Abstract
| Distributed synchronization for parallel simulation is generally
classified as being either optimistic or conservative. While
considerable investigations have been conducted to analyze and
optimize each of these synchronization strategies, very little study
on the definition and strictness of causality have been conducted.
Do we really need to preserve causality in all types of simulations?
This paper attempts to answer this question. We argue that significant
performance gains can be made by reconsidering this definition to
decide if the parallel simulation needs to preserve causality. We
investigate the feasibility of unsynchronized parallel simulation
through the use of several queuing model simulations and present a
comparative analysis between unsynchronized and Time Warp simulation.
