-# Archspec (Python bindings)
-
-Archspec aims at providing a standard set of human-understandable labels for
-various aspects of a system architecture  like CPU, network fabrics, etc. and
-APIs to detect, query and compare them.
-
-This project grew out of [Spack](https://spack.io/) and is currently under
-active development. At present it supports APIs to detect and model
-compatibility relationships among different CPU microarchitectures.
-
-## Getting started with development
-
-The `archspec` Python package needs [poetry](https://python-poetry.org/) to
-be installed from VCS sources. The preferred method to install it is via
-its custom installer outside of any virtual environment:
-```console
-$ curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
-```
-You can refer to [Poetry's documentation](https://python-poetry.org/docs/#installation)
-for further details or for other methods to install this tool. You'll also need `tox`
-to run unit test:
-```console
-$ pip install --user tox
-```
-Finally you'll need to clone the repository:
-```console
-$ git clone --recursive https://github.com/archspec/archspec.git
-```
-
-### Running unit tests
-Once you have your environment ready you can run `archspec` unit tests
-using ``tox`` from the root of the repository:
-```console
-$ tox
-  [ ... ]
-  py27: commands succeeded
-  py35: commands succeeded
-  py36: commands succeeded
-  py37: commands succeeded
-  py38: commands succeeded
-  pylint: commands succeeded
-  flake8: commands succeeded
-  black: commands succeeded
-  congratulations :)
-```
-

-Development Notes on Intel Packages
-====================================
-
-These are notes for concepts and development of

-
-For documentation on how to *use* ``IntelPackage``, see

-***************************************************************************
-Prefix differences between Spack-external and Spack-internal installations
-***************************************************************************
-
-
-Problem summary
-~~~~~~~~~~~~~~~~
-
-For Intel packages that were installed external to Spack, ``self.prefix`` will
-be a *component-specific* path (e.g. to an MKL-specific dir hierarchy), whereas
-for a package installed by Spack itself, ``self.prefix`` will be a
-*vendor-level* path that holds one or more components (or parts thereof), and
-must be further qualified down to a particular desired component.
-
-It is possible that a similar conceptual difference is inherent to other
-package families that use a common vendor-style installer.
-
-
-Description
-~~~~~~~~~~~~
-
-Spack makes packages available through two routes, let's call them A and B:
-
-A. Packages pre-installed external to Spack and configured *for* Spack
-B. Packages built and installed *by* Spack.
-
-For a user who is interested in building end-user applications, it should not
-matter through which route any of its dependent packages has been installed.
-Most packages natively support a ``prefix`` concept which unifies the two
-routes just fine.
-
-Intel packages, however, are more complicated because they consist of a number
-of components that are released as a suite of varying extent, like "Intel
-Parallel Studio *Foo* Edition", or subsetted into products like "MKL" or "MPI",
-each of which also contain libraries from other components like the compiler
-runtime and multithreading libraries. For this reason, an Intel package is
-"anchored" during installation at a directory level higher than just the
-user-facing directory that has the conventional hierarchy of ``bin``, ``lib``,
-and others relevant for the end-product.
-
-As a result, internal to Spack, there is a conceptual difference in what
-``self.prefix`` represents for the two routes.
-
-For route A, consider MKL installed outside of Spack. It will likely be one
-product component among other products, at one particular release among others
-that are installed in sibling or cousin directories on the local system.
-Therefore, the path given to Spack in ``packages.yaml`` should be a
-*product-specific and fully version-specific* directory.  E.g., for an
-``intel-mkl`` package, ``self.prefix`` should look like::
-
-  /opt/intel/compilers_and_libraries_2018.1.163/linux/mkl
-
-In this route, the interaction point with the user is encapsulated in an
-environment variable which will be (in pseudo-code)::
-
-    MKLROOT := {self.prefix}
-
-For route B, a Spack-based installation of MKL will be placed in the directory
-given to the ``./install.sh`` script of Intel's package distribution.  This
-directory is taken to be the *vendor*-specific anchor directory, playing the
-same role as the default ``/opt/intel``. In this case, ``self.prefix`` will
-be::
-
-  $SPACK_ROOT/opt/spack/linux-centos6-x86_64/gcc-4.9.3/intel-mkl-2018.1.163-<HASH>
-
-However, now the environment variable will have to be constructed as *several
-directory levels down*::
-
-    MKLROOT := {self.prefix}/compilers_and_libraries_2018.1.163/linux/mkl
-
-A recent post on the Spack mailing list illustrates the confusion when route A
-was taken while route B was the only one that was coded in Spack:
-https://groups.google.com/d/msg/spack/x28qlmqPAys/Ewx6220uAgAJ
-
-
-Solution
-~~~~~~~~~
-
-Introduce a series of functions which will return the appropriate
-directories, regardless of whether the Intel package has been installed
-external or internal to Spack:

-Analysis of directory layouts

-
-Let's look at some sample directory layouts, using ``ls -lF``,
-but focusing on names and symlinks only.

