Hi Deepak,

The Intel MPI 4.1 Version is quite outdated and not supported anymore.

In the latest Intel MPI 2019 update 6 library, we have a new OFI provider for InfiniBand called MLX, that will also be selected out of box. This provider will also run on multi-rail installations with the default configuration.

Best regards,

Michael
