18 The S4U interface (SimGrid for you) mixes the full power of SimGrid
19 with the full power of C++. This is the preferred interface to describe
20 abstract algorithms in the domains of Cloud, P2P, HPC, IoT, and similar
23 Since v3.20 (June 2018), S4U is the way to go for long-term
24 projects. It is feature complete, but may still evolve slightly in
25 future releases. It can already be used to do everything that can be
26 done in SimGrid, but you may have to adapt your code in future
27 releases. When this happens, compiling your code will produce
28 deprecation warnings for 4 releases (one year) before the removal of
30 If you want an API that will never ever evolve in the future, you
31 should use the :ref:`deprecated MSG API <MSG_doc>` instead.
36 A typical SimGrid simulation is composed of several |API_s4u_Actors|_, that
37 execute user-provided functions. The actors have to explicitly use the
38 S4U interface to express their :ref:`computation <API_s4u_Exec>`,
39 :ref:`communication <API_s4u_Comm>`, :ref:`disk usage <API_s4u_Io>`,
40 and other |API_s4u_Activities|_, so that they get reflected within the
41 simulator. These activities take place on resources such as |API_s4u_Hosts|_,
42 |API_s4u_Links|_, and |API_s4u_Disks|_. SimGrid predicts the time taken by each
43 activity and orchestrates the actors accordingly, waiting for the
44 completion of these activities.
47 When **communicating**, data is not directly sent to other actors but
48 posted onto a |API_s4u_Mailbox|_ that serves as a rendezvous point between
49 communicating actors. This means that you don't need to know who you
50 are talking to, you just put your communication `Put` request in a
51 mailbox, and it will be matched with a complementary `Get`
52 request. Alternatively, actors can interact through **classical
53 synchronization mechanisms** such as |API_s4u_Barrier|_, |API_s4u_Semaphore|_,
54 |API_s4u_Mutex|_, and |API_s4u_ConditionVariable|_.
56 Each actor is located on a simulated |API_s4u_Host|_. Each host is located
57 in a |API_s4u_NetZone|_, that knows the networking path between one
58 resource to another. Each NetZone is included in another one, forming
59 a tree of NetZones which root zone contains the whole platform. The
60 actors can also be located on a |API_s4U_VirtualMachine|_ that may
61 restrict the activities it contains to a limited amount of cores.
62 Virtual machines can also be migrated between hosts.
64 The :ref:`simgrid::s4u::this_actor <API_s4u_this_actor>` namespace
65 provides many helper functions to simplify the code of actors.

139 See also the :ref:`full API <API_s4u_Activity>` below.
141 =======================
142 Asynchronous Activities
143 =======================
145 Every activity can be either **blocking** or **asynchronous**. For
146 example, :cpp:func:`s4u::Mailbox::put() <simgrid::s4u::Mailbox::put>`
147 and :cpp:func:`s4u::Mailbox::get() <simgrid::s4u::Mailbox::get>`
148 create blocking communications: the actor is blocked until the
149 completion of that communication. Asynchronous communications do not
150 block the actor during their execution but progress on their own.
152 Once your asynchronous activity is started, you can test for its
153 completion using :cpp:func:`s4u::Activity::test() <simgrid::s4u::Activity::test>`.
154 This function returns ``true`` if the activity is completed already.
155 You can also use :cpp:func:`s4u::Activity::wait() <simgrid::s4u::Activity::wait>`
156 to block until the completion of the activity. To wait for at most a given amount of time,
157 use :cpp:func:`s4u::Activity::wait_for() <simgrid::s4u::Activity::wait_for>`.
158 Finally, to wait at most until a specified time limit, use
159 :cpp:func:`s4u::Activity::wait_until() <simgrid::s4u::Activity::wait_until>`.
161 Every kind of activity can be asynchronous.
162 :ref:`s4u::CommPtr <API_s4u_Comm>` are created with :cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>` and
163 :cpp:func:`s4u::Mailbox::get_async() <simgrid::s4u::Mailbox::get_async>`;
164 :ref:`s4u::IoPtr <API_s4u_Io>` are created with :cpp:func:`s4u::Disk::read_async() <simgrid::s4u::Disk::read_async>` and
165 :cpp:func:`s4u::Disk::write_async() <simgrid::s4u::Disk::write_async>`; and
166 :ref:`s4u::ExecPtr <API_s4u_Exec>` are created with
167 :cpp:func:`s4u::Host::exec_async() <simgrid::s4u::Host::exec_async>`.
