Hey all, I'm new to MPI so if anything doesn't make sense let me know and
I'll do my best to clarify. I'm attempting to set up MPI on an Amazon EC2
machine. I've gone through and followed the instructions in the instruction
manual but whenever I try to run one of the built in examples
(examples/cpi), the call simply hangs. Below is some information about my
system, my MPI set up and the output returned from mpiexec. Right now i'm
not even trying to run anything on a cluster, I simply want to run an MPI
application on one machine. Let me know what other information I can furnish
to help troubleshoot this problem. Thanks in advance for any help. Mike
1) First I ran mpd& to start the process manager
2) mpiexec -info yields the following information

3) Next I run mpiexec -verbose -profile -n 1
/usr/local/mpich2-1.4rc2/examples/cpi the follow is output and then the
program just hangs
