[Message part 1 (text/plain, inline)]

Enables support for the Process Management Interface for Exascale which is used e.g. by Slurm for the management communication and coordination of MPI processes.

This allows e.g. to run guix-created container on JSC Juwels cluster with native performance.

Nice.

Out of curiosity, does the cluster run Guix natively or are you using
‘guix pack’?

I added this to the comment in the code, tweaked the commit log, and
committed.

Thank you!

Hi Ludo,

thanks for committing!

The JSC clusters don't run Guix natively but with the patch I can run 'guix pack' created containers with Apptainer with full interconnect perfomance! Thank you for all your work in this regard! Next up is to test the same container on other HPC platforms (already successfully tested on our in-house cluster EVE).

Sincerely,
Lars

Excellent, good to hear!

Cool, let me know how it goes (we’re also using the same MPI on a range
of clusters in France).

Also next: getting sysadmins to consider installing Guix?  :-)

Thanks,
Ludo’.
