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?
Regards,
Mahmood

There is a *ton* of debug output available - would help to know what you are attempting to debug
