 \li GRAS (<em>not functionnal yet</em>) is an ongoing project to emulate virtual virtual platforms
     through SURF. As a consequence a code developped using the GRAS
     framework is able to run as well in the real-world as in the

 \li SMPI (<em>not functionnal yet</em>) is an ongoing project to enable MPI code to run on top of a
     virtual platform through SURF. It follows the same principle as
     the ones used in GRAS but is specific to MPI applications.
 
+Here is a figure the depicts the relation between those different modules.
