Open Stack

Reza:

You should be able to run MPI programs across OpenStack instances as long
as your setup is configured so that instances are allowed to communicate
with each other over the fixed IPs, and your security group settings allow
traffic across the ports that your MPI implementation is using.

(OpenStack doesn't provide a distributed file system, so if you need to do
MPI-IO stuff you have to add the shared file system part yourself)

Are you able to ping/ssh from one instance to another on the fixed IPs?
