Zusammenfassung:This paper describes a time warp mechanism designed to exploit temporal uncertainty (TU) in distributed simulation. Novel in the proposed approach are: a formal event model where events are assigned time intervals instead of usual punctual timestamps; an aggressive cancellation technique which shifts overheads from communications to computation; and an implementation in Java which deploys a framework for distributed simulations over the Internet. The paper introduces the time warp mechanism and reports some experimental results using a large PCS model. The experiments confirm that TU is able to speedup simulation without compromising the accuracy of the results.
