# And now you have to ask SimGrid to actually start your actors. # # The easiest way to do so is to implement the behavior of your actor in a single function, # as we do here for the receiver actors. This function can take any kind of parameters, as # long as the last parameters of Actor::create() match what your function expects. Actor.create("receiver", Host.by_name("Fafard"), receiver, "mb42") # If your actor is getting more complex, you probably want to implement it as a class instead, # as we do here for the sender actors. The main behavior goes into operator()() of the class. # # You can then directly start your actor, as follows: Actor.create("sender1", Host.by_name("Tremblay"), Sender()) # If you want to pass parameters to your class, that's very easy: just use your constructors Actor.create("sender2", Host.by_name("Jupiter"), Sender("GloubiBoulga")) # But starting actors directly is considered as a bad experimental habit, since it ties the code # you want to test with the experimental scenario. Starting your actors from an external deployment # file in XML ensures that you can test your code in several scenarios without changing the code itself. # # For that, you first need to register your function or your actor as follows. e.register_actor("sender", Sender) e.register_actor("forwarder", forwarder) # Once actors and functions are registered, just load the deployment file e.load_deployment("actor-create_d.xml") # Once every actors are started in the engine, the simulation can start e.run() # Once the simulation is done, the program is ended
