[Dave Goodell]

Does the "examples/cpi" program from the MPICH2 build directory work correctly for you when you run it on multiple nodes?

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.