168 In the future, it will become possible to have asynchronous IPC such as asynchronous mutex lock requests.
170 The following example shows how to have several concurrent
171 communications ongoing. First, you have to declare a vector in which
172 we will store the ongoing communications. It is also useful to have a
175 .. literalinclude:: ../../examples/cpp/comm-waitall/s4u-comm-waitall.cpp
177 :start-after: init-begin
178 :end-before: init-end
181 Then, you start all the communications that should occur concurrently with
182 :cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>`.
183 Finally, the actor waits for the completion of all of them at once
184 with :cpp:func:`s4u::Comm::wait_all() <simgrid::s4u::Comm::wait_all>`.
186 .. literalinclude:: ../../examples/cpp/comm-waitall/s4u-comm-waitall.cpp
188 :start-after: put-begin
192 =====================
193 Activities Life cycle
194 =====================
196 Sometimes, you want to change the setting of an activity before it even starts.
198 .. todo:: write this section
205 Please also refer to the :ref:`API reference for s4u::Mailbox
212 |API_s4u_Mailboxes|_ are rendezvous points for network communications,
213 similar to URLs on which you could post and retrieve data. Actually,
214 the mailboxes are not involved in the communication once it starts,
215 but only to find the contact with which you want to communicate.
217 They are similar to many common things: The phone number, which allows
218 the caller to find the receiver. The Twitter hashtag, which helps
219 senders and receivers to find each other. In TCP, the pair
220 ``{host name, host port}`` to which you can connect to find your peer.
221 In HTTP, URLs through which the clients can connect to the servers.
222 In ZeroMQ, the queues are used to match senders and receivers.
224 One big difference with most of these systems is that no actor is the
225 exclusive owner of a mailbox, neither in sending nor in receiving.
226 Many actors can send into and/or receive from the same mailbox. TCP
227 socket ports for example are shared on the sender side but exclusive
228 on the receiver side (only one process can receive from a given socket
229 at a given point of time).
231 A big difference with TCP sockets or MPI communications is that
232 communications do not start right away after a
233 :cpp:func:`Mailbox::put() <simgrid::s4u::Mailbox::put>`, but wait
234 for the corresponding :cpp:func:`Mailbox::get() <simgrid::s4u::Mailbox::get>`.
235 You can change this by :ref:`declaring a receiving actor <s4u_receiving_actor>`.
237 A big difference with Twitter hashtags is that SimGrid does not
238 offer easy support to broadcast a given message to many
239 receivers. So that would be like a Twitter tag where each message
240 is consumed by the first receiver.
242 A big difference with the ZeroMQ queues is that you cannot filter
243 on the data you want to get from the mailbox. To model such settings
244 in SimGrid, you'd have one mailbox per potential topic, and subscribe
245 to each topic individually with a
246 :cpp:func:`get_async() <simgrid::s4u::Mailbox::get_async>` on each mailbox.
247 Then, use :cpp:func:`Comm::wait_any() <simgrid::s4u::Comm::wait_any>`
248 to get the first message on any of the mailboxes you are subscribed to.
250 The mailboxes are not located on the network, and you can access
251 them without any latency. The network delays are only related to the
252 location of the sender and receiver once the match between them is
253 done on the mailbox. This is just like the phone number that you
254 can use locally, and the geographical distance only comes into play
255 once you start the communication by dialing this number.
257 =====================
258 How to use Mailboxes?
259 =====================
261 You can retrieve any existing mailbox from its name (which is a
262 unique string, just like a Twitter tag). This results in a
263 versatile tool that can be used to build many different
266 To model classical socket communications, use "hostname:port" as
267 mailbox names, and make sure that only one actor reads into a given
268 mailbox. This does not make it easy to build a perfectly realistic
269 model of the TCP sockets, but in most cases, this system is too
270 cumbersome for your simulations anyway. You probably want something
271 simpler, that turns out to be easy to build with the mailboxes.
