Just so we understand better precisely what you'd like to see
illustrated: do you want the process running the notebook to be itself
one of the members of your MPI world (say the rank-0 node)?  Or do you
want the MPI world to start N nodes to which you then attach from a
notebook session and tell them to run various bits of code from within
the notebook?

With a bit of clarity about what you want to do, we should be able to
help you out (and will make that notebook an example in the docs).

Cheers,
