+ * Long proof: actors remain sorted through an arbitrary (implicit, complex but fixed) order in all cases.
*
- * - if there is no kill during the simulation, processes remain sorted according by their PID.
+ * - if there is no kill during the simulation, actors remain sorted according by their PID.
* Rationale: This can be proved inductively.
* Assume that actors_to_run is sorted at a beginning of one round (it is at round 0: the deployment file
* is parsed linearly).
* Let's show that it is still so at the end of this round.
- * - if a process is added when being created, that's from maestro. It can be either at startup
+ * - if an actor is added when being created, that's from maestro. It can be either at startup
* time (and then in PID order), or in response to a process_create simcall. Since simcalls are handled
* in arbitrary order (inductive hypothesis), we are fine.
- * - If a process is added because it's getting killed, its subsequent actions shouldn't matter
- * - If a process gets added to actors_to_run because one of their blocking action constituting the meat
+ * - If an actor is added because it's getting killed, its subsequent actions shouldn't matter
+ * - If an actor gets added to actors_to_run because one of their blocking action constituting the meat
* of a simcall terminates, we're still good. Proof:
- * - You are added from SIMIX_simcall_answer() only. When this function is called depends on the resource
- * kind (network, cpu, disk, whatever), but the same arguments hold. Let's take communications as an
- * example.
+ * - You are added from ActorImpl::simcall_answer() only. When this function is called depends on the
+ * resource kind (network, cpu, disk, whatever), but the same arguments hold. Let's take communications
+ * as an example.
* - For communications, this function is called from SIMIX_comm_finish().
* This function itself don't mess with the order since simcalls are handled in FIFO order.
* The function is called:
* This order is also fixed because it depends of the order in which the surf actions were
* added to the system, and only maestro can add stuff this way, through simcalls.
* We thus use the inductive hypothesis once again to conclude that the order in which synchros are
- * poped out of the set does not depend on the user code's execution order.
+ * popped out of the set does not depend on the user code's execution order.
* - because the communication terminated. In this case, synchros are served in the order given by
* set = model->states.done_action_set;
* while ((synchro = extract(set)))
* SIMIX_simcall_post((smx_synchro_t) synchro->data);
* and the argument is very similar to the previous one.
- * So, in any case, the orders of calls to SIMIX_comm_finish() do not depend on the order in which user
- * processes are executed.
- * So, in any cases, the orders of processes within actors_to_run do not depend on the order in which
- * user processes were executed previously.
+ * So, in any case, the orders of calls to CommImpl::finish() do not depend on the order in which user
+ * actors are executed.
+ * So, in any cases, the orders of actors within actors_to_run do not depend on the order in which
+ * user actors were executed previously.
* So, if there is no killing in the simulation, the simulation reproducibility is not jeopardized.
- * - If there is some process killings, the order is changed by this decision that comes from user-land
+ * - If there is some actor killings, the order is changed by this decision that comes from user-land
* But this decision may not have been motivated by a situation that were different because the simulation is
* not reproducible.
- * So, even the order change induced by the process killing is perfectly reproducible.
+ * So, even the order change induced by the actor killing is perfectly reproducible.
