Dear Martin,

sorry for the mistake! Of course, I am interested in SimGrid. Thank you veru much for the information.
Kind regards,

Massimo

It's written in Java so you cannot reuse any code from them. Other projects using SimGrid for that are written in C++ (but in other contexts). See http://simgrid.gforge.inria.fr/simgrid/3.17/doc/getting_started.html (page bottom).
