Supercomputers

    One definition for a supercomputer is “the most powerful computer available at any given time.” These machines are used to solve complex problems such as the design of a supersonic aircraft, modeling of global climates, the structure of oil-bearing formations within the Earth, the molecular design of new drugs, or the prediction of complex financial behavior in securities markets. Two of the first supercomputers were the Control Data Corporation CDC 6600 and CDC 7600. Both were developed by Seymour Cray, one of the founders of CDC. In 1972, Cray left to found Cray Research, Inc., and in 1976 developed the Cray-1, generally acknowledged to be the first true supercomputer.

     The Cray-1 used high-speed emitter coupled logic (ECL), the fastest (and most power hungry) logic circuits available at the time. The computer was packaged as a 6.5 ft. high cylinder surrounded by a circular seat. Each circuit board was mounted on a copper heat exchanger through which liquid freon was circulated. The total power consumption of the computer was 128 KW! Processing speed was 130 MFLOPS (millions of floating-point operations per second). In all, 63 Cray-1 computers were sold (at a cost of $5.1 million each).
