Hi.

One doubt arise on my mind.

If I do an MPIRUN of, say, 4 process, I got an MPI_COMM_WORLD of 4
elements... can I _add_ some more processes doing another MPIRUN and
creating some inter-communicator between the firse MPI_COMM_WORL and the
"second" MPI_COMM_WORLD ?

Can I define a group that consist of ALL the processes I run on
subsequent MPIRUN ?
