摘要
时间偏差是并行离散事件模拟中广泛使用的一种同步机制。从事件列表管理、消息取消、乐观性控制、状态保存和恢复、内存管理以及全局虚拟时间计算等几个主要方面对时间偏差的并行离散事件模拟进行了探讨,阐述了其存在的问题,并对各种优化策略进行了分析比较和对并行离散事件模拟的应用前景作了一个展望。
Time warp is a synchronization mechanism,which is widely used in Parallel Discrete Event Simulation(PDES).Reviews time warp PDES from several ascepts,i.e.event list management,message cancellation,optimism control,state saving and restoring,memory management,global virtual time computation and so on.Problems of time warp PDES are addressed and various methods for improving simulation performance are analyzed and compared.The prospect of applying PDES to solve real-world problems is lastly given in the paper.
