JiST: an efficient approach to simulation using virtual machines†

摘要: Discrete event simulators are important scientific tools and their efficient design execution is the subject of much research. In this paper, we propose a new approach for constructing that leverages virtual machines combines advantages from traditional systems-based language-based simulator designs. We introduce JiST, Java-based simulation system executes discrete simulations both efficiently transparently by embedding semantics directly into Java model. The provides standard benefits modern runtime affords. addition, JiST efficient, out-performing existing highly optimized runtimes. As case study, illustrate practicality framework applying it to construction SWANS, scalable wireless ad hoc network simulator. simulate million node networks, which represents two orders magnitude increase in scale over what can achieve on equivalent hardware at same level detail.
