【摘要】 根据天文数据的广域分布、异构性以及共享性的特点,将网格技术应用于虚拟天文台项目中,并与工作流技术相结合,提出了集成网格技术的虚拟天文台的工作流体系结构。该结构利用网格技术有效解决了虚拟天文台建设中天文数据资源、计算资源、存储资源等各种资源的全面共享,工作流技术集成网格技术则使得服务调用应用的流程更加规范,实现了协同合作,达到更高的效率,以期望达到真正的无缝连接。更多还原

【Abstract】 Grid technique and workflow technique are applied to Virtual Observatory because of the trait of the numerous distributed,heterogeneous and shared data of Virtual Observatory. This paper proposes a workflow model of China Virtual Observatory for astronomy application based on science data grid,which solves the whole shareness of observatory data resources ,computing resources and storing resources. The integration of grid technique and workflow technique makes it possible to collaborate, aiming to make a criterion of working process of Virtual Observatory and improve processing efficiency.更多还原
