Research for Time Management of Simultaneous Event and Distributed Simulation

对基于GVT算法的全局控制机制中的瞬间消息及并发报告两大难点的核心问题进行深入的研究和讨论。文章首先介绍了GVT的定义,紧接着讨论了它与LBTS的区别,其次分析了瞬间消息问题及其解决途径,在此基础上提出了一种简单的同步GVT算法。文章余下部分深入讨论了并发报告问题,并提供了解决该问题的基本异步GVT算法,最后在深入阐述一致切点、双切点机制的基础上提出了双切点GVT算法,并详尽描述了这个优化GVT算法的设计与实现。

The research on the transient message problem and simultaneous reporting problem was discussed, which are the most difficult core issue in the global control mechanism based on the Global Virtual Time （GVT） algorithm. The definition of the GVT and the difference from LBTS were introduced, and then the transient message problem was analyzed and a simple synchronous GVT algorithm was provided. The simultaneous reporting problem was further discussed and the basic asynchronous GVT algorithm was offered. The consistent cut and two-cuts mechanism were described, and on this condition, the two-cuts GVT algorithm was put forward., How to design and achieve this improved GVT algorithm was described in detail.
