Ok, good -- glad you got it tracked down. A few tips to keep in mind: - http://www.open-mpi.org/faq/?category=tcp#tcp-selection (you've probably already seen this, but I bring it up just for reference) - http://www.open-mpi.org/faq/?category=tcp#tcp-routability-1.3 - Make sure that all your eth devices are on different subnets.
