Dear all,
i suspect something weird with slurm where your specification "#SBATCH
--ntasks-per-node=8" may be misinterpreted by slurm
or at least by humans :-)
Could you check when you launch your job that when it runs you don't see
a lot or CPU usage ?
What happens if you do not specify the ntasks-per-node ?
I have went though your slurm conf file but I suspect slurm understands
"nbgpu * nbtasks", and may split them ...
Often I use "htop" in addition of nvidia-smi, because you should only
see 8 cpu usage and 8 gpu usage, the "exclusive" mode for the GPU should
not be a problem...
HTH,
Stéphane
