What are Flops?Date: 02/25/2001 at 09:15:15 From: John McCormick Subject: What Is A Flop? Hello Dr. Math, I really need to know what a flop is, and what a teraflop is. My teacher told me to go to this site, but I can't find it anywhere. Can you please help me? Date: 02/25/2001 at 09:50:42 From: Doctor Mitteldorf Subject: Re: What Is A Flop? Dear John, It's not flop, it's flops. Flops stands for "FLoating-point Operations Per Second," and we don't use "flop." A computer has different ways of representing numbers internally. Integers are the easiest, but they have to be whole numbers between -32,768 and 32,767. Integers multiply and divide quickly. "Floating point" numbers are the opposite. They're numbers that can have a decimal point as part of them, and a power of ten, which is the way the computer can tell 75.0 from 0.075 or 750,000,000. Flops are a measure of computer speed. A "1 flops" computer can perform one multiplication of floating point numbers in a second. A modern computer can multiply billions of floating point numbers in one second. Each billion multiplications in a second is a "gigaflops." A thousand billion multiplications per second is a "teraflops," and I think the biggest of today's computers can do that. - Doctor Mitteldorf, The Math Forum http://mathforum.org/dr.math/ |
