I am trying the backfill scheduler without success.
I just want to test it with the most simple configuration possible* (see
slurm.conf at the end).
7 homogenous nodes, 12 CPU per node
I submit three jobs and the last should be backfilled, but ... :
$ sbatch --nice=0 -N 5 -c 12 --time-min="09:00" --time="10:00" ~/slurm/job.sh
Submitted batch job 65574
$ sbatch --nice=0 -N 5 -c 12 --time-min="09:00" --time="10:00" ~/slurm/job.sh
Submitted batch job 65575
sbatch --nice=0 -N 1 -c 12 --time-min="00:40" --time="01:00" ~/slurm/job.sh
Submitted batch job 65576
$ squeue
JOBID PARTITION NAME USER ST TIME NODES
NODELIST(REASON)
65575 prod.q job.sh hummelm PD 0:00 5 (Resources)
65576 prod.q job.sh hummelm PD 0:00 1 (Priority)
65574 prod.q job.sh hummelm R 7:54 5 OGSE[1-5]
I hope someone here can show me the error I've made, thks.
