Hi everyone,<br><br>When I try one example from <a href="http://beige.ucs.indiana.edu/I590/node62.html">http://beige.ucs.indiana.edu/I590/node62.html</a>, I got the following error message as below. In the MPI cluster, there are two hosts. If I run the two processes on just one host, everything works fine. But if I run two processes on the two-host cluster, the following error happens. I think the two hosts just can't send/receive message to each other, but I don't know how to resolve this.<br>
<br>Thanks in advance!<br><br clear="all">xxxx@query:~/MPI$ mpiexec -n 2 -f machinefile ./GreetMaster<br>Fatal error in PMPI_Bcast: Other MPI error, error stack:<br>PMPI_Bcast(1430).......................: MPI_Bcast(buf=0x7fff13114cb0, count=8192, MPI_CHAR, root=0, MPI_COMM_WORLD) failed<br>
