I am using 7551P processor and I keep on getting errors when I try to use run the MPI application with more than 8 processors. Could this be the problem of NUMA core settings?
Any help would be appreciated.
Dual CPU boards are the most common in blade server setups.
Qual CPU boxes are uncommon as few need to use more then 256GB of RAM for a workload etc
HPE has made 8 CPU servers but that box was very expensive and it used a custom chipset for Intel
I was asking if I need to do a special configuration settings for AMD EPYC CPU when using MPI. I can only run my MPI application with no more than 8 cores. By the way, I am using 7551P, 32 core, which is single socket processor.
If your app is that limited you may be better off with a CPU like my R5 2400G which is 4 cores and 8 threads and stuff a board is a rack chassis and hook it up the the backplane
generally any CPU cannot do much about the cores, the operating system can to some extent but I have not seen anything in Windows. I have used threads and OpenMP in C++ extensively.
