Hi,
I have some questions about partition priority values defined in
slurm.conf file. I use:
PriorityType=priority/multifactor
PriorityDecayHalfLife=0
PriorityUsageResetPeriod=NONE
PriorityFavorSmall=YES
PriorityMaxAge=14-0
PriorityWeightAge=1000
PriorityWeightFairshare=0
PriorityWeightJobSize=1000
PriorityWeightPartition=10000
PriorityWeightQOS=100000
PreemptType=preempt/partition_prio
PreemptMode=SUSPEND,GANG
I have same nodes on two partition with different partition priority
values, all other values are the same for these two partions..
let say :
PartitionName=lowprio Nodes=node[1-10] Default=no State=UP
Shared=NO Priority=1000
PartitionName=hiprio Nodes=node[1-10] Default=no State=UP
Shared=NO Priority=2000
I am sending the same jobs to every partitions,
PRIORITY JOBID ACCOUNT PARTIT CPUS NODELIST(REASON
13976 4052106 user hiprio 16 1 (Resources)
12976 4052108 user lowpri 16 1 (Resources)
and then increase the job priorities of jobs in lower-priority
partition with "scontrol update jobid= .." to a value more than the
ones in higher priority partition.
PRIORITY JOBID ACCOUNT PARTIT CPUS NODELIST(REASON
13976 4052106 user hiprio 16 1 (Resources)
16000 4052108 user lowpri 16 1 (Resources)
After I make the nodes idle, normally I expect the the jobs has higher
priority should be run before the lower-priority jobs, but in realty
jobs which has lower priority values ( jobs at higger priority
partition) starts more early..
PRIORITY JOBID ACCOUNT PARTIT CPUS NODELIST(REASON
13976 4052106 user hiprio 16 1 node1
16000 4052108 user lowpri 16 1 (Resources)
I was thinking that partition priorities are used only to determine the
job priority. Do I miss something or made some wrongs? I have searched
hr list archive, there were similar questions for slurm-2.6 but there
was no relevant answer.. we use slurm-13.12.0
