We studied high performance data analysis for large format astronomical data. We tried to find methods and enviroments suitable to quick extraction of astronomical information from raw image data.We performed experiments of the first stage analysis, i.e. reduction process, which spends a lot of time with large amount of I/O.We use IRAF as the reduction software which is the most popular data reduction/analysis package in the Optical/IR astronomy. We found that the configuration and settings of magnetic disks, the efficiency and number of I/O buses, and quantity of main memory are critical factors for the process speed. These results will be a guideline of the system configuration for high performance data reduction.We also examined several problems in the analysis of the data of Hubble Space telescope (HST), Sloan Digital Sky Survey (SDSS), Okayama Astrophyisical Observatory 188cm telescope, and Subaru Telescope. We investigate the combination with data arhcive systems, image browsers, and astronomical database, which promote data analysis. We discussed with many astronomers and reserchers of other fields on the future of data analysis.

我们研究了大格式天文数据的高性能数据分析。我们试图找到适合从原始图像数据中快速提取天文信息的方法和环境。我们进行了第一阶段分析的实验，即减少过程，该过程花费了大量时间与大量I/O。我们使用IRAF作为降低软件，这是光学/IR IR天文学中最受欢迎的数据减少/分析包。我们发现，磁盘的配置和设置，I/O总线的效率和数量以及主内存数量是过程速度的关键因素。这些结果将是用于降低高性能数据的系统配置的指南。我们还研究了哈勃太空望远镜（HST），斯隆数字天空调查（SDSS），奥基马天体天文台188CM望远镜和斯巴鲁望远镜的数据分析中的几个问题。我们研究了促进数据分析的数据库系统，图像浏览器和天文数据库的组合。我们与其他领域的许多天文学家和研究者讨论了数据分析的未来。
