6 /* This example validates the behaviour in presence of node and link fault.
7 * Each test scenario consists in one host/actor (named sender) sending one message to another host/actor.
8 * The space to cover is quite large, since we consider:
9 * * communication types (eager, rendez-vous, one-sided=detached)
10 * * use type (synchronous, asynchronous, init)
11 * * fault type (sender node, link, receiver node)
12 * * any legal permutation of the scenario steps
14 * This program also presents a way to simulate applications that are resilient to links and node faults.
15 * Essentially, it catches exceptions related to communications and it clears the mailboxes when one of the nodes gets
16 * turned off. However, this model would suppose that there would be 2 mailboxes for each pair of nodes, which is
17 * probably unacceptable.
