For me I can't see a job submit on LDEV running ! Uh? That's really unclear to me... Sequence of ops as I understand it: 1) You submit a job to LOP -> runs on hpc-node1, prio=50 2) You submit a job to LALL - > runs on hpc-node2, prio=50 3) You submit a job to LDEV
IIUC, the third job gets *queued*, since LDEV have the same prio as LOP and LALL. If you want the third job to preempt the other two, you have to change partitions priorities. > Am I right or not ?
