Hi, all
I want to configure generic consumable resources(gpu) and confirm that the
resources
are assigned to jobs on each node.
I executed the following settings.
o gres.conf
Name=gpu File=/dev/tty[0-3] CPUs=[0-24]
Name=gpu File=/dev/tty[4-7] CPUs=[25-47]
o slurm.conf
TaskPlugin=task/affinity,task/cgroup
　GresTypes=gpu
　NodeName=sl02-c00[1-2] Gres=gpu:2
o cgroup.conf
CgroupAutomount=yes
ConstrainCores=yes
ConstrainDevices=yes
Then I submitted a sleep job with the gpu resource specified.
$ cat gresgpu.sh
#!/bin/bash
#SBATCH -J gresgpu # Job name
#SBATCH --gres=gpu:2
#SBATCH -o job.%j.out # Name of stdout output file (%j expands to jobId)
prun sleep 60
$
Return value of ReqGres was 0.
I don't know why it return value of ReqGres is 0.
$ sbatch gresgpu.sh
Submitted batch job 72
$ squeue -l
