-Since v3.20 (June 2018), S4U is the way to go for long-term
-projects. It is feature complete, but may still evolve slightly in
-future releases. It can already be used to do everything that can be
-done in SimGrid, but you may have to adapt your code in future
-releases. When this happens, compiling your code will produce
-deprecation warnings for 4 releases (one year) before the removal of
-the old symbols.
-If you want an API that will never ever evolve in the future, you
-should use the :ref:`deprecated MSG API <MSG_doc>` instead.

+=====================
+Repeatable Activities
+=====================
+
+In order to simulate the execution of Dataflow applications, we introduced the
+concept of |API_s4u_Tasks|, that can be seen as repeatable activities. A Dataflow
+is defined as a graph of |API_s4u_Tasks|, where each |API_s4u_Tasks| has a set of
+successors and predecessors. When a |API_s4u_Tasks| ends it sends a token to each
+of its successors. Each |API_s4u_Tasks| has to receive a token from each of its
+predecessor to start. Tokens can carry any user-defined data.
+
+|API_s4u_Tasks| are composed of several instances: a dispatcher, a collector, and
+instance_0 to instance_n. The dispatcher rely on a load balancing function to select
+the next instance to fire. Once this instance finishes it fires the collector.
+
+Each instance of an |API_s4u_ExecTask| can be placed on a different host.
+|API_s4u_Comm| activities are automatically created when an instance triggers
+another instance on a different host. Each instance has its own parallelism degree
+to scale horizontally on several cores.
+
+To initiate the execution of a Dataflow, it is possible to some make
+|API_s4u_Tasks| fire one or more activities without waiting for any token with the
+:cpp:func:`s4u::Task::enqueue_firings() <simgrid::s4u::Task::enqueue_firings>`
+function.
+
+The parameters of Tasks can be redefined at runtime by attaching
+callbacks to the
+:cpp:func:`s4u::Task::on_this_start <simgrid::s4u::Task::on_this_start>`
+and
+:cpp:func:`s4u::Task::on_this_completion <simgrid::s4u::Task::on_this_completion>`
+signals. The former is triggered by instances others than the dispatcher and the collector,
+and the latter is triggered by the collector.

mailbox or a link. You can still destroy a host (but probably
shouldn't), using :cpp:func:`simgrid::s4u::Host::destroy`.

+
+ The following errors denote a problem in the SimGrid tool itself. Most of the time, you should let these
+ exception go, so that the simulation stops. But you may want to catch them, for example when you launch
+ SimGrid from a python notebook and want to handle the problem accordingly.
