Your code runs just fine using latest MPICH 3.1 in my Mac laptop when
using 2 processes. My guess is that you executed your program with
just one process instead of two. Please add a check to make sure your
are using nprocs >= 2 (i.e, that the size of MPI_COMM_WORLD is at
least two).

PS: As Jeff said, this ML is not appropriate for general user questions.
