Hello all, As usual, I have a super basic question, so thank you for your patience. I want to verify the correct syntax to configure a GPU for priority preempt access via a QOS, much like we are currently doing for a specified number of cores. When I have created a QOS in the past, I've so far only been concerned about priority access to a subset of CPUs, so this is my simple example command once I've created a new QOS:
sacctmgr modify qos <qosname> set GrpCPUs=24 Looking at other examples (such as https://help.rc.ufl.edu/doc/Account_and_QOS_limits_under_SLURM), it seems that GrpTRES is used to define priority access to a GPU (but then, they also have an entry for cpu as a GrpTRES as well, which I don't, so maybe I need to add that??). Is it as simple as something like this?: sacctmgr modify qos <qosname> set GrpTRES=gres/gpu=1 Or, do I *also* need to add the cpu to the GrpTRES?: sacctmgr modify qos <qosname> set GrpTRES=cpu=24,gres/gpu=1 GrpCPUs=24 The syntax is a little unclear from examples in the official documentation, and I guess this is also a question about the difference between GrpCPUs and GrpTRES.
