Hi!
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
