Abstract
Distributed system simulation is enhanced by extending the simulation window. In a described implementation, the simulation window extension is facilitated with a slow message relaxation scheme. For example, especially when the simulation window is extended, slow unscheduled events can arrive at a logical process with a timestamp that is prior to (e.g., less than) the local time of a receiving logical process that is participating in a simulation. To ameliorate issues created by a slow unscheduled message and its corresponding slow unscheduled event, a current logical time of the receiving logical process is substituted for the original timestamp of the slow unscheduled event to transform it into a punctual unscheduled event.
