Thanks Yang I am doing the same to understand the flow, but I have very basic/naive/foolish question that, when we assign a task for multiprocessor simulation, how simulator understand/keep_info that it is shared & can you please tell some simple multiprocessor program/example that can be simulated for understanding.
