2014年中国高性能计算机发展现状分析与展望

State-of-Art Analysis and Perspectives of 2014 China HPC

本文根据2014年11月发布的中国高性能计算机TOP100排行榜的数据,对国内高性能计算机的发展现状从总体性能、制造商、行业领域等方面进行了深入分析。我们发现,由于天河二号超级计算机的发布,中国TOP100的平均Linpack性能已经从两年前的落后一年变为比国际TOP500平均Linpack性能高的局面,且TOP100的入门性能门槛也第一次超过TOP500。在此基础上,根据十三届排行榜积累的性能数据和能够得到的其他公开历史数据,对未来几年中国大陆高性能计算机的发展趋势进行了分析预测。根据新的数据和实际情况,经修正后我们认为,累计Linpack性能将在2015年到2016年间达到100Petaflops,比我们原来预期的晚;峰值100Petaflops的机器将在2015年到2016年间出现;峰值Exaflops的机器将在2019年到2020年间出现,比我们原来预期的晚2年。单台机器峰值超过累计Linpack性能的情况出现在2018到2019年间。

In this paper, we first introduce the background of China HPC TOP100 rank list. Then we give the total performance trend of China HPC TOP100 and TOP 10 of 2014. Followed with this, the performance, manufacturer, and application area of 2014 China HPC TOP100 are analyzed in detail. We found out that the average Linpack performance of China TOP100 has surpassed the TOP500 quickly with the release of Tianhe-2 again. Based on public available historical data and TOP100 supercomputers peak performance data from 1993 to 2014 in China mainland, we predict the future performance trend of China HPC TOP100. We found out that the total Linpack performance of China HPC TOP100 rank list will be over 100Petaflops between 2015 and 2016, delayed for one year; supercomputer with 100Petaflops peak performance will appear between 2015 and 2016, and supercomputer with Exaflops peak performance will appear between 2019 and 2020, delayed for two years. The peak performance of one system surpass the total Linpack performance of TOP 100 will appear between 2018 and 2019.
