Log in to the compute node and run 'slurmd -C' to get Slurm's viewpoint:


e.g.

[root at cwc001 ~]# slurmd -C
NodeName=cwc001 CPUs=12 Boards=1 SocketsPerBoard=2 CoresPerSocket=6 ThreadsPerCore=1 RealMemory=36138 TmpDisk=92680

Subject: Re: [slurm-users] Multithreads config

I have included in slurm.conf the following (based on web configurator). i have 64 cpus, not 63.

NodeName=obelix CPUs=64 RealMemory=480000  CoresPerSocket=16 ThreadsPerCore=1 state=UNKNOWN

>sinfo -Nl


sinfo: error: NodeNames=obelix CPUs=64 doesn't match Sockets*CoresPerSocket*ThreadsPerCore (16), resetting CPUs

A proper configuration that shows basic quantities of effort went into
reading the documentation.

RTFM and use the configurator:
https://slurm.schedmd.com/configurator.html

You failed to define a nodename and apart from that just defining a node
isn't enough -- you need at least a partition that uses that node...
