CPU utilization
Hello.
I am having trouble making use of all the processors available on my workstation. The workstation has 2 sockets, 20 cores and 40 logical processors, running on Windows 10 Enterprise. Now, I run Star CCM by loading the simulation on Parallel on Local Host, Compute Processes : 40, but when I check performance as it is running, only 20 CPUs from node 0 run at max capacity, while the other 20 CPUs from node 1 are barely used(under 5%). Should I be using Microsoft Job Scheduler or some setting to make use of CPUs in node 1? Thank you in advance. Seyong. |

Try using a different MPI. I believe there is a limitation for the default MPI for newer Intel silicon with high core counts.
