A Chinese machine clocked in as the second-fastest on the latest list of the world's 500 fastest supercomputers—making the country a serious challenger to American dominance in the industry.
The speedy Chinese computer, called Nebulae, is based at the National Supercomputing Center, in Shenzhen. It reached a computing speed of 1.27 petaflops, a rate of one quadrillion calculations per second. The machine is theoretically capable of running at almost three petaflops, the highest speed ever. The Cray Jaguar supercomputer, at the Oak Ridge National Laboratory, in Tennessee, remains the world's fastest machine on record at 1.75 petaflops, though its theoretical peak performance is lower than Nebulae's.
