Lead engineer Don Grice of IBM inspects the world's fastest computer in the company's Poughkeepsie, NY plant. The computer nicknamed "Roadrunner" was built for the Department of Energy's National Nuclear Security Administration and will be housed at Los Alamos National Laboratory in New Mexico. IBM engineers in Poughkeepsie, N.Y., Rochester, Minn., Austin, Texas and Yorktown Heights, N.Y., worked on the computer, the first to break a milestone known as a "petaflop" -- the ability to calculate 1,000-trillion operations every second. The computer packs the power of 100,000 laptops -- a stack 1.5 miles high. Roadrunner will primarily be used to ensure national security, but will also help scientists perform research into energy, astronomy, genetics and climate change.
