This is an MPI question, not an IPython question.
That said, the answer depends on your MPI implementation. MPI_COMM_WORLD
(which is the communicator you're using here), is populated at process
launch. There are ways to form groups of processes after process launch,
see intracommunicators in the MPI-2 documentation, but you should
understand that this is not a very commonly used technique in the HPC
world.
Cheers,
Aron
