Hi, I have a very simple computing farm on a single PC with AMD Ryzen 7950X (2x16 cores).
I have configured my slurm to use up to 25 CPUs: NodeName=palmer CPUs=25 RealMemory=40000 State=UNKNOWN # Boards=1 SocketsPerBoard=1 CoresPerSocket=16 ThreadsPerCore=2 PartitionName=main Nodes=ALL Default=YES MaxTime=INFINITE State=UP But using htop I see that with all 25 jobs running I use max 16 cores. It seems that like * 6 jobs are using 100% of CPU * 20 jobs use 50% CPU each I use slurm 24.05.2, but I am pretty sure in the past when using I think one of 22.x version, the jobs distribution was like 25 CPUs for 25 jobs with 100% each. Is there anything I can do in the configuration of my farm to have better utilisation of CPU cores? Right now like half of them is not really used. Regards, Rafał
