For + * example, a P2P protocol reacts to requests from the user, but + * does nothing if there is no such event. + * + * In such situations, SimGrid allows to write your protocol in your + * C file, and the events to react to in a separate text file. + * Declare a function handling each of the events that you want to + * accept in your trace files, register them using \ref + * xbt_replay_action_register in your main, and then use \ref + * MSG_action_trace_run to launch the simulation. You can either + * have one trace file containing all your events, or a file per + * simulated process. Check the tesh files in the example directory + * for details on how to do it. + * + * This example uses this approach to replay MPI-like traces. It + * comes with a set of event handlers reproducing MPI events. This + * is somehow similar to SMPI, yet differently implemented.
