摘　　要：进行仿真网格原型系统的研究是解决仿真网格关键技术的基础。SGE网格引擎是一个构建本地和集群级网格的工具,通过SGE构建基本的网格平台,根据HLA仿真任务的特点,对分布式仿真网格的原型系统进行了研究和设计。提出了仿真网格的双通道通信机制:一个通道负责仿真网格组件的通信,另一个通道负责HLA仿真任务之间的通信。提出了仿真任务在仿真网格中的三种调度模式:以进程为单位的调度、以联邦成员为单位的调度、以联邦为单位的调度等。通过研究初步实现了仿真网格的原型系统,并对HLA仿真任务的三种调度模式进行了简单的测试。The simulation grid is a distributed simulation platform built through grid technology. On the platform the distributed simulation applications can be executed by utilizing the powerful sharing resource. The research of the simulation grid prototype system is the basis of solving the key technology to build shnulation grid. SGE is a tool to construct the local and duster grids. This paper presents a recent research of building SGE-based distributed simulation grid prototype system. Specifically, its framework provides the dual channels of eommunleation. One channel takes charge of eommtmieating among components of the grid, and the other one takes among HLA federates. In partielular, the grid supports three modes of HLA scheduling tasks, whieh are differentiated aeeording to （1） processes, （2） federates and （3） federations. Results of this study demonstrate the teehnieal feasibility of eonstrueting SGE-based simulation grid, and simply build the prototype system to test the performance of three scheduling task modes.
