slurm AllocMem always 0

  • 772

When running jobs with --mem or --mem-per-cpu the AllocMem stays 0 when the job is running.

# scontrol -V
slurm 2.6.5
# sbatch --mem=2500 tmp.sh 
Submitted batch job 25
# squeue 
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
                25      main   tmp.sh     root  R       0:05      1 w1
# scontrol -o show node w1 | awk '{ print $1, $13, $14}'
NodeName=w1 RealMemory=3764 AllocMem=0

Why is that the case?

I would expect there to be a number corresponding to my mem requirement.

    You have to specify that you want to use Memory as a Consumable Resource. Check in the Slurm config file that you have SelectTypeParameters=CR_CPU_Memory or something stating Memory and that the select plugin that you are using is the SelectType=select/cons_res.
