Hello!

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?


Thanks in advance!!!!
