I tested and the number of ranks in world comm is correct. I couldn't find
the bug that causes the program to produce erroneous answers when this
scheme is used, though.

Thank you, that's good to know.
Yes, testing this now. I'll let you know

FWIW: I just tested it on master, and all the procs are in the same comm_world.
However, that was with a C application, not Java.
Saliya: can you please check to see if Java is behaving differently? A simple
app that gets and prints out its rank is all that is required.

Thanks, Udayanga. I'll check this.
Ralph, I'll try to print some debug info from the code and check why this
logic fails and will let you know.

Actually, what Saliya describes sounds like a bug - those procs must all be
assigned to the same comm_world.
Saliya: are you sure they are not? What ranks are you seeing?

Hi,
I think orte/ompi-mca foward number of environment variables (ie:- $OMPI_*)
to its ranks. So I believe you may use $OMPI_COMM_WORLD_LOCAL_RANK to
specifically filter out parameters within the script.

Hi,
I am invoking my Java MPI program as,
mpirun opts script.sh
Now, I want to pass some rank specific argument to this script. For
example, I need to enable GC logs for one of the processes only, so I need
to pass an argument to the JVM if that's rank0 to do GC logs.
I've asked the same questi
