摘要
时间偏差算法是一种实现并行离散事件模拟的协议,其目的在于利用并行平台并发地执行大规模离散事件的模拟,以缩短仿真时间。为保证结果的正确性,并行模拟必须解决同步问题。时间偏差算法利用虚拟时间来同步各模拟部分之间的执行,通讯接口是利用虚拟时间及回退策略实现同步的部分。对该部分进行了深入的研究,提出了一种优化的实现方案,并对其性能进行了分析。
Time warp is a parallel discrete event synchronization simulation protocol, and its primary goal is to concurrently execute large discrete event simulations in parallel environments in order to reduce the simulation time. Synchronization must be considered to guarantee the correct of simulation result. The protocol uses virtual time to solve this problem, and the communication interface is the part to implement it. This part is deeply discussed, and an optimal implementation is presented.
