------------------------------------------------------------------------
mpiexec has exited due to process rank 2 with PID 32631 on
node orca.cora.nwra.com exiting improperly. There are two reasons this could 
occu

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it wa
for all processes to call "init". By rule, if one process calls "init"
then ALL processes must call "init" prior to termination

2. this process called "init", but exited without calling "finaliz
By rule, all processes that call "init" MUST call "finalize" prior
exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to
terminated by signals sent by mpiexec (as reported here)
------------------------------------------------------------------------

It appears to work fine with mpich2.  Has anyone else come across this?

Thanks,

  Orion
