基于仿真网格的空地作战系统设计研究

网格是新一代信息基础技术,其目的是实现资源共享。根据现有的基于HLA构建的分布式仿真系统存在的缺陷,利用网格技术的优势研究并提出了基于负载动态信息的作业迁移策略,将过载节点上的进程迁移到合适的其它节点上运行。以空地作战对抗系统为例,通过构建分布式仿真系统负载平衡模块实现了分布式动态调度,并阐述系统总体设计的实现方法。实验表明所提方案有效可行,系统动态性能得到明显改善,为提高分布仿真中资源利用效率和扩大仿真规模提供了一种可行的方案。

Scheduling Method of Resource for Simulation Grid System

The grid is a new kind of information infrastructure for resource sharing. Considering the drawbacks of existing distributed simulation system and using the grid technology,based on dynamic load information,a job schedule mechanism was put forward by migrating the running process to certain suitable computation node .The load balance module was built,which took the multi-weapon simulation system as an example to illustrate the development and the realization of the distributed dynamic scheduling. And the design of this system was proposed. Simulation results verify that the method is feasible,improvement of the dynamic property is prominent,and obviously the method could make contribution to constructing the large-scale military simulation applications and enhance the utilization of resource in simulation.
