"Parallel execution of Ptolemy models on multicore machines - Enable parallel execution of Ptolemy models on multicore machines. Provide a way for modelers to partition models for parallel execution."

There are several approaches to this.

• Use ThreadedComposite:

E.A. Lee, "ThreadedComposite: A Mechanism for Building Concurrent and Parallel Ptolemy II Models," EECS Department, University of California, Berkeley, Technical Report No. UCB/EECS-2008-151, December 7, 2008.

• Use PN, where each actor is a thread.

• Use Modular Code Generation

The problem we face now is that Publishers and Subscribers have problem crossing Opaque boundaries.
