I'm afraid not. Before your post, I had never heard of Rapid IO.

That being said, Open MPI is based on plugins, so someone could write a plugin for Radio IO support, if they were so inclined.

Open MPI supports a wide variety of networks:

    - OpenFabrics: InfiniBand and iWARP
    - Myrinet: GM and MX
    - Qlogic PSM
    - Portals
    - Quadrics Elan
    - Shared memory
    - TCP
    - SCTP
    - uDAPL
    - Loopback (send-to-self)
