You might want to check that Open MPI processes are actually running on the remote nodes -- check with ps if you see any "orted" or other MPI-related processes (e.g., your processes). Do you have any TCP firewall software running between the nodes? If so, you'll need to disable it (at least for Open MPI jobs). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
