[slurm-users] Partition Hold/Release

[Nicolas Sonoda]

Hi Marcus,

Thank you very much for the response.

I set the PriorityTier for my partitions and also set PreemptType=preempt/partition_prio and PreemptMode=SUSPEND,GANG. But the job in the low priority partition does not change it state to SUSPEND. Have any idea?

Following are some information:

slurm.conf:
PreemptType=preempt/partition_prio
PreemptMode=SUSPEND,GANG
NodeName=n[24] Sockets=2 CoresPerSocket=24 ThreadsPerCore=1 RealMemory=185000 State=UNKNOWN
PartitionName=test Nodes=n[24] Default=NO MaxTime=INFINITE State=UP PriorityTier=300 PriorityJobFactor=100 OverSubscribe=FORCE PreemptMode=off AllowGroups=teste
PartitionName=test2 Nodes=n[24] Default=NO MaxTime=INFINITE State=UP PriorityTier=20 PriorityJobFactor=1 OverSubscribe=FORCE PreemptMode=suspend,gang AllowGroups=teste

$ squeue -u vhpc
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
             46003      test     test     vhpc PD       0:00      1 (Resources)
             46002     test2    test2     vhpc  R       0:05      1 n24

Thank you,
Nícolas

Hi Nicolas,


you could use the prioritytier for partitions:


       PriorityTier
              Jobs submitted to a partition with a higher PriorityTier value will be evaluated by the scheduler before pending jobs in a partition with a lower PriorityTier value.  They  will
              also  be  considered  for preemption of running jobs in partition(s) with lower PriorityTier values if PreemptType=preempt/partition_prio.  The value may not exceed 65533.  Also
              see PriorityJobFactor.



Best

Marcus

Hi!

Can I create a partition with a capacity of hold and release jobs when another partition jobs is submited? For example, the partition one and two can hold their jobs when some job of partition three is submited, and after this job completes the partition one and two releases their jobs again.

Thank you.
