MPI_Abort(3OpenMPI)													       MPI_Abort(3OpenMPI)

NAME

       MPI_Abort - Terminates MPI execution environment.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Abort(MPI_Comm comm, int errorcode)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_ABORT(COMM, ERRORCODE, IERROR)
	    INTEGER	   COMM, ERRORCODE, IERROR

C++ Syntax
       #include <mpi.h>
       void Comm::Abort(int errorcode)

INPUT PARAMETERS

       comm	 Communicator of tasks to abort.

       errorcode Error code to return to invoking environment.

OUTPUT PARAMETER

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       This  routine  makes a "best attempt" to abort all tasks in the group of comm. This function does not require that the invoking environment
       take any action with the error code. However, a UNIX or POSIX environment should handle this as a return errorcode from the main program or
       an abort (errorcode).

       The Open MPI implementation terminates all processes in all tasks that contain a process in comm, and the error code is not returned to the
       invoking environment.

       Note: All associated processes are sent a SIGTERM.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions  do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except  for
       I/O  function  errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
