Hello,I haven't really seen this discussed anywhere, but maybe I didn't look in the right places.
After our upgrade from 21.08 to 23.02 we had users complaining about srun not using the specified --cpus-per-task given in sbatch-directives. The changelog of 22.05 mentions this change and explains the need to set the Environment variable SRUN_CPUS_PER_TASK. The environment variable SLURM_CPUS_PER_TASK will be set by the sbatch-directive, but is ignored by srun.
Does anyone know why this behaviour was changed? Imo the expectation that an sbatch-directive is the default for the whole job-script is reasonable.
Is there a config option to reenable the old behaviour, or do we have to find a workaround with a job_submit script or a profile.d script? If so, have any of you already implemented such a workaround?
