| 摘 要： | 在基于消息传递的分布式系统上，根据两类异步并行计算的特点，结合连续系统仿真对并行计算的要求，分析了异步并行计算对仿真结果的影响，提出了用异步并行计算方法进行连续系统仿真并保证不出现计算过程“混乱”的限制条件，实践证明，满足文中限制条件的异步并行仿真计算比相应的同步并行仿真计算具有更高的加速性能。

| Abstract: | In this paper, it is analyzed that the effect of asynchronous parallel computation on parallel simulation on a multicomputer system. A limit condition is proposed to guarantee that no chaotic operation appears in totally asynchronous parallel simulation of continuous system so as to ensure the simulation results correct. As partially asynchronous parallel simulation as concerned, the limit to asynchronous measure is also presented in the paper. Experiment results show that under the limit condition the asynchronous parallel simulation could gain much higher speedup than its synchronous counterpart. |
