2.1. Changed

2.1.1. Default PMIx used by slurm : upgrade from v4 to v5

pmix is a library used by both Slurm and OpenMPI.

To ensure optimal performance when running MPI on GLiCID, it is recommended that you use the same version throughout. You may therefore need to recompile older programs (Further instructions to follow)

2.1.2. InfiniBand drivers

New drivers for the InfiniBand network, may require to compile again MPI codes for benefit from the upgrade.

2.1.3. Slurm upgrade from 25.05 to 25.11

Guix users who have a version of slurm in their user profile (because it is required when using srun within an sbatch) must update it by running guix pull and guix upgrade. The recommended version of Slurm to include in the profile is slurm-glicid-client.

2.1.4. GPFS Nautilus Scratch performance

The performance of /scratch/nautilus should improve significantly, especially with small files.
