The Cray X-MP/22 manufactured by Cray Research Incorporated (CRI) of Minneapolis, Minnesota was delivered and installed at the U of Toronto this September. The Cray is a well respected computer - mainly for its extremely fast rate of mathematical floating-pointcalculation. As the university states in its July/August computer magazine "Compu ...

... the '22'. The Cray operates at a clock rate of 105 MHz (the regular, run-of-the-mill IBMPC has a clock rate of 4.77 MHz). By quick calculations, you would be led to believe the Cray is only about 20 times faster that the PC. Obviously, this is not the case. The Cray handles data considerably differently than the PC. The Cray's circuits permit an array of data (known as a 'vector') to be processes as a SINGLE entity. So, where the IBMPC may require several clock cycles to multiply two numbers, the Cr ...
