the host system.
-For example if your host system is Ubuntu 20.04, you can use ``ubuntu:20.04``, ``ubuntu:22.04``
-or newer: the libc in the container image must be at least the version of the host system,
-assuming ABI compatibility. It is also perfectly fine to use a completely different
-Linux distribution as long as the libc is compatible.
-
-For convenience, Spack also turns the OCI registry into a :ref:`build cache <binary_caches_oci>`,
-so that future ``spack install`` of the environment will simply pull the binaries from the
-registry instead of doing source builds. The flag ``--update-index`` is needed to make Spack
-take the build cache into account when concretizing.
-
-.. note::
-
-  When generating container images in CI, the approach above is recommended when CI jobs
-  already run in a sandboxed environment. You can simply use ``spack`` directly
-  in the CI job and push the resulting image to a registry. Subsequent CI jobs should
-  run faster because Spack can install from the same registry instead of rebuilding from
-  sources.
-
----------------------------------------------
-Generating recipes for Docker and Singularity
----------------------------------------------
-
-Apart from copying existing installations into container images, Spack can also
-generate recipes for container images. This is useful if you want to run Spack
-itself in a sandboxed environment instead of on the host system.
-
-Since recipes need a little bit more boilerplate than
+Spack :ref:`environments` are a great tool to create container images, but
+preparing one that is suitable for production requires some more boilerplate
+than just:
 
 .. code-block:: docker
 
    COPY spack.yaml /environment
    RUN spack -e /environment install
 
-Spack provides a command to generate customizable recipes for container images. Customizations
-include minimizing the size of the image, installing packages in the base image using the system
-package manager, and setting up a proper entrypoint to run the image.
+Additional actions may be needed to minimize the size of the
+container, or to update the system software that is installed in the base
+image, or to set up a proper entrypoint to run the image. These tasks are
+usually both necessary and repetitive, so Spack comes with a command
+to generate recipes for container images starting from a ``spack.yaml``.

-Included Concrete Environments
-------------------------------
-
-Spack environments can create an environment based off of information in already
-established environments. You can think of it as a combination of existing
-environments. It will gather information from the existing environment's
-``spack.lock`` and use that during the creation of this included concrete
-environment. When an included concrete environment is created it will generate
-a ``spack.lock`` file for the newly created environment.
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Creating included environments
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-To create a combined concrete environment, you must have at least one existing
-concrete environment. You will use the command ``spack env create`` with the
-argument ``--include-concrete`` followed by the name or path of the environment
-you'd like to include. Here is an example of how to create a combined environment
-from the command line.
-
-.. code-block:: console
-
-   $ spack env create myenv
-   $ spack -e myenv add python
-   $ spack -e myenv concretize
-   $ spack env create --include-concrete myenv included_env
-
-
-You can also include an environment directly in the ``spack.yaml`` file. It
-involves adding the ``include_concrete`` heading in the yaml followed by the
-absolute path to the independent environments.
-
-.. code-block:: yaml
-
-   spack:
-     specs: []
-     concretizer:
-         unify: true
-     include_concrete:
-     - /absolute/path/to/environment1
-     - /absolute/path/to/environment2
-
-
-Once the ``spack.yaml`` has been updated you must concretize the environment to
-get the concrete specs from the included environments.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Updating an included environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-If changes were made to the base environment and you want that reflected in the
-included environment you will need to reconcretize both the base environment and the
-included environment for the change to be implemented. For example:
-
-.. code-block:: console
-
-   $ spack env create myenv
-   $ spack -e myenv add python
-   $ spack -e myenv concretize
-   $ spack env create --include-concrete myenv included_env

-   $ spack -e included_env find
-   ==> In environment included_env
-   ==> No root specs
-   ==> Included specs
-   python
-
-   ==> 0 installed packages
-
-Here we see that ``included_env`` has access to the python package through
-the ``myenv`` environment. But if we were to add another spec to ``myenv``,
-``included_env`` will not be able to access the new information.
-
-.. code-block:: console

-
------------------------------------------------------
-Why does Spack pick particular versions and variants?
------------------------------------------------------
-
-This question comes up in a variety of forms:
-
- 1. Why does Spack seem to ignore my package preferences from ``packages.yaml`` config?
- 2. Why does Spack toggle a variant instead of using the default from the ``package.py`` file?
-
-The short answer is that Spack always picks an optimal configuration
-based on a complex set of criteria\ [#f1]_. These criteria are more nuanced
-than always choosing the latest versions or default variants.
-
-.. note::
-
-    As a rule of thumb: requirements + constraints > reuse > preferences > defaults.
-
-The following set of criteria (from lowest to highest precedence) explain
-common cases where concretization output may seem surprising at first.
-
-1. :ref:`Package preferences <package-preferences>` configured in ``packages.yaml``
-   override variant defaults from ``package.py`` files, and influence the optimal
-   ordering of versions. Preferences are specified as follows:
-
-   .. code-block:: yaml
-
-      packages:
-        foo:
-          version: [1.0, 1.1]
-          variants: ~mpi
-
-2. :ref:`Reuse concretization <concretizer-options>` configured in ``concretizer.yaml``
-   overrides preferences, since it's typically faster to reuse an existing spec than to
-   build a preferred one from sources. When build caches are enabled, specs may be reused
-   from a remote location too. Reuse concretization is configured as follows:
-
-   .. code-block:: yaml
-
-      concretizer:
-        reuse: dependencies  # other options are 'true' and 'false'
-
-3. :ref:`Package requirements <package-requirements>` configured in ``packages.yaml``,
-   and constraints from the command line as well as ``package.py`` files override all
-   of the above. Requirements are specified as follows:
-
-   .. code-block:: yaml
-
-      packages:
-        foo:
-          require:
-          - "@1.2: +mpi"
-
-Requirements and constraints restrict the set of possible solutions, while reuse
-behavior and preferences influence what an optimal solution looks like.

