HashDist is a deprecated Python package for managing reproducible source-based installations of large software stacks. The core idea is based on the cryptographic hashing approach developed more fully in Nix. HashDist was developed quickly to make the approach feasible on platforms in the DoD High Performance Computing Modernization Program. HashDist can still be used to build the software stack for Proteus but interested users should look to similar community-supported tools such as spack and conda-build, which incorporate many of the ideas in HashDist.
