[slurm-users] Re: Can't specify multiple partitions when submitting GPU jobs

Perhaps some of the partition's default (maybe even implicit) are to blame?

Update: I also noticed that specifying -ntasks makes a difference when --gpus is present.

if I have two partitions a100 and h100 that both have free GPUs:

✅ h100 specified first in -p: works sbatch -p h100,a100 --gpus h100:1 script.sh

❌ h100 specified second: doesn't work sbatch -p a100,h100 --gpus h100:1 script.sh

Adding --ntasks: works ✅ sbatch -p a100,h100 --gpus h100:1 --ntasks 1 script.sh