+.. _cray-support:
+
+-------------
+Spack on Cray
+-------------
+
+Spack differs slightly when used on a Cray system. The architecture spec
+can differentiate between the front-end and back-end processor and operating system.
+For example, on Edison at NERSC, the back-end target processor
+is "Ivy Bridge", so you can specify to use the back-end this way:
+
+.. code-block:: console
+
+   $ spack install zlib target=ivybridge
+
+You can also use the operating system to build against the back-end:
+
+.. code-block:: console
+
+   $ spack install zlib os=CNL10
+
+Notice that the name includes both the operating system name and the major
+version number concatenated together.
+
+Alternatively, if you want to build something for the front-end,
+you can specify the front-end target processor. The processor for a login node
+on Edison is "Sandy bridge" so we specify on the command line like so:
+
+.. code-block:: console
+
+   $ spack install zlib target=sandybridge
+
+And the front-end operating system is:
+
+.. code-block:: console
+
+   $ spack install zlib os=SuSE11
+
+^^^^^^^^^^^^^^^^^^^^^^^
+Cray compiler detection
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Spack can detect compilers using two methods. For the front-end, we treat
+everything the same. The difference lies in back-end compiler detection.
+Back-end compiler detection is made via the Tcl module avail command.
+Once it detects the compiler it writes the appropriate PrgEnv and compiler
+module name to compilers.yaml and sets the paths to each compiler with Cray\'s
+compiler wrapper names (i.e. cc, CC, ftn). During build time, Spack will load
+the correct PrgEnv and compiler module and will call appropriate wrapper.
+
+The compilers.yaml config file will also differ. There is a
+modules section that is filled with the compiler's Programming Environment
+and module name. On other systems, this field is empty []:
+
+.. code-block:: yaml
+
+   - compiler:
+       modules:
+         - PrgEnv-intel
+         - intel/15.0.109
+
+As mentioned earlier, the compiler paths will look different on a Cray system.
+Since most compilers are invoked using cc, CC and ftn, the paths for each
+compiler are replaced with their respective Cray compiler wrapper names:
+
+.. code-block:: yaml
+
+     paths:
+       cc: cc
+       cxx: CC
+       f77: ftn
+       fc: ftn
+
+As opposed to an explicit path to the compiler executable. This allows Spack
+to call the Cray compiler wrappers during build time.
+
+For more on compiler configuration, check out :ref:`compiler-config`.
+
+Spack sets the default Cray link type to dynamic, to better match other
+other platforms. Individual packages can enable static linking (which is the
+default outside of Spack on cray systems) using the ``-static`` flag.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Setting defaults and using Cray modules
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you want to use default compilers for each PrgEnv and also be able
+to load cray external modules, you will need to set up a ``packages.yaml``.
+
+Here's an example of an external configuration for cray modules:
+
+.. code-block:: yaml
+
+   packages:
+     mpich:
+       externals:
+       - spec: "mpich@7.3.1%gcc@5.2.0 arch=cray_xc-haswell-CNL10"
+         modules:
+         - cray-mpich
+       - spec: "mpich@7.3.1%intel@16.0.0.109 arch=cray_xc-haswell-CNL10"
+         modules:
+         - cray-mpich
+     all:
+       providers:
+         mpi: [mpich]
+
+This tells Spack that for whatever package that depends on mpi, load the
+cray-mpich module into the environment. You can then be able to use whatever
+environment variables, libraries, etc, that are brought into the environment
+via module load.
+
+.. note::
+
+    For Cray-provided packages, it is best to use ``modules:`` instead of ``prefix:``
+    in ``packages.yaml``, because the Cray Programming Environment heavily relies on
+    modules (e.g., loading the ``cray-mpich`` module adds MPI libraries to the
+    compiler wrapper link line).
+
+You can set the default compiler that Spack can use for each compiler type.
+If you want to use the Cray defaults, then set them under ``all:`` in packages.yaml.
+In the compiler field, set the compiler specs in your order of preference.
+Whenever you build with that compiler type, Spack will concretize to that version.
+
+Here is an example of a full packages.yaml used at NERSC
+
+.. code-block:: yaml
+
+   packages:
+     mpich:
+       externals:
+       - spec: "mpich@7.3.1%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge"
+         modules:
+         - cray-mpich
+       - spec: "mpich@7.3.1%intel@16.0.0.109 arch=cray_xc-SuSE11-ivybridge"
+         modules:
+         - cray-mpich
+       buildable: False
+     netcdf:
+       externals:
+       - spec: "netcdf@4.3.3.1%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge"
+         modules:
+         - cray-netcdf
+       - spec: "netcdf@4.3.3.1%intel@16.0.0.109 arch=cray_xc-CNL10-ivybridge"
+         modules:
+         - cray-netcdf
+       buildable: False
+     hdf5:
+       externals:
+       - spec: "hdf5@1.8.14%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge"
+         modules:
+         - cray-hdf5
+       - spec: "hdf5@1.8.14%intel@16.0.0.109 arch=cray_xc-CNL10-ivybridge"
+         modules:
+         - cray-hdf5
+       buildable: False
+     all:
+       compiler: [gcc@5.2.0, intel@16.0.0.109]
+       providers:
+         mpi: [mpich]
+
+Here we tell spack that whenever we want to build with gcc use version 5.2.0 or
+if we want to build with intel compilers, use version 16.0.0.109. We add a spec
+for each compiler type for each cray modules. This ensures that for each
+compiler on our system we can use that external module.
+
+For more on external packages check out the section :ref:`sec-external-packages`.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Using Linux containers on Cray machines
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Spack uses environment variables particular to the Cray programming
+environment to determine which systems are Cray platforms. These
+environment variables may be propagated into containers that are not
+using the Cray programming environment.
+
+To ensure that Spack does not autodetect the Cray programming
+environment, unset the environment variable ``MODULEPATH``. This
+will cause Spack to treat a linux container on a Cray system as a base
+linux distro.

