MPI_Finalize(3)			      MPI		       MPI_Finalize(3)

NAME
       MPI_Finalize -  Terminates MPI execution environment

SYNOPSIS
       int MPI_Finalize( void )

NOTES
       All  processes  must  call  this routine before exiting.	 The number of
       processes running after this routine is called is undefined; it is best
       not to perform much more than a return rc after calling MPI_Finalize .

THREAD AND SIGNAL SAFETY
       The  MPI standard requires that MPI_Finalize be called only by the same
       thread that initialized MPI with either MPI_Init or MPI_Init_thread .

NOTES FOR FORTRAN
       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK )  have
       an  additional  argument ierr at the end of the argument list.  ierr is
       an integer and has the same meaning as the return value of the  routine
       in  C.	In Fortran, MPI routines are subroutines, and are invoked with
       the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in
       Fortran.

ERRORS
       All  MPI	 routines  (except  MPI_Wtime  and MPI_Wtick ) return an error
       value; C routines as the value of the function and Fortran routines  in
       the last argument.  Before the value is returned, the current MPI error
       handler is called.  By default, this error handler aborts the MPI  job.
       The error handler may be changed with MPI_Comm_set_errhandler (for com‐
       municators),	MPI_File_set_errhandler	    (for      files),	   and
       MPI_Win_set_errhandler	(for   RMA   windows).	  The	MPI-1  routine
       MPI_Errhandler_set may be used but its use is deprecated.   The	prede‐
       fined error handler MPI_ERRORS_RETURN may be used to cause error values
       to be returned.	Note that MPI does not guarentee that an  MPI  program
       can  continue  past an error; however, MPI implementations will attempt
       to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
