Hello Arielle,

I don't have a full answer, but here is a start:

Yes, you first need at least "AccountingStorageEnforce=associations,limits" (and qos is you want to use it) so that the limits you set are enforced (see https://slurm.schedmd.com/resource_limits.html)

Then you can set limits for each user eg with "sacctmgr modify account where account=<account> set MaxJobs=50" to set the max number of jobs for each of the users of this account (replace <account> as needed). Then maybe set it for a single user: "sacctmgr modify account where account=<account> user=<user> set MaxJobs=500".

You can check what is set with "sacctmgr show associations", and remove what has been set by setting it to -1.

I hope this helps,
Colas

Hi,

slurm is installed in a minimal configuration for a cluster of 3000cores/170 nodes.We have 4 partitions, one for each type of nodes; each partition is available for all users. We want to prevent each user from taking more than 1000 cores running on up to 50 jobs on all the cluster, and I'm looking for guidance on how we should do so.

I have already read a lot of documentation about it , i tried but i have no result

- Below a list of some config parameters :

    ClusterName=cluster
    # Accounting.
    AccountingStorageType=accounting_storage/slurmdbd
    AccountingStorageUser=slurm
    #AccountingStorageEnforce=qos,limits
    #AccountingStoragePass=
    #AccountingStoragePort=
    EnforcePartLimits=YES
    # SCHEDULING
    SchedulerType=sched/backfill
    # Consumable Resource
    SelectType=select/cons_res
    SelectTypeParameters=CR_Core

- about the config in the slurmDB , there are not many things, only account root and only user root

sacctmgr show account
   Account                Descr                  Org
---------- -------------------- --------------------
      root default root account                 root

I have tried : sacctmgr modify cluster set GrpTRES=cpu=1040

but it does not work !

What is wrong ?


Did we need to uncomment the parameter AccountingStorageEnforce ?

Did we need to define all the users ?

Can someone show the way to proceed?

Thanks for your help

A Willm
