Distributed collaborative high-performance computing framework for sun-earth spatial information

以日地系统活动规律研究为背景,基于美国新近提出的应用于大规模科学计算领域的组件规范CCA(Common Component Architecture),设计提出了日地空间信息分布式协同高性能计算框架DCHF-SI,它集物理模型组件化封装、模拟应用的构建和管理、模型互操作、分布式容错和计算驾驭可视化等服务于一体,能够充分利用网络集成大量的分布式高性能计算资源和空间物理模型资源来构建多物理松耦合模拟应用,支持日地空间信息的分布式协同高性能计算,解决了多物理耦合模拟的复杂性问题,最终为空间天气预报服务系统提供支持。

In the background of study on activity regularity of the Sun-Earth System,this paper proposes a Distributed Collaborative High-performance Computing Framework for Sun-Earth Spatial Information（DCHF-SI）,which is based on the CCA（Common Component Architecture） specifications in the large-scale scientific computing field.It supports component encapsulation for the space physic model,construction and management of simulation application,interoperability of models,distributed fault -tolerant,computing steering and interactive visualization.It is capable of implementing multi-physics loose coupling simulation on internet based on peer component and service oriented pattern,distributed collaborative high-performance computing of spatial information,and ultimately achieves space weather forecasting.
