1) Do I remember correctly that Ptolemy does not in any way support Java concurrency or multi-threading? If so, then I would assume that one couldn't safely run 2 models in one JVM, even if each had its own instances of TypedCompositeActor, Manager, Director, etc. If one wanted concurrency, one would run separate JVM's, each with one model that would have no contact with any other model. Right?
2) If (in one JVM) I had a program running that wanted to run several models (similar to each other), one after the other, how much reuse of Ptolemy instances makes sense? Would you recommend nulling all references after each model run, and instantiating all Ptolemy objects fresh? Or would it make any sense to reuse the same TypedCompositeActor, Manager, Director, etc? Regardless of which approach I use, I plan to delete all actors from the first model run and create all actors for the second run fresh, for reasons involving the nature of my simulation. Does Ptolemy have a way to scrub all actors out of a model, allowing the creation of new ones? I look forward to your clarifications.