-
-Spack-external installation of Intel-MPI 2018
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-For MPI, the layout is slightly different than MKL. The prefix will have to
-include an architecture directory (typically ``intel64``), which then contains
-bin/, lib/, ..., all without further architecture branching.  The environment
-variable ``I_MPI_ROOT`` from the API documentation, however, must be the
-package's top directory, not including the architecture.
-
-FIXME: For MANPATH, need the parent dir.
-
-::
-
-  $ ls -lF /opt/intel/compilers_and_libraries_2018.1.163/linux/mpi/
-  bin64 -> intel64/bin/
-  etc64 -> intel64/etc/
-  include64 -> intel64/include/
-  lib64 -> intel64/lib/
-
-  benchmarks/
-  binding/
-  intel64/
-  man/
-  test/
-
-The package contains an MPI-2019 preview; Curiously, its release notes contain
-the tag: "File structure clean-up." I could not find further documentation on
-this, however, so it is unclear what, if any, changes will make it to release.
-
-https://software.intel.com/en-us/articles/restoring-legacy-path-structure-on-intel-mpi-library-2019

-
-Spack-external installation of Intel Parallel Studio 2018
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This is the main product bundle that I actually downloaded and installed on my
-system.  Its nominal installation directory mostly holds merely symlinks
-to components installed in sibling dirs::

-  psxevars.sh		 -> ./bin/psxevars.sh*
-  bin/            - *vars.*sh scripts + sshconnectivity.exp ONLY
-
-  licensing/
-  uninstall*
-
-The only relevant regular files are ``*vars.*sh``, but those also just churn
-through the subordinate vars files of the components.
-
-Installation model
-~~~~~~~~~~~~~~~~~~~~
-
-Intel packages come with an ``install.sh`` script that is normally run
-interactively (in either text or GUI mode) but can run unattended with a
-``--silent <file>`` option, which is of course what Spack uses.
-
-Format of configuration file
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The configuration file is conventionally called ``silent.cfg`` and has a simple
-``token=value`` syntax.  Before using the configuration file, the installer
-calls ``<staging_dir>/pset/check.awk`` to validate it. Example paths to the
-validator are::
-
-      .../l_mkl_2018.1.163/pset/check.awk .
-      .../parallel_studio_xe_2018_update1_cluster_edition/pset/check.awk
-
-The tokens that are accepted in the configuration file vary between packages.
-Tokens not supported for a given package **will cause the installer to stop
-and fail.** This is particularly relevant for license-related tokens, which are
-accepted only for packages that actually require a license.
-

