how to configure Intel MPI on EPYC 7742

Hello, I am using a server with AMD EPYC 7742 CPU to run HFSS simulation. Compared with my normal intel cpu server, this server runs very slowly, and I cannot use two processors at the same time when scanning parameters. But two CPUs can be called on the intel server. And when I installed the intel MPI, it was prompted that it was not an intel architecture. Forcing the installation will not get good performance. I tried to ask the supplier for help, but apparently they didn’t know anything and couldn’t find an easy way on Google. I tried to check the manual of amd "high performance computing: tuning guide for epyc 7002series processors" but it seems mainly for linux, and i am using windows server 2019, so please help me, thank you!20211205153841.png
