Site-specific configuration
===================================
.. _temp-space:
Temporary space
----------------------------
.. deprecated::
This will be moved to configuration files.
By default, Spack will try to do all of its building in temporary
space. There are two main reasons for this. First, Spack is designed
to run out of a user's home directory, and on may systems the home
directory is network mounted and potentially not a very fast
filesystem. We create build stages in a temporary directory to avoid
this. Second, many systems impose quotas on home directories, and
``/tmp`` or similar directories often have more available space. This
helps conserve space for installations in users' home directories.
You can customize temporary directories by editing
``lib/spack/spack/__init__.py``. Specifically, find this part of the file:
.. code-block:: python
# Whether to build in tmp space or directly in the stage_path.
# If this is true, then spack will make stage directories in
# a tmp filesystem, and it will symlink them into stage_path.
use_tmp_stage = True
# Locations to use for staging and building, in order of preference
# Use a %u to add a username to the stage paths here, in case this
# is a shared filesystem. Spack will use the first of these paths
# that it can create.
tmp_dirs = ['/nfs/tmp2/%u/spack-stage',
'/var/tmp/%u/spack-stage',
'/tmp/%u/spack-stage']
The ``use_tmp_stage`` variable controls whether Spack builds
**directly** inside the ``var/spack/`` directory. Normally, Spack
will try to find a temporary directory for a build, then it *symlinks*
that temporary directory into ``var/spack/`` so that you can keep
track of what temporary directories Spack is using.
The ``tmp_dirs`` variable is a list of paths Spack should search when
trying to find a temporary directory. They can optionally contain a
``%u``, which will substitute the current user's name into the path.
The list is searched in order, and Spack will create a temporary stage
in the first directory it finds to which it has write access. Add
more elements to the list to indicate where your own site's temporary
directory is.

Mirrors

packages, you can edit this file and reorder the sections. Spack will
search the topmost mirror first and the bottom-most mirror last.
