Hi [~sseth]
Back to your first suggestion. The YTDC is a class without constructor and only
has main method. To use it without creating new JVM, I have to modify its code.
My plan is to modify the LCL and let it control the parallelism of running
tasks from same vertex. The YTDC will extend Thread and have a run method as
stub for LCL to use it directly. I don't want to waste time from both side. Do
you have any suggestion for this plan? Thank you in advance.
