Hello, I'm coming back on this problem. Because after I read again the documentation and do other tests I have the same problem with the preemption..
My partition : PartitionName=OPA Nodes=hpc-node[1-2] Priority=100 Default=No PreemptMode=OFF PartitionName=LDEV Nodes=hpc-node[1-2] Priority=50 Default=Yes PreemptMode=SUSPEND PartitionName=LOP Nodes=hpc-node[1] Priority=50 Default=Yes PreemptMode=SUSPEND PartitionName=LALL Nodes=hpc-node[2] Priority=50 Default=Yes PreemptMode=SUSPEND In my mind, if I submit a job on each partitions LOP and LALL with 16 cpus requested. For me I can't see a job submit on LDEV running ! Am I right or not ? I don't have this problem with GANG sheduling. I try with keyword FastSchedule=1 , Shared=[NO,FORCE:1] without succes. A part of my slurm.conf # SCHEDULING SchedulerType=sched/backfill #RESOURCES SelectType=select/cons_res SelectTypeParameters=CR_CPU_Memory FastSchedule=0 #PREEMPTION PreemptMode=GANG,SUSPEND PreemptType=preempt/partition_prio I don't see my mistake. Thx David
