On Slurm on Atos AD complex was updated to version 22.05. Since AD has been the default cluster with hpc-login and hpc-batch being aliases for nodes on AD complex.
The same version of Slurm 22.05 has been installed on AA and AB complexes and will be installed on AC complex on .
One change in the new Slurm version impacts all batch jobs setting the number of OMP threads with directive:
#SBATCH --cpus-per-task |
Following recommendation from the official release note:
Srun will no longer read in SLURM_CPUS_PER_TASK. This means you will implicitly have to specify --cpus-per-task on your srun calls, or set the new SRUN_CPUS_PER_TASK env var to accomplish the same thing. |
we strongly suggest to all Atos HPC users adjusting their job scripts by specifying number of OMP threads as an option with "srun" command:
srun --cpus-per-task |
${SLURM_CPUS_PER_TASK:
