Research and Implementation of Parallel Simulation Engine for Component Based-on BOM

在组件化建模与仿真领域内,基于BOM规范的组件建模与仿真环境KD-SmartSim得到了广泛应用,它通过RTI实现了组件仿真系统的并行运算,但是其运行性能较低。讨论了KD-SmartSim系统存在的不足,在继承其基于BOM规范组件建模的基础上,提出了新的支持组件并行化计算的结构,设计了SPMD运行模式的并行组件仿真引擎,研究和开发了各种模型计算需要的仿真服务,实现了支持串行和保守时间推进机制的组件并行仿真引擎原型系统。测试结果表明该系统具备BOM组件仿真运行必须的功能,能够显著地提升组件系统的运行性能。

In the field of M＆S of Component, the component modeling and simulation environment KD-SmartSim based-on BOM specification has been used widely. The application composed of components in KD-SmartSim employs RTI to achieve parallelism, but its performance is inefficient. In this study, the deficiencies of KD-SmartSim were discussed, and a new parallelization structure for component which inherits the concept of BOM component modeling was presented. A parallel simulation engine for components in the form of SPMD was designed, which implements various services required by model computing. In the prototype system, the sequence and conservative time advancing were completed now. The experiment shows that the engine has all capacities which can support BOM component executing and can improve the performance of simulation system composed of components greatly.