-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Autoloading and hiding dependencies
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-A module file should set the variables that are needed for an application to work. But since an
-application often has many dependencies, where should all the environment variables for those be
-set? In Spack the rule is that each package sets the runtime variables that are needed by the
-package itself, and no more. This way, dependencies can be loaded standalone too, and duplication
-of environment variables is avoided.
-
-That means however that if you want to use an application, you need to load the modules for all its
-dependencies. Of course this is not something you would want users to do manually.
-
-Since Spack knows the dependency graph of every package, it can easily generate module files that
-automatically load the modules for its dependencies recursively. It is enabled by default for both
-Lmod and Environment Modules under the ``autoload: direct`` config option. The former system has
-builtin support through the ``depends_on`` function, the latter simply uses a ``module load``
-statement. Both module systems (at least in newer versions) do reference counting, so that if a
-module is loaded by two different modules, it will only be unloaded after the others are.
-
-The ``autoload`` key accepts the values:
-
-  * ``none``: no autoloading
-  * ``run``: autoload direct *run* type dependencies
-  * ``direct``: autoload direct *link and run* type dependencies
-  * ``all``: autoload all dependencies
-
-In case of ``run`` and ``direct``, a ``module load`` triggers a recursive load.
-
-The ``direct`` option is most correct: there are cases where pure link dependencies need to set
-variables for themselves, or need to have variables of their own dependencies set.
-
-In practice however, ``run`` is often sufficient, and may make ``module load`` snappier.
-
-The ``all`` option is discouraged and seldomly used.
-
-A common complaint about autoloading is the large number of modules that are visible to the user.
-Spack has a solution for this as well: ``hide_implicits: true``. This ensures that only those
-packages you've explicitly installed are exposed by ``module avail``, but still allows for
-autoloading of hidden dependencies. Lmod should support hiding implicits in general, while
-Environment Modules requires version 4.7 or higher.
-
-.. note::
-   If supported by your module system, we highly encourage the following configuration that enables
-   autoloading and hiding of implicits. It ensures all runtime variables are set correctly,
-   including those for dependencies, without overwhelming the user with a large number of available
-   modules. Further, it makes it easier to get readable module names without collisions, see the

