Luke,
I don't have access to exactly the same OS like you describe, but I
was able to run your example (using the same compilation flags as
you) on the following environments:
- 32 bits Intel Redhat Nahant 2
- 32 bits Debian testing/unstable
- 64 bits MAC OS X
I even run the Netpipe benchmark with success on the same systems.
However, there was an issue with our internal list management that
was showing up [mostly] for the shared memory device. It's fixed now
on SVN (from revision 8749).
Please update you Open MPI copy (the changes are not yet in the
nightly build so you have to checkout via SVN) and try again.
Thanks,
george.

If we compile openmpi with support for posix threads (./configure

threads=posix,
it works fine. We've tried this with both 1.0.1 and 1.0.2a3 on a
CentOS
release 4.2 install (CentOS is the same as Redhat, built from the
same sources,
just without the trademarked name and the support), and on a Debian
unstable install. Does anyone have any ideas on getting openmpi to
work with posix thread support?
