Is it not possible to reproduce locally? Most clusters have a way to submit
an interactive job (which would let you start this thing and then inspect
individual processes). Ashley's Padb suggestion will certainly be better in
a non-interactive environment.

Is control returning to your script after rank 0 has exited? In that case,
you can just put this on the next line.

"ps" from the command line, or getpid() from C code.
