     Hello,

    I have tried running MPI with Open MPI but it wouldn't work so I
    switched to MPICH2. My code complies fine in Windows using Visual
    Studio 2010 but when I go to invoke mpiexec -n 2 TEST.exe it runs for
    some time then crashes with the error:

    Error while connecting to host, A connection attempt failed because
    the connected party did not properly respond after a period of time,
    or established connection failed because connected host has failed to
    respond. (10060)

    Hi,

    This is likely a firewall issue - you should make sure that smpd.exe and your TEST.exe are both allowed through the firewall.

    Note that MPICH no longer supports Windows, and I'd recommend using a supported MPI implementation (e.g. MS-MPI).  Moving from MPICH to MS-MPI should be straight forward, as MS-MPI is derived from MPICH.
