Hi Marcus and Kevin, I'm sorry, I forgot to set DefMemPerCPU on my partitions so my preempt was not working.
But after I set, the preempt worked fine and my jobs with low priority can suspend. Thank you very much!

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?

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 Am 06.03.2023 um 19:33 schrieb Nicolas Sonoda: 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.
