我国下一代超算原型机开建 比神威·太湖之光快8倍

2017-06-23 08:38:00   新华社

新华社6月22日消息,我国下一代神威E级原型机日前在山东济南开工建设,这一原型机计划2018年6月竣工投用。神威E级计算机将拥有每秒百亿亿次的数学运算能力,性能将比目前全球最快的超级计算机(神威·太湖之光,每秒12.5亿亿次)高出8倍。

在本月19日发布的全球超算500强榜单中,美国20年来首次无缘前三。但中国超算专家对此仍保持警觉。中国计算机学会高性能计算专委会秘书长、国家超算济南中心主任张云泉认为,这是美国超算发展的低潮,也可能是触底反弹的开始。他透露,2018年下半年,美国将开始推出全新研制的“北极光”超算,运算速度可以达到18亿亿次(即180P,P为超级计算机运算单位,意为每秒千万亿次)。美国能源部已宣布未来三年给六家科技公司拨款2.58亿美元,协助这些公司开发下一代超级计算机。

目前最快的超算“神威·太湖之光”

下一代神威E级原型机计划2018年6月竣工投用

新华社记者从国家超级计算济南中心获悉,我国下一代神威E级原型机日前在山东济南开工建设,这一原型机计划2018年6月竣工投用。目前,青岛海洋科学与技术国家实验室、国家超级计算济南中心正联合申请神威E级计算机。一旦获批,这一型号超级计算机有望2020年落户山东。

另据《科技日报》,作为全球第一台运行速度超过十亿亿次/秒的超级计算机,“神威·太湖之光”超级计算机计算能力“运算1分钟相当于200多万台普通电脑的运算能力,也相当于72亿地球人同时用计算器不间断计算32年。”但在山东省科学院计算中心(国家超算济南中心)副主任潘景山看来,E级计算机的运算速度可达“神威·太湖之光”的8倍多——每秒运算将达到百亿亿次。

从“天河二号”首次登顶世界最快超级计算机宝座开始,中国超算已经斩获全球超级计算机500强榜单的“九连冠”。

“九连冠”后需冷静,美国或将触底反弹

本次全球TOP500榜单,美国罕见被挤出前三名。张云泉认为,这是美国超算发展的低潮,也可能是触底反弹的开始。他透露:2018年下半年,美国将开始推出全新研制的“北极光”超算,运算速度可以达到180P(P为超级计算机运算单位,意为每秒千万亿次)。所以从2018年到2020年,美国或将重新夺回TOP500的冠军宝座,甚至可能会出现几连冠的情况。
