I'm not intimately familiar with boost++ -- you might want to try the "hello world" and "ring" example programs in the OMPI examples/ directory as a baseline.
Additionally, try executing a non-MPI program such as "hostname" to verify that your remote connectivity is working. For example: $ mpirun --host localhost,name_of_distant_machine hostname You should see the output of both "hostname" executions. If you don't, check the process table and see if OMPI is trying to ssh or rsh over to the remote host, and see what is happening on the remote host. E.g., is that rsh or ssh being blocked? Or is it actually executing on the remote machine and hanging? Or ...? Ensure that you have the same version of OMPI installed on both machines and that both are in your default search PATH for non-interactive logins. Once you get something like "hostname" to work, it's much more likely that an MPI application will also work.
