Hello !

I'm learning MPI and I have a question:

How could I know the rank number of a specific process in a Communicator
?

For example, I start "a.out", "b.out" and "c.out"

In a particular code (let's say "c.out"), how could I know that "a.out"
has a rank
number equal to 0, "b.out" has rank number equal to 1, and so on ... ?

May be an MPI_ALLGATHER ? where each process send its (<rank>,<argv[0])
to
the process # 0 ?

Thanks in advance...

Jep
