上周,在利佛莫尔国家实验室的一间灯火通明的屋子里,造价为1760万美元的克雷2号开始运行,从而使计算机进入了一个新的时代。克雷2号保持两个世界之最。一是内部储存能力最大,达20亿个位,二是运算速度最快,每秒运算12亿次,比克雷一号快6～12倍,比一般计算机快4～5万倍。克雷2号是目前超大型计算机中的佼佼者,它能将一些旷日费时的计算工作大大缩短,极大地裨益于从事科研与设计工作的科学家与工程师.负责计算机运行的布彻斯说,在1952年需一年完成的计算工作现在只要一秒钟就能完成。
Last week, at a brightly lit room in Livermore National Laboratory, a $ 17.6 million Cray 2 started operating, turning the computer into a new era. Cray No. 2 to maintain the best of both worlds. First, the largest internal storage capacity of up to 2 billion bits, the second is the fastest computing speed, computing 1.2 billion times per second, faster than the Keke 6 to 12 times faster than the average computer 4 to 50,000 times. Creole 2 is the current leader in supercomputers that can significantly reduce some of the time-consuming computations and greatly benefit scientists and engineers working on scientific research and design.Buchs, who runs the computer, The calculations that took one year to complete in 1952 are now completed in only one second.
