基于SGE的分布式仿真网格框架研究

SGE(SunGridEngine)是构建本地和集群级网格的工具。研究以SGE为基础,根据HLA仿真任务的特点,进行分布式仿真网格的框架研究和设计。分析了仿真网格的时间管理机制和仿真任务的迁移机制,采用点检查的方式实现了仿真任务迁移和动态调度,提供了用户级和内核级的点检查任务的支持。提出了仿真网格的双通道通信机制和仿真任务在仿真网格中的两种调度模式。通过研究构建了仿真网格的原型系统,并进行了HLA仿真应用的测试。

Research of SGE-based Distributed Simulation Grid Framework

Sun Grid Engine(SGE)can be used to construct local and cluster grids.A recent research of building SGE-based distributed simulation grid framework was proposed,where simulation grid could execute HLA-based applications which were submitted to the grid by simulation users.Time management of simulation grid and task migration mechanism of simulation application were discussed.Further,checkpoint approach was adopted to implement the migration and dynamic scheduling of simulation task.The simulation grid framework supports the user-level and kernel-level checkpoint of simulation task.Specifically,the framework provides the dual channels of communication.Besides,the grid supports two modes of HLA scheduling tasks,which are differentiated according to processes and federates.Results of this study demonstrate the technical feasibility of constructing SGE-based simulation grid,and build a prototype system to execute HLA simulation tasks.
