Hi,
I am running LES using pimpleFoam on 20 physical cores. Mesh size is around 7 millions. In the Task Manager window, I see 20 "pimpleFoam -parallel" processes, each using 2.4GiB of memory. Does that mean the total memory usage is 2.4 * 20 = 48GB? This looked too much for such a run, but also 2.4GiB total memory usage sounds too small. 65 png So which one should I consider? Best regards, Huseyin Specs: 24-core AMD Threadripper 3960x CPU 64GiB of memory OS: Xubuntu 20.04 |
