[slurm-users] slurm conf with single machine with multi cores.

[Le Biot, Pierre-Marie]

Hello David,

So linuxcluster is the Head node and also a Compute node ?

Is slurmd running ?

What does /var/log/slurm/slurmd.log say ?

Regards,
Pierre-Marie Le Biot

Hi,
I have updated the slurm.conf as follows:

SelectType=select/cons_res
SelectTypeParameters=CR_CPU
NodeName=linuxcluster CPUs=2
PartitionName=testq Nodes=linuxcluster Default=YES MaxTime=INFINITE State=UP

Still get testq node in down status ??? Any idea ?

Below log from db and controller:

12 Sockets? Certainly not... 12 Cores per socket, yes.
(IIRC CPUS shouldn't be specified if the detailed topology is given.
You may try CPUs=12 and drop the details.)

                           ^^ typo?

Cheers,
