Hi, I have run two scripts that takes 2 nodes and 8 tasks per node. First script runs with "--distribution=block:block" and second with "--distribution=cyclic:block".
As far as I understand, in the first case, with "--distribution=block:block", job has been executed in this way (and I think it is OK): JobNode[0] Socket[0] Core[0] is allocated JobNode[0] Socket[0] Core[1] is allocated JobNode[0] Socket[0] Core[2] is allocated JobNode[0] Socket[0] Core[3] is allocated JobNode[0] Socket[0] Core[4] is allocated JobNode[0] Socket[0] Core[5] is allocated JobNode[0] Socket[1] Core[0] is allocated JobNode[0] Socket[1] Core[1] is allocated JobNode[1] Socket[0] Core[0] is allocated JobNode[1] Socket[0] Core[1] is allocated JobNode[1] Socket[0] Core[2] is allocated JobNode[1] Socket[0] Core[3] is allocated JobNode[1] Socket[0] Core[4] is allocated JobNode[1] Socket[0] Core[5] is allocated JobNode[1] Socket[1] Core[0] is allocated JobNode[1] Socket[1] Core[1] is allocated But, in the second case, with "--distribution=cyclic:block", I assumed that job should have been executed in this way: JobNode[0] Socket[0] Core[0] is allocated JobNode[1] Socket[0] Core[0] is allocated JobNode[0] Socket[0] Core[1] is allocated JobNode[1] Socket[0] Core[1] is allocated JobNode[0] Socket[0] Core[2] is allocated JobNode[1] Socket[0] Core[2] is allocated JobNode[0] Socket[1] Core[3] is allocated JobNode[1] Socket[1] Core[3] is allocated JobNode[0] Socket[0] Core[4] is allocated JobNode[1] Socket[0] Core[4] is allocated JobNode[0] Socket[0] Core[5] is allocated JobNode[1] Socket[0] Core[5] is allocated JobNode[0] Socket[1] Core[0] is allocated JobNode[1] Socket[1] Core[0] is allocated JobNode[0] Socket[1] Core[1] is allocated JobNode[1] Socket[1] Core[1] is allocated but job has run in this other way (well, exactly, the same way that in the first execution): JobNode[0] Socket[0] Core[0] is allocated JobNode[0] Socket[0] Core[1] is allocated JobNode[0] Socket[0] Core[2] is allocated JobNode[0] Socket[0] Core[3] is allocated JobNode[0] Socket[0] Core[4] is allocated JobNode[0] Socket[0] Core[5] is allocated JobNode[0] Socket[1] Core[0] is allocated JobNode[0] Socket[1] Core[1] is allocated JobNode[1] Socket[0] Core[0] is allocated JobNode[1] Socket[0] Core[1] is allocated JobNode[1] Socket[0] Core[2] is allocated JobNode[1] Socket[0] Core[3] is allocated JobNode[1] Socket[0] Core[4] is allocated JobNode[1] Socket[0] Core[5] is allocated JobNode[1] Socket[1] Core[0] is allocated JobNode[1] Socket[1] Core[1] is allocated What have I done wrong? My SLURM server has enabled these parameters and flags: TaskPlugin=task/cgroup,task/none,task/affinity DebugFlags=CPU_Bind,Backfill,BackfillMap,SelectType,Steps,TraceJobs SchedulerType=sched/backfill SelectType=select/cons_res SelectTypeParameters=CR_Core Thanks.
