高能同步辐射光源科学数据处理平台规划与设计

The Design of Science Data Platform for High Energy Photon Source

【目的】高能同步辐射光源(HEPS)是我国“十三五”期间优先建设的、为国家的重大战略需求和前沿基础科学研究提供技术支撑平台的国家重大科技基础设施,开展超高空间分辨、时间分辨、能量分辨的高通量同步辐射实验。其一期建设的十五条光束线实验站,预计平均每天产生200TB的原始实验数据,峰值可达每天500TB。这些实验数据需要得到存储、共享,并能够进行准确实时的处理与分析。【方法】科学数据处理平台包括基础设施、科学软件、网络、计算、存储、公共信息服务等系统。【结果】该平台将为HEPS设施、科研人员、工程技术人员以及用户提供包括设数据传输、数据存储、数据分析、数据共享、科研协同等在内的网络、计算、存储等基础设施能力,以及提供科学软件、通用软件、通用信息系统和网络信息安全服务等。

[Objective]High Energy Photon Source(HEPS)is one of the key scientific and technological infrastructure projects in China.It supplies an important platform for original and innovative research in basic science and engineering to meet the demands of national significant strategy,on which high-throughput synchronous radiation experiments can be carried out,including ultrahigh spatial resolution,time resolution and energy resolution X-ray diffraction experiments.It is estimated that over 200TB on average and even 500TB at maximum raw data will be produced every day from the 15 public beamlines and stations in the first construction phase.These experimental data will be permanently stored in a central storage,shared with research members,and can be near real-time processed and analyzed.[Methods]The science data platform consists of multiple systems,including IT infrastructure,scientific software,network,computing unit,storage device and public information service.[Results]It will provide scientific researchers,engineers and users with networks,computing units,storage devices,and other infrastructure capabilities for scientific research collaboration,data transmission,data storage,data analysis,data sharing and services for scientific software,general software,general information system,and information security etc.
