【Abstract】 With the emergence of high-performance networks and low-cost clusters, it is more possible to employ parallel and distributed simulation widely. First, the characters of various parallel computers are summarized; the concepts of parallel simulations and distributed simulations are identified. Then the strategies of parallel simulations for continuous systems and discrete event systems are generalized. The merits and defects of them are analyzed, the optimizations of them concerning clusters are proposed as well. At last, the various integrated infrastructures of distributed applications are compared in detail, a conclusion is drawn that CORBA is suitable for simulations in small or medium dimension systems.更多还原
