Re: [slurm-dev] Small jobs waitingThanks Carles, It’s work! I have change the Schedule to Backfill and my small jobs is running allocating the IDLE nodes.
Thanks again!!! From: Carles Fenoy Sent: Monday, April 29, 2013 10:40 AM To: slurm-dev Subject: [slurm-dev] Re: Small jobs waiting Hola Alfonso, Do you have backfilling enabled? Do all the jobs have a timelimit set? Backfilling can only work if the jobs have a timelimit set, either by specifying it of using the partition max time limit. If you do not have backfilling enabled, jobs will follow the priority order. So I will recomend checking the backfilling and the job timelimit and see if that is the reason for the smaller jobs to not start.

I have a cluster with 15 nodes and slurm multifactor policy: # JOB PRIORITY PriorityType=priority/multifactor PriorityFavorSmall=YES PriorityUsageResetPeriod=NONE PriorityWeightAge=1000 PriorityWeightFairshare=1000 PriorityWeightJobSize=10000 PriorityWeightPartition=1000 PriorityDecayHalfLife=0 PriorityMaxAge=7-0 PriorityWeightQOS=1 EnforcePartLimits=YES PreemptMode=Checkpoint PreemptType=preempt/qos If I have 2 jobs running (left 13 nodes no allocated) and I submit a job than request 14 nodes it will wait for free resources. But during this waiting I submit another job than only request 1 node, the new job will wait becouse has less priority than the 14-requested-job, althought I have nodes in IDLE state. For example (squeue): 248790 test job3 user3 PD 0:00 1 (Priority) 249991 test job3 user3 PD 0:00 1 (Priority) 250096 test job3 user3 PD 0:00 1 (Priority) 242962 test job2 user2 PD 0:00 14 (Resources) 242879 test job1 user1 R 2-23:34:46 1 bc-p3-01 242930 test job1 user1 R 2-23:34:46 1 bc-p4-01 And my sinfo: PARTITION AVAIL TIMELIMIT NODES STATE NODELIST test* up infinite 2 alloc bc-p3-01,bc-p4-01 test* up infinite 12 idle bc-p10-01,bc-p11-01,bc-p12-01,bc-p13-01,bc-p14-01,bc-p15-01,bc-p16-01,bc-p17-01,bc-p18-01,bc-p5-01,bc-p6-01,bc-p9-01 Have I a erroneous configuration?
