Back to the future: modules for Guix packages (2022)
Summary
Guix-Modules is a new tool that generates Environment Modules files from Guix packages, allowing HPC users to leverage Guix's reproducible software environments with their familiar `module` command interface. This bridges the gap between traditional HPC environment management and Guix's declarative, reproducible approach.
- Guix-Modules generates standard Environment Modules files from Guix packages, integrating Guix into existing HPC workflows.
- It enables reproducible software environments for Modules users by embedding Guix channel and transformation data in module files.
- Sysadmins can use `guix module create` to deploy curated, version-controlled sets of modules, with rollback capabilities.
- Package transformation options like `--tune` for CPU micro-architecture optimization are supported and recorded in provenance data.
HPC sysadmins can now provide highly reproducible and customizable software environments to their users, who can continue using the familiar `module` command, addressing long-standing issues with environment consistency.
