NAME

       MPI_Comm_call_errhandler - Passes the supplied error code to the error handler assigned to a communicator

SYNTAX

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

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

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

INPUT PARAMETER

       comm	     communicator with error handler (handle).

       errorcode     error code (integer).

OUTPUT PARAMETERS

       IERROR	     Fortran only: Error status (integer).

DESCRIPTION

       This  function invokes the error handler assigned to the communicator comm with the supplied error code errorcode. If the error handler was
       successfully called, the process is not aborted, and the error handler returns, this function returns MPI_SUCCESS.

NOTES

       Users should note that the default error handler is MPI_ERRORS_ARE_FATAL. Thus, calling this function will abort the processes in  comm	if
       the default error handler has not been changed.

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.

       See the MPI man page for a full list of MPI error codes.

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.
