This Note describes a persistent simulation environment (PSE) for persistence, object-oriented simulation, and prefetching of objects. Object prefetching optimizes the swapping of persistent objects to and from main memory. It is a type of smart virtual memory system that retrieves objects required by the application program. The authors discuss prefetching for two different algorithms: Dijkstra's shortest path algorithm and the traveling salesman. Finally, they analyze the use of prefetching by presenting empirical and theoretical results for performance improvements.
