int MPI_Scatter(void *sendbuf, int sendcount, MPI_Datatype sendtype,
                void *recvbuf, int recvcount, MPI_Datatype recvtype,
                int root, MPI_Comm comm)

                      recvbuf, recvcount, recvtype,
                      root, comm);
}

{
  int i, j;
  procstats_t *allstats;
