According to SLURM QOS document, one can specify a Quality of Service
(QOS) for each job submitted to SLURM. So one can use different QOSs in
order to send jobs to different partitions. But there should be a
machanism that force the user to use only the related QOS while sending
jobs to the partitions. I mean that, if I have two partitions (and qos )
like PartitionHigh (QOShigh) and PartitionLow (QOSlow), the user
should be able to send jobs to PartitionHigh olnly using the QOSHigh.
Using QOSHigh on the partition PartitionLow somehow should be
forbidden. I couldn't find such a mechanism on SLURM documents.
Furthermore, is there a mechanism to limit gres usage like maxGPU per
group,user or job which may be defined in QOS definition (or
account/user/partition definition)?

Using one partition with multiple QOS is probably the simplest way to
potentially satisfy your needs. See

Hi all,
I ‘am new user to SLUMR and I want to know : What is the best way to
limit the maximum number of CPU used by each user in one partition
but not in others ? By Association and/or QOS ?
I have two partitions:
scontrol show partition
PartitionName=Def
AllocNodes=ALL AllowGroups=ALL Default=YES
DefaultTime=NONE DisableRootJobs=NO GraceTime=0 Hidden=NO
MaxNodes=1 MaxTime=5-00:00:00 MinNodes=1
Nodes=dr[01-26]
Priority=10000 RootOnly=NO ReqResv=NO Shared=NO PreemptMode=OFF
State=UP TotalCPUs=416 TotalNodes=26 DefMemPerNode=UNLIMITED
MaxMemPerNode=UNLIMITED
PartitionName=Long
AllocNodes=ALL AllowGroups=ALL Default=NO
DefaultTime=NONE DisableRootJobs=NO GraceTime=0 Hidden=NO
MaxNodes=1 MaxTime=21-00:00:00 MinNodes=1
Nodes=dr[01-26]
Priority=5000 RootOnly=NO ReqResv=NO Shared=NO PreemptMode=OFF
State=UP TotalCPUs=416 TotalNodes=26 DefMemPerNode=UNLIMITED
MaxMemPerNode=UNLIMITED
I would like to limit the maximum number of CPU used by user on
‘long’ partition, e.g. 32, but not on the ‘def’ partition.
Thanks in advance,
Sébastien,
