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".

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