-================================
-Package Settings (packages.yaml)
-================================
-
-Spack allows you to customize how your software is built through the
-``packages.yaml`` file.  Using it, you can make Spack prefer particular
-implementations of virtual dependencies (e.g., MPI or BLAS/LAPACK),
-or you can make it prefer to build with particular compilers.  You can
-also tell Spack to use *external* software installations already
-present on your system.
-
-At a high level, the ``packages.yaml`` file is structured like this:
-
-.. code-block:: yaml
-
-   packages:
-     package1:
-       # settings for package1
-     package2:
-       # settings for package2
-     # ...
-     all:
-       # settings that apply to all packages.
-
-So you can either set build preferences specifically for *one* package,
-or you can specify that certain settings should apply to *all* packages.
-The types of settings you can customize are described in detail below.
-
-Spack's build defaults are in the default
-``etc/spack/defaults/packages.yaml`` file.  You can override them in
-``~/.spack/packages.yaml`` or ``etc/spack/packages.yaml``. For more
-details on how this works, see :ref:`configuration-scopes`.
-
-.. _sec-external-packages:
-
------------------
-External Packages
------------------
-
-Spack can be configured to use externally-installed
-packages rather than building its own packages. This may be desirable
-if machines ship with system packages, such as a customized MPI
-that should be used instead of Spack building its own MPI.
-
-External packages are configured through the ``packages.yaml`` file.
-Here's an example of an external configuration:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-
-This example lists three installations of OpenMPI, one built with GCC,
-one built with GCC and debug information, and another built with Intel.
-If Spack is asked to build a package that uses one of these MPIs as a
-dependency, it will use the pre-installed OpenMPI in
-the given directory. Note that the specified path is the top-level
-install prefix, not the ``bin`` subdirectory.
-
-``packages.yaml`` can also be used to specify modules to load instead
-of the installation prefixes.  The following example says that module
-``CMake/3.7.2`` provides cmake version 3.7.2.
-
-.. code-block:: yaml
-
-   cmake:
-     externals:
-     - spec: cmake@3.7.2
-       modules:
-       - CMake/3.7.2
-
-Each ``packages.yaml`` begins with a ``packages:`` attribute, followed
-by a list of package names.  To specify externals, add an ``externals:``
-attribute under the package name, which lists externals.
-Each external should specify a ``spec:`` string that should be as
-well-defined as reasonably possible.  If a
-package lacks a spec component, such as missing a compiler or
-package version, then Spack will guess the missing component based
-on its most-favored packages, and it may guess incorrectly.
-
-Each package version and compiler listed in an external should
-have entries in Spack's packages and compiler configuration, even
-though the package and compiler may not ever be built.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Extra attributes for external packages
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Sometimes external packages require additional attributes to be used
-effectively. This information can be defined on a per-package basis
-and stored in the ``extra_attributes`` section of the external package
-configuration. In addition to per-package information, this section
-can be used to define environment modifications to be performed
-whenever the package is used. For example, if an external package is
-built without ``rpath`` support, it may require ``LD_LIBRARY_PATH``
-settings to find its dependencies. This could be configured as
-follows:
-
-.. code-block:: yaml
-
-   packages:
-     mpich:
-       externals:
-       - spec: mpich@3.3 %clang@12.0.0 +hwloc
-         prefix: /path/to/mpich
-         extra_attributes:
-           environment:
-             prepend_path:
-               LD_LIBRARY_PATH: /path/to/hwloc/lib64
-
-See :ref:`configuration_environment_variables` for more information on
-how to configure environment modifications in Spack config files.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Prevent packages from being built from sources
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Adding an external spec in ``packages.yaml`` allows Spack to use an external location,
-but it does not prevent Spack from building packages from sources. In the above example,
-Spack might choose for many valid reasons to start building and linking with the
-latest version of OpenMPI rather than continue using the pre-installed OpenMPI versions.
-
-To prevent this, the ``packages.yaml`` configuration also allows packages
-to be flagged as non-buildable.  The previous example could be modified to
-be:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-       buildable: False
-
-The addition of the ``buildable`` flag tells Spack that it should never build
-its own version of OpenMPI from sources, and it will instead always rely on a pre-built
-OpenMPI.
-
-.. note::
-
-   If ``concretizer:reuse`` is on (see :ref:`concretizer-options` for more information on that flag)
-   pre-built specs include specs already available from a local store, an upstream store, a registered
-   buildcache or specs marked as externals in ``packages.yaml``. If ``concretizer:reuse`` is off, only
-   external specs in ``packages.yaml`` are included in the list of pre-built specs.
-
-If an external module is specified as not buildable, then Spack will load the
-external module into the build environment which can be used for linking.
-
-The ``buildable`` does not need to be paired with external packages.
-It could also be used alone to forbid packages that may be
-buggy or otherwise undesirable.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Non-buildable virtual packages
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Virtual packages in Spack can also be specified as not buildable, and
-external implementations can be provided. In the example above,
-OpenMPI is configured as not buildable, but Spack will often prefer
-other MPI implementations over the externally available OpenMPI. Spack
-can be configured with every MPI provider not buildable individually,
-but more conveniently:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       buildable: False
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-
-Spack can then use any of the listed external implementations of MPI
-to satisfy a dependency, and will choose depending on the compiler and
-architecture.
-
-In cases where the concretizer is configured to reuse specs, and other ``mpi`` providers
-(available via stores or buildcaches) are not wanted, Spack can be configured to require
-specs matching only the available externals:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       buildable: False
-       require:
-       - one_of: [
-           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64",
-           "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug",
-           "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         ]
-     openmpi:
-       externals:
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.4.3
-       - spec: "openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug"
-         prefix: /opt/openmpi-1.4.3-debug
-       - spec: "openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64"
