+\paragraph MSG_ext_mw_master Master code
-This function has to be assigned to a #msg_process_t that will behave as
-the master. It should not be called directly but either given as a
-parameter to #MSG_process_create() or registered as a public function
-through #MSG_function_register() and then automatically assigned to a
-process through #MSG_launch_application().

C style arguments (argc/argv) are interpreted as:
- the number of tasks to distribute
- - the computation size of each task
- - the size of the files associated to each task
- - a list of host that will accept those tasks.

-\paragraph MSG_ext_ms_slave Slave code
+Tasks are evenly sent in a round-robin style.
-This function has to be assigned to a #msg_process_t that has to behave
-as a slave. Just like the master function (described in \ref

+C style arguments (argc/argv) are interpreted as:
