As using this GPU resource increase I would like to manage this resource with Gres to avoid usage conflict. But at this time my setup do not works as I can reach a GPU without reserving it:

srun -n 1 -p tenibre-gpu ./a.out

can use a GPU even if the reservation do not specify this resource (checked with running nvidia-smi  on the node). "tenibre-gpu" is a slurm partition with only this gpu node.

I think what you're looking for is the ConstrainDevices parameter in cgroup.conf. See here: - https://slurm.schedmd.com/archive/slurm-20.11.7/cgroup.conf.html Best, -- Roberto Polverelli Monti HPC System Engineer Do IT Now | https://doitnowgroup.com
