The past year was full of momentum for the High Performance Software Foundation and HPSF projects 🚀

As the neutral hub for open source high performance software, check out what we accomplished in 2025 & what’s on the horizon for 2026 ➡️ hpsf.io/blog/2026/ch...

🎉 Starting the year with speed improvements!

Recent work on Modules significantly reduces the time spent evaluating large numbers of modulefiles. If performance matters in your environment, check out the details:

This track is not limited to the Modules project — talks about Lmod or any other module implementation are very welcome. If your work touches environment modules and you think others can learn from it, we’d love to hear from you!

See you in Chicago this March!

🚀 Modules 5.6 is out!
Packed with new features:
✨ spider sub-command
🔗 require_via for module hierarchy
👀 Always show hidden modules
⚠️ Warnings on eval issues
🆘 Simplified help message
🔄 Newline support in env vars
📦 Declare provided elements

🔎 Full details: modules.readthedocs.io/en/latest/MI...

✨ New in upcoming *Modules v5.6*: the `require_via` config option!
It lets you define dependency links between *via* modules and modulefiles in the paths they enable — bringing full support for the *module hierarchy* mechanism.
🔗 Learn more: modules.readthedocs.io/en/latest/MI...

Coming in Modules v5.6: the new `spider` sub-command! 🕷️
It lists all available modules—both in enabled modulepaths and those discovered recursively.
Learn more: modules.readthedocs.io/en/latest/MI...

🚀 Coming in Modules v5.6: new provide command lets modules declare additional elements they offer (as aliases)!
Details & examples 👉 modules.readthedocs.io/en/latest/MI...

New feature introduced in upcoming Modules v5.6: ability to always see hidden modules, by adding the "hidden" item to the output configuration options. See modules.readthedocs.io/en/latest/MI...

Do you know the "envml" command? Like "env", it runs a program in a modified environment, but here environment is modified by Modules. "envml" is available since Modules 4.0 and it is freshly documented in its own man page 📖: modules.readthedocs.io/en/latest/en...

Next Modules version (5.6) will add the ability to define environment variable whose value contains newline character modules.readthedocs.io/en/latest/MI...

🔧 Just updated: Environment Modules docs now include a deep dive into alternative implementations, with a specific focus on Lmod. Useful to learn the differences between the two implementations.

📚 modules.readthedocs.io/en/latest/ot...

Next version (5.6) will introduce the "module-help" modulefile command to provide a simpler way to define modulefile help message. See modules.readthedocs.io/en/latest/MI...

Next version (5.6) will come with new modulefile command: "module-warn". This command defines a warning message to print when loading specified modulefiles. See modules.readthedocs.io/en/latest/MI...
