基于GMMSTS的协同机制研究

分析了在广域网环境下进行大规模分布仿真时海量异构资源难以协同的问题,提出了一种基于网格的多用户多任务仿真训练系统(GMMSTS).详细研究了GMMSTS中存在的多种协同关系,定义了基于用户和基于联邦的两类协同机制,并讨论了具体实现方案,完成了复杂协作关系的有效管理.GMMSTS已应用到某雷达模拟训练器中,其中的协同管理模块成功地实现了多任务,多用户的协同,取得了良好的效果.

Research on Collaboration Mechanism of GMMSTS

High Level Architecture (HLA) offers standards for enforcing interoperability among simulations as well as re-usability of simulation components. In a large-scale HLA based simulation over WAN, it invokes a lot of federates and various computing resources. In order to improve the performance of Collaboration among federates and resource management, a Grid-based Multi-user and Multi-task Simulation Training System (GMMSTS) was proposed to meet the need of present network simulation training. Then its collaboration mechanism was analyzed in detail and the collaboration management module including grid service client invocation and class encapsulation were discussed. GMMSTS has been designed and realized for a prototype training system for radar equipment. Application results show that the collaboration mechanism in GMMSTS is a promising alternative to existing network simulation training system.
