A Cray SuperComputer Comes To The University Of Toronto
Beginning of paper
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

.... 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 Cray performs everything in one clock cycle. This power is measured in
Millions of Floating Point Operations Per Second (MFLOPS) - which is to
say the rate at which floating-point operations can be performed. The Cray
MFLOPS vary as it does many activities, but a rate of up to 210 MFLOPS
(per CPU) can be a ....
