I sent a problem to the list but didn't receive any reply. In short, we found
that when we run openmpi+openfoam program on a node (in a diskless cluster), there is a huge IO operations caused by openmpi. When we run openmpi+openfoam on the server, there is no problem. When we run openfoam directly on the node, there is also no problem. Now I am looking for some verbose/debug outputs from openmpi which shows the activity of it (in particular IO messages for example opening file1 or closing file2...). Can I extract such messages?
