King of Speed - Fastest Supercomputer

To put the computer’s speed in perspective, if every one of the 6 billion people on earth used a hand-held computer and worked 24 hours a day it would take them 46 years to do what the Roadrunner computer can do in a single day.

The interconnecting system occupies 6,000 square feet with 57 miles of fiber optics and weighs 500,000 pounds. Although made from commercial parts, the computer consists of 6,948 dual-core computer chips and 12,960 cell engines, and it has 80 terabytes of memory.

The cost: $100 million.

Turek said the computer in a two-hour test on May 25 achieved a “petaflop” speed of sustained performance, something no other computer had ever done. It did so again in several real applications involving classified nuclear weapons work this past weekend.

A “flop” is an acronym meaning floating-point-operations per second. One petaflop is 1,000 trillion operations per second. Only two years ago, there were no actual applications where a computer achieved 100 teraflops — a tenth of Roadrunner’s speed — said Turek, noting that the tenfold advancement came over a relatively short time.
