MPI_Finalize
Terminates MPI execution environment 
Synopsis
#include "mpi.h"
int MPI_Finalize()
Notes
All processes must call this routine before exiting.  The number 
ofprocesses running after this routine is called is undefined;
it is best not to perform much more than a return rc after 
callingMPI_Finalize.
Notes for Fortran
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) 
havean additional argument ierr at the end of the argument list.  
ierris an integer and has the same meaning as the return value of the 
routinein C.  In Fortran, MPI routines are subroutines, and are invoked with 
thecall statement.
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type 
INTEGERin Fortran.
