[slurm-users] 19.05 and GPUs vs GRES

[Christopher Benjamin Coffey]

Hi,

Excuse me if this has been explained somewhere, I did some searching. With 19.05, is there any reason to have gres.conf on the GPU nodes? Is slurm smart enough to enumerate the /dev/nvidia* devices? We are moving to 19.05 shortly, any gotchas with GRES and GPUs? Also, I'm guessing now, there is no reason for users to request "--gres:gpu" type stuff anymore and instead use: --gpus=n ?

Thank you!

Best,
Chris
