摘　　要：随机仿真是描述反应-扩散系统随机特征的一种重要研究方法,但这种仿真的计算量很大,非常耗时,需要并行离散事件仿真PDES技术的支持。针对反应-扩散系统的特点,基于JAMES II离散事件仿真实验框架,设计实现了基于逻辑进程LP范型的并行分布式反应-扩散系统随机仿真平台。主要设计实现了LP范型模型接口、PDES仿真器以及分布式通信方法。利用该平台建立了经典反应-扩散Lotka-Volterra系统LP范型仿真模型,实验结果复现了Lotka-Volterra系统的震荡特性,验证了平台的有效性。Stochastic simulation is a very important approach to describe the stochastic characteristics of reaction-diffusion systems.But stochastic simulations are often highly compute-intensive and time-consuming,which introduces greater demands for the support of efficient parallel discrete event simulation（PDES）.According to the characteristics of reaction-diffusion systems,based on JAMES II discrete event simulation framework,a parallel and distributed stochastic simulation platform for reaction-diffusion systems of LP paradigm was proposed,which included the design and implementation of the interfaces of LP paradigm,a PDES simulator and a novel distributed communication approach.Based on the modeling interfaces of this framework,a LP-based simulation model of the classical reaction-diffusion Lotka-Volterra system was built,and experiment results represent the fluctuation of the Lotka-Volterra system,which testifies the validity of this platform.
