void Comm::Abort(int errorcode)
- comm
- Communicator of tasks to abort.
- errorcode
- Error
code to return to invoking environment.
- IERROR
- Fortran
only: Error status (integer).
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.
Almost all MPI routines return an error value;
C routines as the value of the function and Fortran routines in the last
argument. C++ functions 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.
