How fast is the new supercomputer at Oak Ridge National Laboratory? If everyone in the world performed one mathematical calculation per second, it would take 650 years to do what this machine can do in one day. In June, Cray XT supercomputer (Jaguar), a Cray Inc. system, was rated fifth-fastest in the world by researchers who track the 500 top supercomputers. The Oak Ridge lab, a Department of Energy facility, announced that it had upgraded Jaguar since then, and achieved its four-year goal of 1 quadrillion calculations per second – or 1 “petaflop” – six months ahead of schedule.
Jaguar recently achieved sustained performance of more than 1.3 petaflops while churning out calculations on superconductivity and has hit a peak speed of 1.64 petaflops, the lab said.
