Welcome to the hpc-spack wiki!

This collects some of the initial design decisions and considerations we had when creating spacksites.

Also the method for using personal Spack installs on our clusters without use of spacksites.

Other site setups

Spack has a repo at https://github.com/spack/spack-configs

User-level

• ORNL, installing own user packages with a base central environment and chained Spack instances https://docs.olcf.ornl.gov/software/spack_env/summit_spack_env.html

Additional

• E4S as mentioned above uses Spack and provides a build cache and containers. Attempts to put together an interoperable set of packages. "The Extreme-Scale Scientific Software Stack (E4S) is a community effort supported by the Exascale Computing Project (ECP) to provide an ecosystem of open source software packages for developing, deploying and running scientific applications on HPC platforms."
