ABSTRACT
Load balancing is a crucial factor in achieving good performance for parallel discrete event simulations. In this paper, we present a load-balancing scheme that combines both static partitioning and dynamic load balancing. This static partitioning scheme maps simulation objects to logical processes before simulation starts while the dynamic load-balancing scheme attempts to balance the load during runtime. The static scheme involves two steps. First, the simulation objects that contribute to small lookahead are merged together by using a merging algorithm. Then a partitioning algorithm is applied. The merging is needed to ensure a consistent performance for our dynamic scheme. Our dynamic scheme is tailor-made for an asynchronous simulation protocol that does not rely on null messages. The performance study on a supply-chain simulation shows that the partitioning algorithm and dynamic load balancing are important in achieving good performance.
