| 摘 要： | CFD网格应用平台是ChinaGrid5大应用平台之一，它为各种不同的CFD应用提供了网格基础设施。平台采用了两层架构：上层基于WSRF服务，下层基于并行计算。为了无缝整合各种CFD应用，平台定义了一组包括CFD工作流模板和CFD分类码的重要概念，使用了一系列如CGNS数据可视化工具GVisual的关键技术。目前基于Service Domain的平台原型系统已经开发完成，性能测试表明CFD应用移植其到平台上后性能获得提高。

| Abstract: | The computational fluid dynamics(CFD) grid application platform(GAP) is one of the five major application platforms in ChinaGrid,providing a grid infrastructure for different kinds of CFD applications.The GAP adopts two-level architecture,including service described in Web service resource framework(WSRF) in high level and parallel computing using MPI in low level.Some new concepts are proposed and some key technology are applied in GAP to work with CFD applications seamlessly,such as general CFD work flow template,CFD application classification code and CFD general notation system(CGNS) data visualization tool GVisual.Currently a prototype system based on IBM Service Domain is built and the test result shows that the performance of CFD application migrated on GAP is improved. |