-         prefix: /opt/openmpi-1.6.5-intel
-
-This configuration prevents any spec using MPI and originating from stores or buildcaches to be reused,
-unless it matches the requirements under ``packages:mpi:require``. For more information on requirements see
-:ref:`package-requirements`.
-
-.. _cmd-spack-external-find:
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Automatically Find External Packages
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can run the :ref:`spack external find <spack-external-find>` command
-to search for system-provided packages and add them to ``packages.yaml``.
-After running this command your ``packages.yaml`` may include new entries:
-
-.. code-block:: yaml
-
-   packages:
-     cmake:
-       externals:
-       - spec: cmake@3.17.2
-         prefix: /usr
-
-Generally this is useful for detecting a small set of commonly-used packages;
-for now this is generally limited to finding build-only dependencies.
-Specific limitations include:
-
-* Packages are not discoverable by default: For a package to be
-  discoverable with ``spack external find``, it needs to add special
-  logic. See :ref:`here <make-package-findable>` for more details.
-* The logic does not search through module files, it can only detect
-  packages with executables defined in ``PATH``; you can help Spack locate
-  externals which use module files by loading any associated modules for
-  packages that you want Spack to know about before running
-  ``spack external find``.
-* Spack does not overwrite existing entries in the package configuration:
-  If there is an external defined for a spec at any configuration scope,
-  then Spack will not add a new external entry (``spack config blame packages``
-  can help locate all external entries).
-
-.. _package-requirements:
-
---------------------
-Package Requirements
---------------------
-
-Spack can be configured to always use certain compilers, package
-versions, and variants during concretization through package
-requirements.
-
-Package requirements are useful when you find yourself repeatedly
-specifying the same constraints on the command line, and wish that
-Spack respects these constraints whether you mention them explicitly
-or not. Another use case is specifying constraints that should apply
-to all root specs in an environment, without having to repeat the
-constraint everywhere.
-
-Apart from that, requirements config is more flexible than constraints
-on the command line, because it can specify constraints on packages
-*when they occur* as a dependency. In contrast, on the command line it
-is not possible to specify constraints on dependencies while also keeping
-those dependencies optional.
-
-.. seealso::
-
-   FAQ: :ref:`Why does Spack pick particular versions and variants? <faq-concretizer-precedence>`
-
-
-^^^^^^^^^^^^^^^^^^^
-Requirements syntax
-^^^^^^^^^^^^^^^^^^^
-
-The package requirements configuration is specified in ``packages.yaml``,
-keyed by package name and expressed using the Spec syntax. In the simplest
-case you can specify attributes that you always want the package to have
-by providing a single spec string to ``require``:
-
-.. code-block:: yaml
-
-   packages:
-     libfabric:
-       require: "@1.13.2"
-
-In the above example, ``libfabric`` will always build with version 1.13.2. If you
-need to compose multiple configuration scopes ``require`` accepts a list of
-strings:
-
-.. code-block:: yaml
-
-   packages:
-     libfabric:
-       require:
-       - "@1.13.2"
-       - "%gcc"
-
-In this case ``libfabric`` will always build with version 1.13.2 **and** using GCC
-as a compiler.
-
-For more complex use cases, require accepts also a list of objects. These objects
-must have either a ``any_of`` or a ``one_of`` field, containing a list of spec strings,
-and they can optionally have a ``when`` and a ``message`` attribute:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       require:
-       - any_of: ["@4.1.5", "%gcc"]
-         message: "in this example only 4.1.5 can build with other compilers"
-
-``any_of`` is a list of specs. One of those specs must be satisfied
-and it is also allowed for the concretized spec to match more than one.
-In the above example, that means you could build ``openmpi@4.1.5%gcc``,
-``openmpi@4.1.5%clang`` or ``openmpi@3.9%gcc``, but
-not ``openmpi@3.9%clang``.
-
-If a custom message is provided, and the requirement is not satisfiable,
-Spack will print the custom error message:
-
-.. code-block:: console
-
-   $ spack spec openmpi@3.9%clang
-   ==> Error: in this example only 4.1.5 can build with other compilers
-
-We could express a similar requirement using the ``when`` attribute:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       require:
-       - any_of: ["%gcc"]
-         when: "@:4.1.4"
-         message: "in this example only 4.1.5 can build with other compilers"
-
-In the example above, if the version turns out to be 4.1.4 or less, we require the compiler to be GCC.
-For readability, Spack also allows a ``spec`` key accepting a string when there is only a single
-constraint:
-
-.. code-block:: yaml
-
-   packages:
-     openmpi:
-       require:
-       - spec: "%gcc"
-         when: "@:4.1.4"
-         message: "in this example only 4.1.5 can build with other compilers"
-
-This code snippet and the one before it are semantically equivalent.
-
-Finally, instead of ``any_of`` you can use ``one_of`` which also takes a list of specs. The final
-concretized spec must match one and only one of them:
-
-.. code-block:: yaml
-
-   packages:
-     mpich:
-       require:
-       - one_of: ["+cuda", "+rocm"]
-
-In the example above, that means you could build ``mpich+cuda`` or ``mpich+rocm`` but not ``mpich+cuda+rocm``.
-
-.. note::
-
-   For ``any_of`` and ``one_of``, the order of specs indicates a
-   preference: items that appear earlier in the list are preferred
-   (note that these preferences can be ignored in favor of others).
-
-.. note::
-
-   When using a conditional requirement, Spack is allowed to actively avoid the triggering
-   condition (the ``when=...`` spec) if that leads to a concrete spec with better scores in
-   the optimization criteria. To check the current optimization criteria and their
-   priorities you can run ``spack solve zlib``.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Setting default requirements
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can also set default requirements for all packages under ``all``
-like this:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require: '%clang'
-
-which means every spec will be required to use ``clang`` as a compiler.
-
-Requirements on variants for all packages are possible too, but note that they
-are only enforced for those packages that define these variants, otherwise they
-are disregarded. For example:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require:
-       - "+shared"
-       - "+cuda"
-
-will just enforce ``+shared`` on ``zlib``, which has a boolean ``shared`` variant but
-no ``cuda`` variant.
-
-Constraints in a single spec literal are always considered as a whole, so in a case like:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require: "+shared +cuda"
-
-the default requirement will be enforced only if a package has both a ``cuda`` and
-a ``shared`` variant, and will never be partially enforced.
-
-Finally, ``all`` represents a *default set of requirements* -
-if there are specific package requirements, then the default requirements
