On BlueBrain5, installing software and creating modules requires only the Spack module:
$ module load spack
To modify packages and update deployment related files, clone this repository in addition. The following commands are a good way to get started:
$ module load spack unstable git
$ git clone -c feature.manyFiles=true git@github.com:BlueBrain/spack.git
$ . spack/share/spack/setup-env.sh
To be fully independent of the module, export the system configuration path, and make sure that this is done every time before using Spack:
$ export SPACK_SYSTEM_CONFIG_PATH=/gpfs/bbp.cscs.ch/ssd/apps/bsd/config
$ export SPACK_USER_CACHE_PATH=$HOME/spack_install
Note that the git clone should be executed in a subdirectory of the home
directory on GPFS.
The project directories are backed by a slower GPFS setup, and using a
Spack installation from the project directories will result in a big
performance penalty.
By loading the provided Spack module and sourcing the local Spack
installation afterwards,
software and modules will be installed into ${HOME}/spack_install.
To customise this, use the following commands:
$ spack config add config:install_tree:root:${HOME}/my_software
$ spack config add modules:default:roots:tcl:${HOME}/my_modules
To generate a module for the package my_package,
modify the include list with the following command:
$ spack config add "modules:default:tcl:include:[my_package]"
And use
$ spack module tcl refresh my_package
To generate or update the module.
Note that this may have unintended consequences and is not a supported configuration.
