       comm      Communicator of tasks to abort.

       errorcode Error code to return to invoking environment.

       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.


EERRRROORRSS
       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::ERRORSTHROWEXCEPTIONS, 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
       MPICommseterrhandler; the predefined error handler MPIERRORSRETURN
       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.
