Terminates MPI execution environment


#include "mpi.h"
int MPI_Finalize()


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.
