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

150 See also the :ref:`full API <API_s4u_Activity>` below.
152 =======================
153 Asynchronous Activities
154 =======================
156 Every activity can be either **blocking** or **asynchronous**. For
157 example, :cpp:func:`s4u::Mailbox::put() <simgrid::s4u::Mailbox::put>`
158 and :cpp:func:`s4u::Mailbox::get() <simgrid::s4u::Mailbox::get>`
159 create blocking communications: the actor is blocked until the
160 completion of that communication. Asynchronous communications do not
161 block the actor during their execution but progress on their own.
163 Once your asynchronous activity is started, you can test for its
164 completion using :cpp:func:`s4u::Activity::test() <simgrid::s4u::Activity::test>`.
165 This function returns ``true`` if the activity is completed already.
166 You can also use :cpp:func:`s4u::Activity::wait() <simgrid::s4u::Activity::wait>`
167 to block until the completion of the activity. To wait for at most a given amount of time,
168 use :cpp:func:`s4u::Activity::wait_for() <simgrid::s4u::Activity::wait_for>`.
169 Finally, to wait at most until a specified time limit, use
170 :cpp:func:`s4u::Activity::wait_until() <simgrid::s4u::Activity::wait_until>`.
172 Every kind of activity can be asynchronous:
174 - :ref:`s4u::CommPtr <API_s4u_Comm>` are created with
175 :cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>` and
176 :cpp:func:`s4u::Mailbox::get_async() <simgrid::s4u::Mailbox::get_async>`.
177 - :ref:`s4u::IoPtr <API_s4u_Io>` are created with
178 :cpp:func:`s4u::Disk::read_async() <simgrid::s4u::Disk::read_async>` and
179 :cpp:func:`s4u::Disk::write_async() <simgrid::s4u::Disk::write_async>`.
180 - :ref:`s4u::ExecPtr <API_s4u_Exec>` are created with
181 :cpp:func:`s4u::Host::exec_async() <simgrid::s4u::Host::exec_async>`.
182 - In the future, it will become possible to have asynchronous IPC
183 such as asynchronous mutex lock requests.
185 The following example shows how to have several concurrent
186 communications ongoing. First, you have to declare a vector in which
187 we will store the ongoing communications. It is also useful to have a
190 .. literalinclude:: ../../examples/cpp/comm-waitall/s4u-comm-waitall.cpp
192 :start-after: init-begin
193 :end-before: init-end
196 Then, you start all the communications that should occur concurrently with
197 :cpp:func:`s4u::Mailbox::put_async() <simgrid::s4u::Mailbox::put_async>`.
198 Finally, the actor waits for the completion of all of them at once
200 :cpp:func:`s4u::Comm::wait_all() <simgrid::s4u::Comm::wait_all>`.
202 .. literalinclude:: ../../examples/cpp/comm-waitall/s4u-comm-waitall.cpp
204 :start-after: put-begin
209 =====================
210 Activities Life cycle
211 =====================
213 Sometimes, you want to change the setting of an activity before it even starts.
215 .. todo:: write this section
222 Please also refer to the :ref:`API reference for s4u::Mailbox
229 |API_s4u_Mailboxes|_ are rendezvous points for network communications,
230 similar to URLs on which you could post and retrieve data. Actually,
231 the mailboxes are not involved in the communication once it starts,
232 but only to find the contact with which you want to communicate.
234 They are similar to many common things: The phone number, which allows
235 the caller to find the receiver. The Twitter hashtag, which helps
236 senders and receivers to find each other. In TCP, the pair
237 ``{host name, host port}`` to which you can connect to find your peer.
238 In HTTP, URLs through which the clients can connect to the servers.
239 In ZeroMQ, the queues are used to match senders and receivers.
241 One big difference with most of these systems is that no actor is the
242 exclusive owner of a mailbox, neither in sending nor in receiving.
243 Many actors can send into and/or receive from the same mailbox. TCP
244 socket ports for example are shared on the sender side but exclusive
245 on the receiver side (only one process can receive from a given socket
246 at a given point of time).
248 A big difference with TCP sockets or MPI communications is that
249 communications do not start right away after a
250 :cpp:func:`Mailbox::put() <simgrid::s4u::Mailbox::put>`, but wait
251 for the corresponding :cpp:func:`Mailbox::get() <simgrid::s4u::Mailbox::get>`.
252 You can change this by :ref:`declaring a receiving actor <s4u_receiving_actor>`.
254 A big difference with Twitter hashtags is that SimGrid does not
255 offer easy support to broadcast a given message to many
256 receivers. So that would be like a Twitter tag where each message
257 is consumed by the first receiver.
259 A big difference with the ZeroMQ queues is that you cannot filter
260 on the data you want to get from the mailbox. To model such settings
261 in SimGrid, you'd have one mailbox per potential topic, and subscribe
262 to each topic individually with a
263 :cpp:func:`get_async() <simgrid::s4u::Mailbox::get_async>` on each mailbox.
264 Then, use :cpp:func:`Comm::wait_any() <simgrid::s4u::Comm::wait_any>`
265 to get the first message on any of the mailboxes you are subscribed to.
