MPI Vendor and MPI Version

For HFSS, HFSS 3D Layout, Q3D Extractor, Maxwell, and Icepak design types:

These settings may be used to specify the MPI Vendor and Version for distribution via MPI.

Go to the Options tab of the HPC and Analysis Options dialog box, and select the design type. Then you can select the MPI Vendor and MPI version.

MPI Vendor

The default MPI Vendor is "Intel". On Linux, "Intel" is the only supported MPI vendor. On Windows, both "Intel" and "Microsoft" are supported MPI vendor options. For jobs distributed to multiple hosts, the "Microsoft" MPI Vendor is only supported when running as a Windows HPC job.

MPI Version

If only a single MPI Version is supported for the selected MPI Vendor, then the MPI Version option is ignored. Multiple versions are only supported for Intel MPI, as follows:

• The value "Default" indicates that the default Intel MPI version should be used. This is Intel MPI 2021 in most cases.

• The value "2018" indicates that Intel MPI 2018 should be used.

• The value "2021" indicates that Intel MPI 2021 should be used.
