[MPICH2-dev] possible bug in mpich2

[Rajeev Thakur]

Well, you are not using much of MPI in this code other than init, finalize,
comm_rank, comm_size. If you comment out everything else in the code other
than these MPI functions, and the code runs, you can eliminate the
possibility that the problem may be in MPI.
