You can set a partition QoS which specifies a minimum. We have such a qos on
our large-gpu partition; we don’t want people scheduling small stuff to it, so
we have this qos:
$ sacctmgr show qos large-gpu --json | jq '.QOS[] | { name: .name, min_limits:
.limits.min }'
{
"name": "large-gpu",
"min_limits": {
"priority_threshold": {
"set": false,
"infinite": true,
"number": 0
},
"tres": {
"per": {
"job": [
{
"type": "cpu",
"name": "",
"id": 1,
"count": 32
},
{
"type": "mem",
"name": "",
"id": 2,
"count": 262144
},
{
"type": "gres",
"name": "gpu",
"id": 1002,
"count": 3
}
]
}
}
}
}
i.e. the user has to request 32 cores and at least 3 GPUs. If I try to
allocate less I get an error:
$ salloc -p large-gpu --gres=gpu:1 -c 32 --mem 256G
salloc: error: QOSMinGRES
salloc: error: Job submit/allocate failed: Job violates accounting/QOS policy
(job submit limit, user's size and/or time limits)

Subject: [slurm-users] Minimum cpu cores per node partition level configuration
Dear All,
I need to configure the slurm so the user must take a certain minimum number of
CPU cores for a particular partition(not system-wide). Otherwise, the job must
not run.
Any suggestions will be highly appreciated.
With Thanks and Regards
