\li Slave Code

Here, we see the use of simgrid.Task.recv(alias) to receive a task with a specific alias,
this function return directly the task recevied.

so you can exchange any kind of data (tables, matrix, strings,…) between process via tasks.
\li Sender process
-\verbatim
+\verbatim
task = simgrid.Task.new("data_task",task_comp,task_comm);
task['matrix'] = my_matrix;
task['table'] = my_table;
\endverbatim
Note that in lua, both sender and receiver share the same lua task.
So that the receiver could joint data directly on the received task without sending it back.
- You can find a complet example (matrix multiplication case) in the file example/lua/mult_matrix.lua.

\subsection bindings_binding_lua_example_bypass Bypass XML
and describe your platform directly from the code, with lua bindings it's Possible !! how ?
We provide some additional (tricky?) functions in lua that allows you to set up your own platform without using the XML files
( this can be useful for large platforms, so a simple for loop will avoid you to deal with an annoying XML File ;) )

\li set Routing mode

for each host you have to specify which route to choose to access to the rest of hosts connected in the grid.

simgrid.Host.setFunction("Fafard","Slave",1,{"2"});
