Hello,

I have a testing partition with only a node. That server has 12 CPUs (it’s a very old server) (2 sockets, 6 cores per socket, 1 thread per core). That partition, called “test.q” only has that node, so by default, partition test.q has 12 CPUs (all from testing node). However, now I would like to decrease that CPU number from 12 to 4, for example. “slurmd -C” returns “CPUs=12 Boards=1 SocketsPerBoard=2 CoresPerSocket=6 ThreadsPerCore=1” as I have said to you before and if in slurm.conf I configure partition in this way “PartitionName=test.q Nodes=test-node MaxTime=10:00 State=UP AllocNodes=clus-login MaxCPUsPerNode=4”, partition continues accepting jobs with 12 CPUs.

Is it any wrong in my configuration? How could I get my purpose?

Thanks.
