Cgroups don’t take effect until the job has started;. It’s a bit clunky, but
you can do things like this
inspect_job_cgroup_memory ()
{
set -- $(squeue "$@" -O JobId,UserName | sed -n '$p');
sudo -u $2 srun --pty --jobid "$1" bash -c 'cat
/sys/fs/cgroup/memory/slurm/uid_$(id
-u)/job_${SLURM_JOB_ID}/memory.usage_in_bytes'
}
There are lots of other files in that filesystem hierarchy to report on other
things like cpusets, IO etc.
Obviously if you’re not the admin of the system, you can only do this for your
own jobs, and then you don’t need the sudo part of the shell function.

Hello,
Thanks for your answers. I will try now!! One more question: is there any way
