MVAPICH2 - supported network types

Can MVAPICH2 be installed on a normal ethernet network other than InfiniBand or other HPC networking technology?

Solution

  • The very first line on the MVAPICH2 web site reads:

    MVAPICH2 (MPI-3 over OpenFabrics-IB, OpenFabrics-iWARP, PSM, uDAPL and TCP/IP)

    Then from the list of supported interfaces:

    • TCP/IP-CH3: The standard TCP/IP interface (provided by MPICH2) to work with a range of network adapters supporting TCP/IP interface. This interface can be used with IPoIB (TCP/IP over InfiniBand network) support of InfiniBand also. However, it will not deliver good performance/ scalability as compared to the other interfaces.

    Therefore - yes.