267 The mailboxes are not located on the network, and you can access
268 them without any latency. The network delays are only related to the
269 location of the sender and receiver once the match between them is
270 done on the mailbox. This is just like the phone number that you
271 can use locally, and the geographical distance only comes into play
272 once you start the communication by dialing this number.
274 =====================
275 How to use Mailboxes?
276 =====================
278 You can retrieve any existing mailbox from its name (which is a
279 unique string, just like a Twitter tag). This results in a
280 versatile tool that can be used to build many different
283 To model classical socket communications, use "hostname:port" as
284 mailbox names, and make sure that only one actor reads into a given
285 mailbox. This does not make it easy to build a perfectly realistic
286 model of the TCP sockets, but in most cases, this system is too
287 cumbersome for your simulations anyway. You probably want something
288 simpler, that turns out to be easy to build with the mailboxes.
290 Many SimGrid examples use a sort of yellow page system where the
291 mailbox names are the name of the service (such as "worker",
292 "master", or "reducer"). That way, you don't have to know where your
293 peer is located to contact it. You don't even need its name. Its
294 function is enough for that. This also gives you some sort of load
295 balancing for free if more than one actor pulls from the mailbox:
296 the first actor that can deal with the request will handle it.
298 =========================================
299 How are put() and get() requests matched?
300 =========================================
302 The matching algorithm simple: first come, first serve. When a new
303 send arrives, it matches the oldest enqueued receive. If no receive is
304 currently enqueued, then the incoming send is enqueued. As you can
305 see, the mailbox cannot contain both send and receive requests: all
306 enqueued requests must be of the same sort.
308 .. _s4u_receiving_actor:
310 ===========================
311 Declaring a Receiving Actor
312 ===========================
314 The last twist is that by default in the simulator, the data starts
315 to be exchanged only when both the sender and the receiver are
316 announced (it waits until both :cpp:func:`put() <simgrid::s4u::Mailbox::put()>`
317 and :cpp:func:`get() <simgrid::s4u::Mailbox::get()>` are posted).
318 In TCP, since you establish connections beforehand, the data starts to
319 flow as soon as the sender posts it, even if the receiver did not post
320 its :cpp:func:`put() <simgrid::s4u::Mailbox::put()>` yet.
322 To model this in SimGrid, you can declare a specific receiver to a
323 given mailbox (with the function
324 :cpp:func:`set_receiver() <simgrid::s4u::Mailbox::set_receiver()>`).
325 That way, any :cpp:func:`put() <simgrid::s4u::Mailbox::put()>`
326 posted to that mailbox will start as soon as possible, and the data
327 will already be there on the receiver host when the receiver actor
328 posts its :cpp:func:`get() <simgrid::s4u::Mailbox::get()>`
330 Note that being permanent receivers of a mailbox prevents actors to be
331 garbage-collected. If your simulation creates many short-lived actors
332 that are marked as permanent receiver, you should call
333 ``mailbox->set_receiver(nullptr)`` by the end of the actors so that their
334 memory gets properly reclaimed. This call should be at the end of the
335 actor's function, not in an on_exit callback.
337 ===============================
338 Communicating without Mailboxes
339 ===============================
341 Sometimes you don't want to simulate communications between actors as
342 allowed by mailboxes, but you want to create a direct communication
343 between two arbitrary hosts. This can arise when you write a
344 high-level model of a centralized scheduler, or when you model direct
345 communications such as one-sided communications in MPI or remote
346 memory direct access in PGAS.
348 For that, :cpp:func:`Comm::sendto() <simgrid::s4u::Comm::sendto()>`
349 simulates a direct communication between the two specified hosts. No
350 mailbox is used, and there is no rendezvous between actors. You can
351 freely mix such direct communications and rendezvous-based
352 communications. Alternatively, :cpp:func:`Comm::sendto_init()
353 <simgrid::s4u::Comm::sendto_init()>` and
354 :cpp:func:`Comm::sendto_async() <simgrid::s4u::Comm::sendto_async()>`
355 create asynchronous direct communications.
362 For sake of simplicity, we use `RAII
363 <https://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization>`_
364 for many classes in S4U. This is an idiom where resources are automatically
365 managed through the context. Provided that you never manipulate
366 objects of type Foo directly but always FooPtr references (which are
367 defined as `boost::intrusive_ptr
368 <http://www.boost.org/doc/libs/1_61_0/libs/smart_ptr/intrusive_ptr.html>`_
369 <Foo>), you will never have to explicitly release the resource that
370 you use nor to free the memory of unused objects.
371 Here is a little example:
377 simgrid::s4u::MutexPtr mutex = simgrid::s4u::Mutex::create(); // Too bad we cannot use `new`
379 mutex->lock(); // use the mutex as a simple reference
383 } // The mutex gets automatically freed because the only existing reference gets out of scope
385 Note that Mailboxes, Hosts, and Links are not handled through smart
386 pointers (yet?). This means that it is currently impossible to destroy a
387 mailbox or a link. You can still destroy a host (but probably
388 shouldn't), using :cpp:func:`simgrid::s4u::Host::destroy`.
