MPI_Abort - Terminates the MPI execution environment


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Abort( comm, errorcode )
            MPI_Comm         comm;
            int              errorcode;

       C++:

            #include <mpi.h>

            void Comm::Abort(
            int               errorcode)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER comm, errorcode, ierror

            CALL MPI_ABORT(comm, errorcode, 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_Abort routine terminates the MPI execution
       environment.  This routine terminates all MPI processes
       associated with the communicator MPI_COMM_WORLD.  MPI
       allows termination of only the processes associated with
       the specified communicator, but this implementation always
       terminates all processes.  This routine accepts the
       following parameters:

       comm           Specifies the communicator of tasks to
                      abort

       errorcode      Specifies the error code to return to the
                      invoking environment

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

       All MPI routines in Fortran (except for MPI_WTIME(3F) and
       MPI_WTICK(3F)) have the additional argument ierror at the
       end of the argument list.  ierror 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 (such as MPI_Datatype(3) and MPI_Comm(3))
       are of type INTEGER in Fortran.
