Hi Jeff,
Thanks. I moved over to MPICH.
Best, Doug.

Ah, that makes more sense.
Yes, if you're trying to run with two different MPI implementations, you'll
have to recompile / re-link your application (Open MPI and MPICH are not ABI
compatible, and your executable may still be linked against MPICH libraries
when you launch with Open MPI's mpirun
I _think_ what the user is saying is that their "hello world" program is
returning rank=0 for all procs when started with mpirun, but not when started
with MPICH's mpiexec.hydra.
The most likely problem is that your "hello" program wasn't built against OMPI
- are you trying to run the same bina
Are you asking a question about MPICH? If so, I think you should probably ask
on their mailing lists -- they're an entirely different project from Open MPI.
Also, I think you mean "processes", not "threads".
