摘要
仿真网格是利用网格技术构建的分布式仿真应用平台,仿真网格通信机制是仿真任务能够使用强大而分散仿真共享资源的前提,是构建仿真网格平台的关键。在基于网格引擎(Sun G rid Engine,SGE)框架构建的分布式仿真网格中,根据仿真网格执行分布交互式仿真任务的特点,采用了将网格中的组件与通信层分开的通信方式,使得通信作为一个独立的部分存在。在此基础上提出并实现了仿真网格的双通道通信机制:一个通道负责网格组件之间的通信,通过通信进程(comm-proc)和消息机制(m essage)以及通信库(S imG-comm lib)实现网格组件之间数据交互;另一个通道负责仿真网格中基于高层体系结构(HLA)的仿真联邦成员之间的通信,通过S imG-rtid守护进程和RTI管理器实现仿真网格中提交联邦之间的数据交换和同步。
The simulation grid is a distributed simulation platform built by grid technology. Its communication mechanism is the key technology for building simulation grid platform, and the prerequisite that makes those submitted simulation tasks utilize the distributed and powerful sharing resources. In the distributed simulation grid with a Sun Grid Engine （SGE） - based framework, based on the characteristics of distributed interactive simulation tasks running in the simulation grid, we adopted a method that separates the grid components and the communication layer, thus making the communication as a separate part. Further, this paper proposes communication mechanism of dual channels. One channel takes charge of communications among components of grid. The interaction among grid components can be achieved through commprocs, message, SimG - commlib and so on. The other channel is responsible for communications among HLA federates. It includes SimG - rtid daemon and RTI manager which ensure the simulation data exchange and synchronization among federates submitted by users.
