WASHINGTON: A Chi­n­ese machine has seized the title of world’s most powerful supercomputer, ending nearly a decade of US dominance and underscoring Beijing’s drive to build advanced computing power with homegrown technology. The system, called Lin­e­Shine, topped the closely watched TOP500 ranking unveiled at the major computing ISC conference in Hamburg, Germany. It is the first time since 2017 that a Chinese supercomputer has led the list, which has been published twice a year since 1993 and serves as an informal scoreboard for the world’s computing superpowers.
