Subject: [OMPI users] opal_mutex_lock(): Resource deadlock avoided
From: Ake Sandgren (ake.sandgren_at_[hidden])

We have a code that trips on this fairly often. I've seen cases where it
works but mostly it gets stuck here.

The actual mpi call is call mpi_file_open(...)

I'm currently just wondering if there has been other reports on/anyone
have seen deadlock in mpi-io parts of the code or if this most likely
caused by our setup.

openmpi version is 1.4.2 (fails with 1.3.3 too)
Filesystem used is GPFS

openmpi built with mpi-threads but without progress-threads
