Hi Alex IBM Platform MPI was discontinued on April 30, 2020.
At the AnsysEM2020R1 release, the IBM Platform MPI option was replaced by MS MPI.

Are you distributing via AnsoftRSMService or a Windows Server 2016 w/ HPC addon scheduler?
-- AnsoftRSMService would use Intel MPI. In this situation, you would install Intel MPI on each computer and register each user's credentials. MS MPI is not a valid option in this situation.
-- Windows HPC scheduler can use either Intel or MS MPI. However, you would most likely use MS MPI as it is installed with the scheduler addon. MS MPI authentication is done automatically via AD.
thanks
