Hi Lydia, I can't help with the IB issue, but I am interested in the issue running over MX. I found a ticket from 2007 regarding Gadget-2. The last set of mails indicated that the app was running. You have had a few tickets since, but none mentioned Gadget. Can you give me more details about the hang that you experienced? I have a couple of ideas that we could investigate (one in Open-MPI and the other in MX). Scott
