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.Saludos,Carles FenoyBarcelona Supercomputing Center On Mon, Apr 29, 2013 at 10:25 AM, Alfonso Pardo <[email protected]> wrote: Hello!

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?
