超级计算机“神威·太湖之光”世界最快(中国这五年的世界之最④)

2017-08-29 03:20:58   中国青年网

6月19日,在德国法兰克福全球超级计算大会上,中国“神威·太湖之光”荣登全球超级计算机500强榜首。自2016年6月问世以来,这是它第三次获评“全球最快超级计算机”,由此实现“三连冠”。

“神威·太湖之光”由国家并行计算机工程技术研究中心,使用中国自主芯片研制。在被称为“国之重器”的超级计算机领域内,“神威”标志着我国超算科技取得了多方面关键性突破,为解决经济、社会治理等一系列重大挑战提供了技术手段,对提升综合国力具有战略意义。

“神威”到底有多快?它有三个“世界第一”指标:系统峰值性能每秒12.5亿亿次,持续性能每秒9.3亿亿次,性能功耗比每瓦特60.5亿次。据了解,其1分钟的计算能力,相当于全球72亿人同时用计算器不间断计算32年。

速度领先了世界,应用能力也在加速跟进,超级计算的速度优势正转化为应用优势。去年11月,基于“神威·太湖之光”的“千万核可扩展全球大气动力学全隐式模拟”应用项目,获国际高性能计算应用领域最高奖——“戈登贝尔奖”,填补中国超算应用领域在这个奖项的获奖空白。

更深层次上,“‘神威·太湖之光’对我国科技创新和经济发展具有十分重要的作用。”国家超级计算无锡中心副主任付昊桓说。依托“神威·太湖之光”,中国完成百万核规模的全球10公里高分辨率地球系统数值模拟;2周完成常规10个月计算量的上海药物筛选和疾病机理研究……据了解,一年来,“神威”已涉及气候气象、先进制造、航空航天、高能物理、生命科学等19个应用领域,支持国家重大科技应用、先进制造等领域解算任务几百项,共计完成200多万项作业任务。