273 Many SimGrid examples use a sort of yellow page system where the
274 mailbox names are the name of the service (such as "worker",
275 "master", or "reducer"). That way, you don't have to know where your
276 peer is located to contact it. You don't even need its name. Its
277 function is enough for that. This also gives you some sort of load
278 balancing for free if more than one actor pulls from the mailbox:
279 the first actor that can deal with the request will handle it.
281 =========================================
282 How are put() and get() requests matched?
283 =========================================
285 The matching algorithm simple: first come, first serve. When a new
286 send arrives, it matches the oldest enqueued receive. If no receive is
287 currently enqueued, then the incoming send is enqueued. As you can
288 see, the mailbox cannot contain both send and receive requests: all
289 enqueued requests must be of the same sort.
291 .. _s4u_receiving_actor:
293 ===========================
294 Declaring a Receiving Actor
295 ===========================
297 The last twist is that by default in the simulator, the data starts
298 to be exchanged only when both the sender and the receiver are
299 announced (it waits until both :cpp:func:`put() <simgrid::s4u::Mailbox::put()>`
300 and :cpp:func:`get() <simgrid::s4u::Mailbox::get()>` are posted).
301 In TCP, since you establish connections beforehand, the data starts to
302 flow as soon as the sender posts it, even if the receiver did not post
303 its :cpp:func:`put() <simgrid::s4u::Mailbox::put()>` yet.
305 To model this in SimGrid, you can declare a specific receiver to a
306 given mailbox (with the function
307 :cpp:func:`set_receiver() <simgrid::s4u::Mailbox::set_receiver()>`).
308 That way, any :cpp:func:`put() <simgrid::s4u::Mailbox::put()>`
309 posted to that mailbox will start as soon as possible, and the data
310 will already be there on the receiver host when the receiver actor
311 posts its :cpp:func:`get() <simgrid::s4u::Mailbox::get()>`
313 Note that being permanent receivers of a mailbox prevents actors to be
314 garbage-collected. If your simulation creates many short-lived actors
315 that are marked as permanent receiver, you should call
316 ``mailbox->set_receiver(nullptr)`` by the end of the actors so that their
317 memory gets properly reclaimed. This call should be at the end of the
318 actor's function, not in an on_exit callback.
320 ===============================
321 Communicating without Mailboxes
322 ===============================
324 Sometimes you don't want to simulate communications between actors as
325 allowed by mailboxes, but you want to create a direct communication
326 between two arbitrary hosts. This can arise when you write a
327 high-level model of a centralized scheduler, or when you model direct
328 communications such as one-sided communications in MPI or remote
329 memory direct access in PGAS.
331 For that, :cpp:func:`Comm::sendto() <simgrid::s4u::Comm::sendto()>`
332 simulates a direct communication between the two specified hosts. No
333 mailbox is used, and there is no rendezvous between actors. You can
334 freely mix such direct communications and rendezvous-based
335 communications. Alternatively, :cpp:func:`Comm::sendto_init()
336 <simgrid::s4u::Comm::sendto_init()>` and
337 :cpp:func:`Comm::sendto_async() <simgrid::s4u::Comm::sendto_async()>`
338 create asynchronous direct communications.
345 For sake of simplicity, we use `RAII
346 <https://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization>`_
347 for many classes in S4U. This is an idiom where resources are automatically
348 managed through the context. Provided that you never manipulate
349 objects of type Foo directly but always FooPtr references (which are
350 defined as `boost::intrusive_ptr
351 <http://www.boost.org/doc/libs/1_61_0/libs/smart_ptr/intrusive_ptr.html>`_
352 <Foo>), you will never have to explicitly release the resource that
353 you use nor to free the memory of unused objects.
354 Here is a little example:
360 simgrid::s4u::MutexPtr mutex = simgrid::s4u::Mutex::create(); // Too bad we cannot use `new`
362 mutex->lock(); // use the mutex as a simple reference
366 } // The mutex gets automatically freed because the only existing reference gets out of scope
368 Note that Mailboxes, Hosts, and Links are not handled through smart
369 pointers (yet?). This means that it is currently impossible to destroy a
370 mailbox or a link. You can still destroy a host (but probably
371 shouldn't), using :cpp:func:`simgrid::s4u::Host::destroy`.
