 \subsubsection faq_MIA_asynchronous I want to do asynchronous communications in MSG
 
-Up until now, there is no asynchronous communications in MSG. However,
-you can create as many process as you want so you should be able to do
-whatever you want... I've written a queue module to help implementing
-some asynchronous communications at low cost (creating thousands of
-process only to handle communications may be problematic in term of
-performance at some point). I'll add it in the distribution asap.
+In the past (version <= 3.4), there was no function to perform asynchronous communications. 
+It could easily be implemented by creating new process when needed though. Since version 3.5, 
+we have introduced the following functions:
+ - MSG_task_isend()
+ - MSG_task_irecv()
+ - MSG_comm_test()
+ - MSG_comm_wait()
+ - MSG_comm_waitall()
+ - MSG_comm_waitany()
+ - MSG_comm_destroy()
+
+We refer you to the description of these functions for more details on their usage as well 
+as to the exemple section on \ref MSG_ex_asynchronous_communications.

-You obviously cannot use pthread_mutexes of pthread_conds. The best
-thing would be to propose similar structures. Unfortunately, we

-MSG_process_suspend() and MSG_process_resume(). You can even do some

+You obviously cannot use pthread_mutexes of pthread_conds since we handle every

+In the past (version <=3.3.4) you could do it by playing with

 MSG_task_put() and MSG_task_Iprobe()).
 
+Since version 3.4, you can use classical synchronization structures. See page \ref XBT_synchro or simply check in
