Cray Supercomputer

                  The Cray-1 Supercomputer (designed by Seymour Cray of Cray Research, Eagan, Minnesota) was the first computer capable of performing over 100 million floating-point calculations per second. Of the many technological problems that had to be solved, one of the most important was how to remove the heat generated by the high-speed logic. This was accomplished by mounting the circuits on vertical plates that were cooled by a freon refrigeration system. Although faster machines have now been built, the Cray-1 continues to be used for mathematical studies of very complex problems, such as speech analysis, weather forecasting, and fundamental questions in physics and chemistry. The Cray-1 also leaves its mark as the informal unit of measure for newer supercomputers, some of which are now projected to equal 1,000 ‘Crays’.