-Details for licensing tokens
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Quoted from
-https://software.intel.com/en-us/articles/configuration-file-format,
-for reference:
-
-[ed. note: As of 2018-05, the page incorrectly references ``ACTIVATION``, which
-was used only until about 2012; this is corrected to ``ACTIVATION_TYPE`` here.]
-
-    ...
-
-    ``ACTIVATION_TYPE=exist_lic``
-       This directive tells the install program to look for an existing
-       license during the install process.  This is the preferred method for
-       silent installs.  Take the time to register your serial number and get
-       a license file (see below).  Having a license file on the system
-       simplifies the process.  In addition, as an administrator it is good
-       practice to know WHERE your licenses are saved on your system.
-       License files are plain text files with a .lic extension.  By default
-       these are saved in /opt/intel/licenses which is searched by default.
-       If you save your license elsewhere, perhaps under an NFS folder, set
-       environment variable **INTEL_LICENSE_FILE** to the full path to your
-       license file prior to starting the installation or use the
-       configuration file directive ``ACTIVATION_LICENSE_FILE`` to specify the
-       full pathname to the license file.
-    
-       Options for ``ACTIVATION_TYPE`` are ``{ exist_lic, license_file, server_lic,
-       serial_number, trial_lic }``
-    
-    ``exist_lic``
-       directs the installer to search for a valid license on the server.
-       Searches will utilize the environment variable **INTEL_LICENSE_FILE**,
-       search the default license directory /opt/intel/licenses, or use the
-       ``ACTIVATION_LICENSE_FILE`` directive to find a valid license file.
-    
-    ``license_file``
-       is similar to exist_lic but directs the installer to use
-       ``ACTIVATION_LICENSE_FILE`` to find the license file.
-    
-    ``server_lic``
-       is similar to exist_lic and exist_lic but directs the installer that
-       this is a client installation and a floating license server will be
-       contacted to active the product.  This option will contact your
-       floating license server on your network to retrieve the license
-       information.  BEFORE using this option make sure your client is
-       correctly set up for your network including all networking, routing,
-       name service, and firewall configuration.  Insure that your client has
-       direct access to your floating license server and that firewalls are
-       set up to allow TCP/IP access for the 2 license server ports.
-       server_lic will use **INTEL_LICENSE_FILE** containing a port@host format
-       OR a client license file.  The formats for these are described here
-       https://software.intel.com/en-us/articles/licensing-setting-up-the-client-floating-license
-    
-    ``serial_number``
-       directs the installer to use directive ``ACTIVATION_SERIAL_NUMBER`` for
-       activation.  This method will require the installer to contact an
-       external Intel activation server over the Internet to confirm your
-       serial number.  Due to user and company firewalls, this method is more
-       complex and hence error prone of the available activation methods.  We
-       highly recommend using a license file or license server for activation
-       instead.
-    
-    ``trial_lic``
-       is used only if you do not have an existing license and intend to
-       temporarily evaluate the compiler.  This method creates a temporary
-       trial license in Trusted Storage on your system.

-vars files
-*******************
-
-Intel's product packages contain a number of shell initialization files let's call them vars files.
-
-There are three kinds:
-
-#. Component-specific vars files, such as `mklvars` or `tbbvars`.
-#. Toplevel vars files such as "psxevars". They will scan for all
-   component-specific vars files associated with the product, and source them
-   if found.
-#. Symbolic links to either of them. Links may appear under a different name
-   for backward compatibility.
-
-At present, IntelPackage class is only concerned with the toplevel vars files,
-generally found in the product's toplevel bin/ directory.
-
-For reference, here is an overview of the names and locations of the vars files
-in the 2018 product releases, as seen for Spack-native installation. NB: May be
-incomplete as some components may have been omitted during installation.
-
-Names of vars files seen::
-

