Abstract

天文数据处理是天文研究的一个重要环节。随着新一代望远镜功能与观测能力的快速发展,在观测地点构建高性能实时计算平台,快速完成数据的分析与处理是一种趋势。针对明安图射电频谱日像仪和明安图观测站实时数据处理系统的建设要求,系统研究了基于OpenStack的本地云实现方法与系统自动管理模式,提出了动态进行计算节点启停的方法,并进行了实际测试。实验表明,该模式完全可以满足天文数据处理的需求,并且比传统的静态分配计算资源的数据处理方法更高效,可以有效地节省能源开销,降低观测成本,对未来天文台站高性能计算平台的建设有一定的参考价值。

Other Abstract

Astronomical data processing is a very important part of astronomical research. With the rapid growth of function and observation capability of the new generation of telescopes,building a high performance real-time computing platform in observing sites and handling the data quickly have become a trend. Based on the real-time data processing system construction requirement of MUSER,this paper has systematically studied the implementation method based upon OpenStack local cloud and automation management pattern. We propose a strategy which can open or close compute nodes automatically and the experiments are carried out.Experiments show that this pattern can meet the needs of astronomical data processing completely and it is more efficient than other traditional data processing methods of static computing resources allocation. At the same time,it can efficiently save our energy bills and reduce the observing costs. This pattern has certain value for reference to build a high-performance computing platform for observatories in the future.
