ORNL's Jaguar Supercomputer is World's Fastest
OAK RIDGE - After a year at No. 2, Oak Ridge National Laboratory's Jaguar has emerged as the world's fastest computer, according to the Top500 rankings unveiled today.
The newly updated Cray XT5 system passed a benchmark test at 1.759 quadrillion mathematical calculations per second - or 1.759 petaflops. That easily surpassed the IBM Roadrunner at Los Alamos National Laboratory in New Mexico. Roadrunner's qualifying speed, 1.04 petaflops, actually declined slightly from the last ranking because of a reconfiguration of the computer.
