Error handling

The constants MPI_ERRORS_ARE_FATAL, MPI_ERRORS_RETURN are available as MPI.ERRORS_ARE_FATAL, MPI.ERRORS_RETURN.

If the effective error handler is MPI_ERRORS_RETURN, the wrapper codes will throw appropriate Java exceptions (see section A.7.3).

For now, we omit a specification of Java interface for creating new MPI error handlers, because the detailed interface of the handler function depends on unstandardized features of the MPI implementation.

static void Comm.errorhandlerSet(Errhandler errhandler)

errhandler

new MPI error handler for communicator

Associates a new error handler with communicator at the calling process. Java binding of the MPI operation MPI_ERRORHANDLER_SET.

static Errhandler Comm.errorhandlerGet()

returns:

MPI error handler currently associated with communicator

Returns the error handler currently associated with the communicator. Java binding of the MPI operation MPI_ERRORHANDLER_GET.