-under ``all`` are disregarded. For example, with a configuration like this:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       require:
-       - 'build_type=Debug'
-       - '%clang'
-     cmake:
-       require:
-       - 'build_type=Debug'
-       - '%gcc'
-
-Spack requires ``cmake`` to use ``gcc`` and all other nodes (including ``cmake``
-dependencies) to use ``clang``. If enforcing ``build_type=Debug`` is needed also
-on ``cmake``, it must be repeated in the specific ``cmake`` requirements.
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Setting requirements on virtual specs
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-A requirement on a virtual spec applies whenever that virtual is present in the DAG.
-This can be useful for fixing which virtual provider you want to use:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       require: 'mvapich2 %gcc'
-
-With the configuration above the only allowed ``mpi`` provider is ``mvapich2 %gcc``.
-
-Requirements on the virtual spec and on the specific provider are both applied, if
-present. For instance with a configuration like:
-
-.. code-block:: yaml
-
-   packages:
-     mpi:
-       require: 'mvapich2 %gcc'
-     mvapich2:
-       require: '~cuda'
-
-you will use ``mvapich2~cuda %gcc`` as an ``mpi`` provider.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Conflicts and strong preferences
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If the semantic of requirements is too strong, you can also express "strong preferences" and "conflicts"
-from configuration files:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       prefer:
-       - '%clang'
-       conflict:
-       - '+shared'
-
-The ``prefer`` and ``conflict`` sections can be used whenever a ``require`` section is allowed.
-The argument is always a list of constraints, and each constraint can be either a simple string,
-or a more complex object:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       conflict:
-       - spec: '%clang'
-         when: 'target=x86_64_v3'
-         message: 'reason why clang cannot be used'
-
-The ``spec`` attribute is mandatory, while both ``when`` and ``message`` are optional.
-
-.. note::
-
-   Requirements allow for expressing both "strong preferences" and "conflicts".
-   The syntax for doing so, though, may not be immediately clear. For
-   instance, if we want to prevent any package from using ``%clang``, we can set:
-
-   .. code-block:: yaml
-
-      packages:
-        all:
-          require:
-          - one_of: ['%clang', '@:']
-
-   Since only one of the requirements must hold, and ``@:`` is always true, the rule above is
-   equivalent to a conflict. For "strong preferences" we need to substitute the ``one_of`` policy
-   with ``any_of``.
-
-
-
-.. _package-preferences:
-
--------------------
-Package Preferences
--------------------
-
-In some cases package requirements can be too strong, and package
-preferences are the better option. Package preferences do not impose
-constraints on packages for particular versions or variants values,
-they rather only set defaults. The concretizer is free to change
-them if it must, due to other constraints, and also prefers reusing
-installed packages over building new ones that are a better match for
-preferences.
-
-.. seealso::
-
-   FAQ: :ref:`Why does Spack pick particular versions and variants? <faq-concretizer-precedence>`
-
-
-Most package preferences (``compilers``, ``target`` and ``providers``)
-can only be set globally under the ``all`` section of ``packages.yaml``:
-
-.. code-block:: yaml
-
-   packages:
-     all:
-       compiler: [gcc@12.2.0, clang@12:, oneapi@2023:]
-       target: [x86_64_v3]
-       providers:
-         mpi: [mvapich2, mpich, openmpi]
-
-These preferences override Spack's default and effectively reorder priorities
-when looking for the best compiler, target or virtual package provider. Each
-preference takes an ordered list of spec constraints, with earlier entries in
-the list being preferred over later entries.
-
-In the example above all packages prefer to be compiled with ``gcc@12.2.0``,
-to target the ``x86_64_v3`` microarchitecture and to use ``mvapich2`` if they
-depend on ``mpi``.
-
-The ``variants`` and ``version`` preferences can be set under
-package specific sections of the ``packages.yaml`` file:
-
-.. code-block:: yaml
-
-   packages:
-     opencv:
-       variants: +debug
-     gperftools:
-       version: [2.2, 2.4, 2.3]
-
-In this case, the preference for ``opencv`` is to build with debug options, while
-``gperftools`` prefers version 2.2 over 2.4.
-
-Any preference can be overwritten on the command line if explicitly requested.
-
-Preferences cannot overcome explicit constraints, as they only set a preferred
-ordering among homogeneous attribute values. Going back to the example, if
-``gperftools@2.3:`` was requested, then Spack will install version 2.4
-since the most preferred version 2.2 is prohibited by the version constraint.
-
-.. _package_permissions:
-
--------------------
-Package Permissions
--------------------
-
-Spack can be configured to assign permissions to the files installed
-by a package.
-
-In the ``packages.yaml`` file under ``permissions``, the attributes
-``read``, ``write``, and ``group`` control the package
-permissions. These attributes can be set per-package, or for all
-packages under ``all``. If permissions are set under ``all`` and for a
-specific package, the package-specific settings take precedence.
-
-The ``read`` and ``write`` attributes take one of ``user``, ``group``,
-and ``world``.
-
-.. code-block:: yaml
-
-  packages:
-    all:
-      permissions:
-        write: group
-        group: spack
-    my_app:
-      permissions:
-        read: group
-        group: my_team
-
-The permissions settings describe the broadest level of access to
-installations of the specified packages. The execute permissions of
-the file are set to the same level as read permissions for those files
-that are executable. The default setting for ``read`` is ``world``,
-and for ``write`` is ``user``. In the example above, installations of
-``my_app`` will be installed with user and group permissions but no
-world permissions, and owned by the group ``my_team``. All other
-packages will be installed with user and group write privileges, and
-world read privileges. Those packages will be owned by the group
-``spack``.
-
-The ``group`` attribute assigns a Unix-style group to a package. All
-files installed by the package will be owned by the assigned group,
-and the sticky group bit will be set on the install prefix and all
-directories inside the install prefix. This will ensure that even
-manually placed files within the install prefix are owned by the
-assigned group. If no group is assigned, Spack will allow the OS
-default behavior to go as expected.
-
-.. _assigning-package-attributes:
-
-----------------------------
-Assigning Package Attributes
-----------------------------
-
-You can assign class-level attributes in the configuration:
-
-.. code-block:: yaml
-
-  packages:
-    mpileaks:
-      package_attributes:
-        # Override existing attributes
-        url: http://www.somewhereelse.com/mpileaks-1.0.tar.gz
-        # ... or add new ones
-        x: 1
-
-Attributes set this way will be accessible to any method executed
-in the package.py file (e.g. the ``install()`` method). Values for these
-attributes may be any value parseable by yaml.
-
-These can only be applied to specific packages, not "all" or
-virtual packages.

