MPI_Finalize(3)

NAME
     MPI_Finalize - Terminates the MPI execution environment

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Finalize()


     C++:

          #include <mpi.h>

          void Finalize()


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER ierror

          CALL MPI_FINALIZE(ierror)


STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Finalize routine terminates the MPI execution environment.  All
     processes must call this routine before exiting.  The number of processes
     running after this routine is called is undefined.

     ierror      Specifies the return code value for successful completion,
                 which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the
                 mpif.h file.

NOTES
     MPI Processes which have been started using either MPI_Comm_spawn or
     MPI_Comm_spawn_multiple will not return from the MPI_Finalize call until
     the parent MPI processes have also invoked MPI_Finalize.
