[slurm-users] Reserving a GPU

[Christopher Benjamin Coffey]

Can anyone else confirm that it is not possible to reserve a GPU? Seems a bit strange.

Best,
Chris

        I had the same question and put in a support ticket.  I believe the answer is that you cannot.

        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,