 ^^^^^^^^^^^^^^^^^^
 Version comparison
 ^^^^^^^^^^^^^^^^^^
 
-Spack imposes a generic total ordering on the set of versions,
-independently from the package they are associated with.
-
 Most Spack versions are numeric, a tuple of integers; for example,
-``0.1``, ``6.96`` or ``1.2.3.1``. In this very basic case, version
-comparison is lexicographical on the numeric components:
-``1.2 < 1.2.1 < 1.2.2 < 1.10``.
+``0.1``, ``6.96`` or ``1.2.3.1``.  Spack knows how to compare and sort
+numeric versions.
 
-Spack can also supports string components such as ``1.1.1a`` and
-``1.y.0``. String components are considered less than numeric
-components, so ``1.y.0 < 1.0``. This is for consistency with
-`RPM <https://bugzilla.redhat.com/show_bug.cgi?id=50977>`_. String
-components do not have to be separated by dots or any other delimiter.
-So, the contrived version ``1y0`` is identical to ``1.y.0``.
+Some Spack versions involve slight extensions of numeric syntax; for
+example, ``py-sphinx-rtd-theme@=0.1.10a0``.  In this case, numbers are
+always considered to be "newer" than letters.  This is for consistency
+with `RPM <https://bugzilla.redhat.com/show_bug.cgi?id=50977>`_.
 
-Pre-release suffixes also contain string parts, but they are handled
-in a special way. For example ``1.2.3alpha1`` is parsed as a pre-release
-of the version ``1.2.3``. This allows Spack to order it before the
-actual release: ``1.2.3alpha1 < 1.2.3``. Spack supports alpha, beta and
-release candidate suffixes: ``1.2alpha1 < 1.2beta1 < 1.2rc1 < 1.2``. Any
-suffix not recognized as a pre-release is treated as an ordinary
-string component, so ``1.2 < 1.2-mysuffix``.
+Spack versions may also be arbitrary non-numeric strings, for example
+``develop``, ``master``, ``local``.
 
-Finally, there are a few special string components that are considered
-"infinity versions". They include ``develop``, ``main``, ``master``,
-``head``, ``trunk``, and ``stable``. For example: ``1.2 < develop``.
-These are useful for specifying the most recent development version of
-a package (often a moving target like a git branch), without assigning
-a specific version number. Infinity versions are not automatically used when determining the latest version of a package unless explicitly required by another package or user.
-
-More formally, the order on versions is defined as follows. A version
-string is split into a list of components based on delimiters such as
-``.`` and ``-`` and string boundaries. The components are split into
-the **release** and a possible **pre-release** (if the last component
-is numeric and the second to last is a string ``alpha``, ``beta`` or ``rc``).

