Hello everybody, we have a shared memory cluster, which has 512 cores (64 sockets * 8 cores) and we had set the following in the Slurm configuration: NodeName=venus Sockets=64 CoresPerSocket=8 ThreadsPerCore=1 State=UNKNOWN CPUSpecList=0-23 RealMemory=8000000
When I create a reservation over 368 cores, I only can use 344 cores within that reservation. That’s the reason why I guess, the CPUSpecList causes the problem. Also, I removed the CPUSpecList and everything works fine! We currently run Slurm 16.05.2, but I think, we still had the problem in older versions too. Could you please tell me, what I’m doing wrong? Kind regards, Danny
