hi there
i'm pretty new to slurm and trying to learn my way through it's many
configurations. my config looks like:
SchedulerType=sched/backfill
PriorityType=priority/multifactor
PriorityWeightAge=10000
PriorityWeightFairshare=10000
PriorityWeightJobSize=5000
PriorityWeightPartition=10000
PriorityWeightQOS=10000
and partitions:
# Node Configurations
NodeName=nodeb[01-10]n[01-05] NodeAddr=nodeb[01-10]n[01-05] CPUs=8
RealMemory=95000 TmpDisk=1700000
PartitionName=part1 Nodes=nodeb[01-10]n[01-05] LLN=YES Default=YES
MaxTime=INFINITE State=Up
NodeName=nodeb[01-10]n[06-46] NodeAddr=nodeb[01-10]n[06-46] CPUs=8
RealMemory=95000 TmpDisk=1700000
PartitionName=part1b Nodes=nodeb[01-10]n[06-46] MaxTime=INFINITE State=Up
NodeName=nodeb[01-10]n[47-48] NodeAddr=nodeb[01-10]n[47-48] CPUs=36
RealMemory=190000 TmpDisk=3500000
PartitionName=part2 Nodes=nodeb[01-10]n[47-48] MaxTime=INFINITE State=Up
NodeName=nodeb12n[01-04] NodeAddr=nodeb12n[01-04] CPUs=8 RealMemory=380000
TmpDisk=5600000
PartitionName=part3 Nodes=nodeb12n[01-04] LLN=YES MaxTime=INFINITE State=Up
PartitionName=part3b Nodes=nodeb12n[01-04] LLN=YES MaxTime=INFINITE State=Up
i'm trying to distribute jobs in partitions evenly per account. that is,
for a given partition if I have jobs queued for accounts A and B I expect
the partition to be split approximately 50/50 between those two accounts
(no matter how the other partitions look like).
but things are not working as I expect and as I can tell fairshare is been
calculated for the entire cluster and not per partition.
sample output of `sshare -lm":
Account User Partition RawShares NormShares

cpu=0,mem=0,energy=0,node=0,b
etc.
as you can see the partition column is not been populated so I guess that's
my problem. i am having a hard time to fix it so any tip would be
appreciated.
thank you.
side note: part3 and part3b are identical because I need jobs to be split
evenly between those two partitions. if one of them has no jobs than the
other partition gets all the machines. I have no clue how to do that but
that's a subject for a future email.
