# 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.

# 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"))
