[mpich-discuss] Fatal error in PMPI_Bcast:

[Fujun Liu]

Hi everyone,

When I try one example from http://beige.ucs.indiana.edu/I590/node62.html, 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.

Thanks in advance!
