What version of Open MPI are you using? I see that particular error listed in the "rmgr" part of the code base, not the "pls" part of the code base in the current release (1.2.4). Meaning: I'm guessing that the fact that this help message is not found in your version has been fixed in a later version.

As George pointed out, the real issue is that the "mpitest1" executable was not found when OMPI tried to run it. Do you have mpitest1 available on all nodes where you tried to run it? (e.g., via NFS or some global filesystem)

Hello Brock,

I renamed the whole file as mpitest1.c and issued the following command

mpicc mpitest1.c -o mpitest1
mpirun -np 4 ./mpitest1

then i got the following output:

Sorry!  You were supposed to get help about:
  argv0-not-accessible
from the file:
  help-pls-base.txt
But I couldn't find any file matching that name.  Sorry!
--------------------------------------------------------------------------

Could not  actually follow what does that mean,

Any idea?

Sajjad
