- It's hard to think of a simpler example: it is just sending one message back and forth.
- The tesh file laying in the directory show how to start the simulator binary, highlighting how to pass options to
- the simulators (as detailed in Section \ref options).

Another good old example, where one Master process has a bunch of task to dispatch to a set of several Worker
processes.

@section s4u_ex_actors Acting on Actors
@ref examples/s4u/actor-create/s4u-actor-create.cpp \n
Most actors are started from the deployment XML file, but they exist other methods.
+ - <b>Actors using CPU time</b>.
+ @ref examples/s4u/actor-execute/s4u-actor-execute.cpp \n
+ The computations done in your program are not reported to the
+ simulated world, unless you explicitely request the simulator to pause
+ the actor until a given amount of flops gets computed on its simulated
+ host.

- <b>Daemonize actors</b>
@ref examples/s4u/actor-daemon/s4u-actor-daemon.cpp \n
Some actors may be intended to simulate daemons that run in background. This example show how to transform a regular
Actors can be suspended and resumed during their executions
thanks to the @ref suspend and @ref resume methods.
+ - <b>Priority actors</b>.
+ @ref examples/s4u/actor-priority/s4u-actor-priority.cpp \n
+ Actors can be launched according their priorities thanks to the @ref

- <b>Kill actors</b>.
@ref examples/s4u/actor-kill/s4u-actor-kill.cpp \n
Actors can forcefully stop other actors with the @ref kill method.

+ @ref examples/s4u/actor-lifetime/s4u-actor-lifetime.cpp

@ref examples/s4u/actor-migration/s4u-actor-migration.cpp \n
Actors can move or be moved from a host to another with the @ref migrate method.
