Abstract

The paper presents the tolerant, hybrid synchronization schema and its benefits for the parallel and distributed simulation of interconnected computer networks. The hybrid schema combines conservative and optimistic synchronization approaches by using lookahead for scheduling special events and using the flexibility of time warp in certain cases. In addition to these classical approaches the introduction of the “tolerance” allows the distributed modules to simulate further ahead than guaranteed by the conservative synchronization schema. This results in significantly smaller simulation runtimes and many other benefits
