[slurm-users] Re: slurmstepd: error: task_g_set_affinity: Operation not permitted

I believe I have solved this. I changed the configuration to replace:

TaskPlugin=task/affinity

with:

TaskPlugin=task/none

In my case, the login node, the head node, and all of the compute nodes are running in their own containers. And docker compose is used to run all of those containers to create a containerized Slurm cluster running on a single physical host. So, I think the "TaskPlugin=task/none" setting is required.

If anyone has any other recommendations, please let me know.
