Fastest supercomputers
Top500.org
The new list of the world’s fastest computers, now in its 20th year, has China’s Tianhe-2 on top with a processing speed of 33.9 petaflops — or quadrillions of calculations per second.
Many top supercomputers are at national laboratories and are used mainly for science, such as number two Titan at Oak Ridge National Laboratory in Tennessee. In recent years, speeds have risen dramatically and operating systems have switched to Linux, prized by researchers for its flexibility. Source: Top500.org
