You don't need to run "mpd&" any more. (Hydra doesn't need it.) First see if you can run cpi with multiple processes on a single machine.

> 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
