站长搜索讯 8月26日消息,最近,美国田纳西州橡树岭国家实验室将迎来2017 Summit新超级计算机系统,该系统采用了新一代的IBM Power构架服务器,并搭载了NVIDIA NVLink高速GPU互连技术,性能达到每秒百亿亿次级,将同时负责劳伦斯-利佛摩尔国家实验室的研究计算工作,并执行美国国家核安全任务。然而,橡树岭实验室的老超算Titan II要何去何从呢?毕竟,该设备曾经是美国排名第二的超级计算机,耗资数百万美元,研究周期长达数年

站长搜索讯 8月26日消息,最近,美国田纳西州橡树岭国家实验室将迎来2017 Summit新超级计算机系统,该系统采用了新一代的IBM Power构架服务器,并搭载了NVIDIA NVLink高速GPU互连技术,性能达到每秒百亿亿次级,将同时负责劳伦斯-利佛摩尔国家实验室的研究计算工作,并执行美国国家核安全任务。

然而,橡树岭实验室的老超算Titan II要何去何从呢?毕竟,该设备曾经是美国排名第二的超级计算机,耗资数百万美元,研究周期长达数年。实验室方面给出的解决方案非常简单:既然已经有新的,那么就把旧的碾碎吧!

来自新墨西哥州的计算机架构师Douglas Doerfler就曾经亲眼目睹过碾碎超算的场景,当时的主角是红色风暴超算系统。据他回忆,碾碎一台超级计算机和旧车处理厂解决那些老爷车没什么区别,总之就是噼里啪啦一阵乱响,一切就结束了。

之所以对旧超算系统如此“绝情”,原因有几个。其一,一般来说,超级计算机的计算内容大多涉及国家机密,不可能像卖旧货一样随便就打发给别人;其二,超级计算机的成本主要来自研发费用,而具体的设备制造费用只占到不大的一部分,旧超算又耗电管理又麻烦,既然有了新超算,再造一台也比用旧的便宜。其三,超级计算机的零配件大多是定制产品,维修非常费时费工,旧了就经常坏,坏了不如换新的。

据美国洛斯阿拉莫斯实验室的工作人员介绍,该机构的超算寿命一般只有3至5年左右,还比不上一些家用电脑的寿命。当然,销毁一台超算之后,其中大部分黄金、铜、铝等金属将回收,实验室顺便还可以卖废铁,补贴超算惊人的电费。此外,电源、冷却器等部件一般是可以装到新超算上的。

一般来说,一台超算的回收利用率不足10%,而被销毁的大部分材料就成了人类科技进步的铺路砖。
