国家高性能计算环境的虚拟数据空间运行支撑技术研究

Study of technique support on the operation of virtual data space in national high performance computing environment

国家高性能计算环境的特点是广域分散、系统异构、存储资源隔离自治,这对存储设备管理、数据跨域共享等提出了极大的挑战。首先阐述了虚拟数据空间系统的概念,然后分析了其作为国家高性能计算环境的一部分,如何通过视图访问、数据共享、计算环境对接有效降低跨域的访问开销;接着通过模块化方式将虚拟数据空间系统与国家高性能计算环境进行深度的融合,将其功能补充到国家高性能计算环境中;最后通过统一的虚实空间用户管理框架实现了跨域统一、透明安全的存储服务和对大型计算应用的支撑,这对于国家高性能计算环境的发展具有十分重要的意义。

The national high performance computing environment(NHPCE)is characterized by wide area dispersion,heterogeneous system and storage isolation autonomy,which posed great challenges to storage management and data sharing.Firstly,the concept of virtual data space system was described.Secondly,how the virtual data space system effectively reduce the cost of cross domain access through viewing-access,data sharing,computing environment docking,was analyzed.Thirdly,the virtual data space system were deeply integrated with the NHPCE by means of modularization and its functions were added to the NHPCE.Finally,the unified virtual and real space user management framework was used to achieve cross domain unified,transparent and secure storage service and the support of large-scale computing application,which is of great significance to the development of NHPCE.
