Hello, we're operating a Slurm 15.08.8 cluster in PreemptType=preempt/qos (and PreemptMode=CANCEL) mode to provide a partition for cycle-harvesting tasks (which in turn may be preempted by another one via QOS); Shared=EXCLUSIVE is set for all partitions.
I've received a request to split off a number of nodes for gang-scheduling now. The slurm.conf man page suggests that this would (only?) be possible for PreemptType=preempt/partition-prio (by setting PreemptMode=SUSPEND,GANG for the special partition, which would then also be set to Shared=YES:n). Is this limitation real? Is there a way around it? Thanks, Steffen
