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) Connect on sock (host=BAHR83M5Z8.resource.ds.bah.com, port=8676) failed, exhause d all end points Unable to connect to 'BAHR83M5Z8.resource.ds.bah.com:8676', sock error: Error = -1 Thanks regard _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
