Abstract

In this paper we present an empirical comparison among conservative synchronization protocols for distributed discrete-event simulation which are suitable for the bulk-synchronous parallel (BSP) model of computing. A number of optimizations were introduced which produced improved protocols. We also establish comparisons with an optimistic synchronization protocol called BSP Time Warp. We assessed the performance of the protocols by using architecture independent performance metrics, and quantified empirically these metrics by executing a demanding work-load under different situations.
