2022-11-14: Upgrade to SLURM 22.05.5
SLURM has been upgraded from 21.08.8-2 to 22.05.5, a major new version with additional functionality, security fixes and also breaking changes.
Highlighted change in this release that may impact your jobs: srun will no longer read in
SLURM_CPUS_PER_TASK. This means you will explicitly have to specify
-c) in your srun calls, or set the new
SRUN_CPUS_PER_TASK environment variable get the correct result.
For a full list of changes since SLURM 21.08.8-2 please see the SchedMD SLURM release notes. Note that not all updates may apply to MeluXina, as the job launcher daemon on the compute nodes is not the upstream
2023-01-15: 2022.1 software stack set as default
The 2022.1 software stack announced and installed on MeluXina in mid November 2022 is now the default stack in on the compute nodes. For details into the new tools available vs the previous release please see the notice below.
You can still use the previous production software stack by using
module load env/release/2021.3 in your job scripts.
myquota tool (v0.3.1) for monitoring the usage of your resource allocations is now available on compute nodes through the module system, and loaded by default.