-Runtime and build time environment variables

-
-Spack provides a few methods to help package authors set up the required environment variables for
-their package. Environment variables typically depend on how the package is used: variables that
-make sense during the build phase may not be needed at runtime, and vice versa. Further, sometimes
-it makes sense to let a dependency set the environment variables for its dependents. To allow all
-this, Spack provides four different methods that can be overridden in a package:

-1. :meth:`setup_build_environment <spack.builder.Builder.setup_build_environment>`
-2. :meth:`setup_run_environment <spack.package_base.PackageBase.setup_run_environment>`

-Notice that ``setup_dependent_run_environment`` can be called multiple times, once for each
-dependent package, whereas ``setup_run_environment`` is called only once for the package itself.
-This means that the former should only be used if the environment variables depend on the dependent
-package, whereas the latter should be used if the environment variables depend only on the package
-itself.
-
---------------------------------
-Setting package module variables
---------------------------------
-
-Apart from modifying environment variables of the dependent package, you can also define Python
-variables to be used by the dependent. This is done by implementing

-the  ``AutotoolsBuilder`` and invoke ``./configure --with-my-feature``.
-
-Dependencies are always specified in the package class. When some dependencies

-usual:

-           depends_on("pkgconfig", type="build")
-
-Very often projects switch from one build system to another, or add support
-for a new build system from a certain version, which means that the choice
-of the build system typically depends on a version range. Those situations can
-be handled by using conditional values in the ``build_system`` directive:
-
-.. code-block:: python
-
-   class Example(CMakePackage, AutotoolsPackage):

-       build_system(

-
-In the example the directive impose a change from ``Autotools`` to ``CMake`` going
-from ``v0.63`` to ``v0.64``.
-
-The ``build_system`` can be used as an ordinary variant, which also means that it can
-be used in ``depends_on`` statements. This can be useful when a package *requires* that
-its dependency has a CMake config file, meaning that the dependent can only build when the
-dependency is built with CMake, and not Autotools. In that case, you can force the choice

-------------------------------
-Specifying License Information
-------------------------------
-
-Most of the software in Spack is open source, and most open source software is released
-under one or more `common open source licenses <https://opensource.org/licenses/>`_.
-Specifying the license that a package is released under in a project's
-`package.py` is good practice. To specify a license, find the `SPDX identifier
-<https://spdx.org/licenses/>`_ for a project and then add it using the license
-directive:
-
-.. code-block:: python
-
-   license("<SPDX Identifier HERE>")
-
-For example, the SPDX ID for the Apache Software License, version 2.0 is ``Apache-2.0``,
-so you'd write:
-
-.. code-block:: python
-
-   license("Apache-2.0")
-
-Or, for a dual-licensed package like Spack, you would use an `SPDX Expression
-<https://spdx.github.io/spdx-spec/v2-draft/SPDX-license-expressions/>`_ with both of its
-licenses:
-
-.. code-block:: python
-
-   license("Apache-2.0 OR MIT")
-
-Note that specifying a license without a when clause makes it apply to all
-versions and variants of the package, which might not actually be the case.
-For example, a project might have switched licenses at some point or have
-certain build configurations that include files that are licensed differently.
-Spack itself used to be under the ``LGPL-2.1`` license, until it was relicensed
-in version ``0.12`` in 2018.
-
-You can specify when a ``license()`` directive applies using with a ``when=``
-clause, just like other directives. For example, to specify that a specific
-license identifier should only apply to versions up to ``0.11``, but another
-license should apply for later versions, you could write:
-
-.. code-block:: python
-
-   license("LGPL-2.1", when="@:0.11")
-   license("Apache-2.0 OR MIT", when="@0.12:")
-
-Note that unlike for most other directives, the ``when=`` constraints in the
-``license()`` directive can't intersect. Spack needs to be able to resolve
-exactly one license identifier expression for any given version. To specify
-*multiple* licenses, use SPDX expressions and operators as above. The operators
-you probably care most about are:
-
-* ``OR``: user chooses one license to adhere to; and
-* ``AND``: user has to adhere to all the licenses.
-
-You may also care about `license exceptions
-<https://spdx.org/licenses/exceptions-index.html>`_ that use the ``WITH`` operator,
-e.g. ``Apache-2.0 WITH LLVM-exception``.
-
-Many of the licenses that are currently in the spack repositories have been
-automatically determined. While this is great for bulk adding license
-information and is most likely correct, there are sometimes edge cases that
-require manual intervention. To determine which licenses are validated and
-which are not, there is the `checked_by` parameter in the license directive:
-
-.. code-block:: python
-
-   license("<license>", when="<when>", checked_by="<github username>")
-
-When you have validated a github license, either when doing so explicitly or
-as part of packaging a new package, please set the `checked_by` parameter
-to your Github username to signal that the license has been manually
-verified.
