* An actor is an independent stream of execution in your distributed application.
*
* You can think of an actor as a process in your distributed application, or as a thread in a multithreaded program.
- * This is the only component in SimGrid that actually does something on its own, executing its own code.
- * A resource will not get used if you don't schedule activities on them. This is the code of Actors that create and schedule these activities.

* An actor is located on a (simulated) host, but it can interact

+ *
* The s4u::Actor API is strongly inspired from the C++11 threads.
- * The <a href="http://en.cppreference.com/w/cpp/thread">documentation

* @section s4u_actor_def Defining the skeleton of an Actor
- *
- * %As in the <a href="http://en.cppreference.com/w/cpp/thread">C++11
+ *
+ * As in the <a href="http://en.cppreference.com/w/cpp/thread">C++11
* standard</a>, you can declare the code of your actor either as a
* pure function or as an object. It is very simple with functions:
- *
+ *
* @code{.cpp}
* #include "s4u/actor.hpp"
- *
+ *
* // Declare the code of your worker
* void worker() {
* printf("Hello s4u");
* simgrid::s4u::this_actor::execute(5*1024*1024); // Get the worker executing a task of 5 MFlops
* };
- *
+ *
* // From your main or from another actor, create your actor on the host Jupiter
- * // The following line actually creates a new actor, even if there is no "new".
+ * // The following line actually creates a new actor, even if there is no "new".
* Actor("Alice", simgrid::s4u::Host::by_name("Jupiter"), worker);
* @endcode
- *
+ *
* But some people prefer to encapsulate their actors in classes and
* objects to save the actor state in a cleanly dedicated location.
* The syntax is slightly more complicated, but not much.
- *
+ *
* @code{.cpp}
* #include "s4u/actor.hpp"
- *
+ *
* // Declare the class representing your actors
* class Worker {
* public:
* simgrid::s4u::this_actor::execute(5*1024*1024); // Get the worker executing a task of 5 MFlops
* }
* };
- *
+ *
* // From your main or from another actor, create your actor. Note the () after Worker
* Actor("Bob", simgrid::s4u::Host::by_name("Jupiter"), Worker());
* @endcode
- *
+ *
* @section s4u_actor_flesh Fleshing your actor
- *
+ *
* The body of your actor can use the functions of the
* simgrid::s4u::this_actor namespace to interact with the world.
* This namespace contains the methods to start new activities
* (executions, communications, etc), and to get informations about
* the currently running thread (its location, etc).
- *
+ *
* Please refer to the @link simgrid::s4u::this_actor full API @endlink.

+ *
* @section s4u_actor_deploy Using a deployment file
- *
+ *
* @warning This is currently not working with S4U. Sorry about that.
- *
+ *
* The best practice is to use an external deployment file as
* follows, because it makes it easier to test your application in
* differing settings. Load this file with
- * s4u::Engine::loadDeployment() before the simulation starts.
+ * s4u::Engine::loadDeployment() before the simulation starts.
* Refer to the @ref deployment section for more information.
