[slurm-users] Reserving a GPU

[Christopher Benjamin Coffey]

Hi,

I can't figure out how one would create a reservation to reserve a gres unit, such as a gpu. The man page doesn't really say that gres is supported for a reservation, but it does say tres is supported. Yet, I can't seem to figure out how one could specify a gpu with tres. I've tried:


scontrol create reservation starttime=2018-11-10T08:00:00 user=root duration=14-00:00:00 tres=gpu/tesla=1
scontrol create reservation starttime=2018-11-10T08:00:00 user=root duration=14-00:00:00 gres=gpu:tesla:1

Is it not possible to reserve a single gpu? Our gpus are requested normally in jobs like " --gres=gpu:tesla:1". I'd rather not reserve an entire node and thus reserve all of the gpus in it. Thanks!

Best,
Chris
