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?

There is a *ton* of debug output available - would help to know what you are attempting to debug
Dear all,
Is there any way to run openmpi in debug or verbose mode? Is there any log for openmpi run?
