Saving to a file during parallel computation

            if exitcode == 1
                exit();
            end;

I think it would be cleaner to just do return or something, instead of exit().

there’s no sense in making your parallel workers wait on disk I/O

This doesn’t matter for your specific example if each worker runs for days anyway, assuming I understood that part of your problem correctly?
