# HOW FAST IS FASTEST?

The K Computer developed by Riken Advanced Instutute for Computational Science, Japan, and Fujitsu has become the fastest supercomputer with a calculating speed of 10 Petaflops per second. Ten Pflops is equal to 10 quadrillion floating point operations per second. If that doesn’t make sense, here is a translation: it is the amount of calculation over 16 and a half days done by all 7 billion people in the world, with each person posting one calculation result every second. And the K Computer does all this in one second. Talk about fast!
