# 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.

# 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:
- simgrid.Actor.create("sender1", simgrid.Host.by_name("Tremblay"), Sender())
+ 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
- simgrid.Actor.create("sender2", simgrid.Host.by_name("Jupiter"), Sender("GloubiBoulga"));
+ 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
# 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/actor-create_d.xml")
+ # 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
+ # Once the simulation is done, the program is ended
