Hi;

You can find the Definitions of Socket, Core, & Thread at:

https://slurm.schedmd.com/mc_support.html

Your status:

CPUs=COREs=Sockets*CoresPerSocket=1*4=4

Threads=COREs*ThreadsPerCore=4*2=8

Hi,

Here is my node information. I am confused with the terminology w.r.t CPU vs CORE.

NodeName=hpathuri-linux CPUs=8 RealMemory=15833 Sockets=1 CoresPerSocket=4 ThreadsPerCore=2 State=UNKNOWN.

I am unable to schedule more than 4 tasks without over subscribing even through my configuration looks like this:

SchedulerType=sched/backfill

#SchedulerPort=7321

SelectType=select/cons_res

SelectTypeParameters=CR_Core

PreemptMode=suspend,GANG

Could help clarify what is going on?

I was expecting to schedule 8 tasks.

Thanks
