[Michael Neff]

Hi Juergen,

Thanks for the hint,
I tried to set it to "no" as well but the result was the same.

Best regards,
Michael

Hi Michael,

not sure if this is the root cause of your problem, but SchedMD recommends to set TaskAffinity to "no" in cgroup.conf when using both, task/affinity and task/cgroup, together for TaskPlugin in slurm.conf (see the NOTE for TaskPlugin in slurm.conf).

Best regards
Juergen Salk
