[slurm-users] Limiting the number of CPU

[Henkel, Andreas]

Hi again,

I’m pretty sure that’s not valid since your scontrol Show job shows minmemorypernode mich bigger than 1G.

Best
Andreas

Hi Brian,

thank you for the suggestion.

It appears that my node is in drain state.
I rebooted the node and everything became fine.

However, the QOS still cannot be applied properly.
Do you have any opinion regarding this issue?


$ sacctmgr show qos where Name=normal_compute format=Name,Priority,MaxWal,MaxTRESPU
      Name   Priority     MaxWall     MaxTRESPU
---------- ---------- ----------- -------------
normal_co+         10    00:01:00  cpu=2,mem=1G


when I run the following script:

#!/bin/bash
#SBATCH --job-name=hostname
#sbatch --time=00:50
#sbatch --mem=1M
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --ntasks-per-node=1
#SBATCH --cpus-per-task=1
#SBATCH --nodelist=cn110

srun hostname


It turns out that the QOSMaxMemoryPerUser has been met

$ squeue
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
                88      defq hostname   sukman PD       0:00      1 (QOSMaxMemoryPerUser)



Check QOS defined for user 'sukman':

sacctmgr show user sukman -s

Try to submit a job with "-n 4" only ?
