You might have a look at:

Does anybody know some statistics on MPI usage. e.i. :

Yes, it seems that some advanced "renaming scheme" will fit most of needs.

Reply to myself:
# gdb orterun
(gdb) br MPIR_Breakpoint
(gdb) run
(gdb)
(gdb) detach
(gdb) exit
Am I right?

Actually, the point is deeper than just a debugger naming question.

Surely, I saw th
t together long
before MPI_Init. (BTW: what is this - mpirun that is running as a
background process becomes "stopped" all the time I try to "bg" it?)
What is the "correct" way and how it is supposed to get a debugger
attached to all processes of the program?
