摘要
2008年11月,中国高性能计算机TOP100排行榜和世界超级计算机TOP500排行榜先后揭晓。由于系统性能的快速提高,排行榜中的高性能计算机更新很快。最新的TOP500排行榜上出现了运算速度达每秒千万亿次的系统。而TOP100排行榜也首次出现了运算速度超过百万亿次的系统。本文从总体性能、技术演进、能效、国家分布、制造商格局和应用领域等角度,对国内外高性能计算机的发展现状进行对比分析,并对其发展趋势进行预测,以图对我国高性能计算科学技术的发展提供借鉴。
The TOP100 HPCs of China and the TOP500 ones of the world have been released in November 2008. There are great changes on both lists because of quickly enhanced performance. The systems breaking the petaflop/s barrier appear on the TOPS00 list ,and the ones exceeding 100 teraflop/s come forth on the TOP100 list. From the perspective in general performance, technical approach, power consumption, countries, vendors and application areas, the article comparatively analyzes the status quo of HPC of both China and the world, and forecasts the trend ,so as to provide references for development of HPC technology of China.