-MPI linkage
-********************
-
-
-Library selection
-~~~~~~~~~~~~~~~~~~~~~
-
-In the Spack code so far, the library selections for MPI are:
-
-::
-
-        libnames = ['libmpifort', 'libmpi']
-        if 'cxx' in self.spec.last_query.extra_parameters:
-            libnames = ['libmpicxx'] + libnames
-        return find_libraries(libnames,
-                              root=self.component_lib_dir('mpi'),
-                              shared=True, recursive=False)
-
-The problem is that there are multiple library versions under ``component_lib_dir``::
-
-    $ cd $I_MPI_ROOT 
-    $ find . -name libmpi.so | sort
-    ./intel64/lib/debug/libmpi.so
-    ./intel64/lib/debug_mt/libmpi.so
-    ./intel64/lib/libmpi.so
-    ./intel64/lib/release/libmpi.so
-    ./intel64/lib/release_mt/libmpi.so
-
-"mt" refers to multi-threading, not in the explicit sense but in the sense of being thread-safe::
-
-    $ mpiifort -help | grep mt
-       -mt_mpi         link the thread safe version of the Intel(R) MPI Library
-
-Well, why should we not inspect what the canonical script does?  The wrapper
-has its own hardcoded "prefix=..." and can thus tell us what it will do, from a
-*wiped environment* no less!::
-
-    $ env - intel64/bin/mpiicc -show hello.c | ld-unwrap-args 
-    icc 'hello.c' \
-        -I/opt/intel/compilers_and_libraries_2018.1.163/linux/mpi/intel64/include \
-        -L/opt/intel/compilers_and_libraries_2018.1.163/linux/mpi/intel64/lib/release_mt \
-        -L/opt/intel/compilers_and_libraries_2018.1.163/linux/mpi/intel64/lib \
-        -Xlinker --enable-new-dtags \
-        -Xlinker -rpath=/opt/intel/compilers_and_libraries_2018.1.163/linux/mpi/intel64/lib/release_mt \
-        -Xlinker -rpath=/opt/intel/compilers_and_libraries_2018.1.163/linux/mpi/intel64/lib \
-        -Xlinker -rpath=/opt/intel/mpi-rt/2017.0.0/intel64/lib/release_mt \
-        -Xlinker -rpath=/opt/intel/mpi-rt/2017.0.0/intel64/lib \
-        -lmpifort \
-        -lmpi \
-        -lmpigi \
-        -ldl \
-        -lrt \
-        -lpthread
-
-
-MPI Wrapper options
-~~~~~~~~~~~~~~~~~~~~~
-
-For reference, here's the wrapper's builtin help output::
-
-    $ mpiifort -help
-    Simple script to compile and/or link MPI programs.
-    Usage: mpiifort [options] <files>
-    ----------------------------------------------------------------------------
-    The following options are supported:
-       -fc=<name> | -f90=<name>
-                       specify a FORTRAN compiler name: i.e. -fc=ifort
-       -echo           print the scripts during their execution
-       -show           show command lines without real calling
-       -config=<name>  specify a configuration file: i.e. -config=ifort for mpif90-ifort.conf file
-       -v              print version info of mpiifort and its native compiler
-       -profile=<name> specify a profile configuration file (an MPI profiling
-                       library): i.e. -profile=myprofile for the myprofile.cfg file.
-                       As a special case, lib<name>.so or lib<name>.a may be used
-                       if the library is found
-       -check_mpi      link against the Intel(R) Trace Collector (-profile=vtmc).
-       -static_mpi     link the Intel(R) MPI Library statically
-       -mt_mpi         link the thread safe version of the Intel(R) MPI Library
-       -ilp64          link the ILP64 support of the Intel(R) MPI Library
-       -no_ilp64       disable ILP64 support explicitly
-       -fast           the same as -static_mpi + pass -fast option to a compiler.
-       -t or -trace
-                       link against the Intel(R) Trace Collector
-       -trace-imbalance
-                       link against the Intel(R) Trace Collector imbalance library
-                       (-profile=vtim)
-       -dynamic_log    link against the Intel(R) Trace Collector dynamically
-       -static         use static linkage method
-       -nostrip        turn off the debug information stripping during static linking
-       -O              enable optimization
-       -link_mpi=<name>
-                       link against the specified version of the Intel(R) MPI Library
-    All other options will be passed to the compiler without changing.
-    ----------------------------------------------------------------------------
-    The following environment variables are used:
-       I_MPI_ROOT      the Intel(R) MPI Library installation directory path
-       I_MPI_F90 or MPICH_F90
-                       the path/name of the underlying compiler to be used
-       I_MPI_FC_PROFILE or I_MPI_F90_PROFILE or MPIF90_PROFILE
-                       the name of profile file (without extension)
-       I_MPI_COMPILER_CONFIG_DIR
-                       the folder which contains configuration files *.conf
-       I_MPI_TRACE_PROFILE
-                       specify a default profile for the -trace option
-       I_MPI_CHECK_PROFILE
-                       specify a default profile for the -check_mpi option
-       I_MPI_CHECK_COMPILER
-                       enable compiler setup checks
-       I_MPI_LINK      specify the version of the Intel(R) MPI Library
-       I_MPI_DEBUG_INFO_STRIP
-                       turn on/off the debug information stripping during static linking
-       I_MPI_FCFLAGS
-                       special flags needed for compilation
-       I_MPI_LDFLAGS 
-                       special flags needed for linking
-    ----------------------------------------------------------------------------

-Side Note: MPI version divergence in 2015 release
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The package `intel-parallel-studio@cluster.2015.6` contains both a full MPI
-development version in `$prefix/impi` and an MPI Runtime under the
-`composer_xe*` suite directory. Curiously, these have *different versions*,
-with a release date nearly 1 year apart::
-
-    $ $SPACK_ROOT/...uaxaw7/impi/5.0.3.049/intel64/bin/mpiexec --version
-    Intel(R) MPI Library for Linux* OS, Version 5.0 Update 3 Build 20150804 (build id: 12452)

-    Copyright (C) 2003-2014, Intel Corporation. All rights reserved.
-
-I'm not sure what to make of it.

-macOS support
-**************
-
-- On macOS, the Spack methods here only include support to integrate an
-  externally installed MKL.
-
-- URLs in child packages will be Linux-specific; macOS download packages
