	I just did some simple tests with 8 processors (2 nodes and
4 threads each) -- it worked for me. Can you send more specifics?
Your config_cache.xml file, namelist, and commands you are using
to invoke the executable (environment variables, and poe command line),
would be helpful in reproducing the problem. Also any specifics on
the machine you are running on might be useful, the machinename,
compiler version, and OS version.
