[slurm-users] GPU Card Reservation?

[Jason Simms]

Hello all,

At least at one point, I understood that it was not particularly possible, or at least not elegant, to provide priority preempt access to a specific GPU card. So, if a node has 4 GPUs, a researcher can preempt as needed one or more of them.

Is this still the case? Or is there a reasonable way to facilitate this?

Warmest regards,

Jason

I believe the 23.11 version of slurm will allow you to reserve specific
cards as part of a Reservation.  That won't do preemption though as a
reservation just takes the card and dedicates it to the user.  I don't
know if a QoS could pull that off, I haven't experimented with it. A
partition would be all or nothing for a node so that would not work.
