Each actor is located on a simulated |API_s4u_Host|_. Each host is located
itself in a |API_s4u_NetZone|_, that knows the networking path between one
resource to another. Each NetZone is included in another one, forming
-a tree of NetZones which root zone contains the whole platform.

+restrict the activities it contains to a limited amount of cores.
+Virtual machines can also be migrated between hosts.
The :ref:`simgrid::s4u::this_actor <API_s4u_this_actor>` namespace
provides many helper functions to simplify the code of actors.

flow as soon as the sender posts it, even if the receiver did not post
