China claims the world’s fastest supercomputer

China's LineShine supercomputer at the National Supercomputing Center in Shenzhen has reclaimed the title of the world's fastest supercomputer, displacing El Capitan from the TOP500 ranking despite US trade restrictions on high-powered computing components. LineShine does not use GPUs, a key component in most modern supercomputers, and the achievement is seen as a message from China to the US.
