China’s Lineshine ‘came out of nowhere’ to grab title of most powerful computer in the known universe
The International Supercomputer Conference in Hamburg was the perfect platform for Lineshine (or Língshèng 灵晟) to, well, shine, as it received the crown of the world’s most powerful computer ever built.
It smashed the previous TOP500 record held by El Capitan, the US supercomputer built in 2024 by HPE for the National Nuclear Security Administration (NNSA) at the Lawrence Livermore National Laboratory (LLNL).
Unlike the latter, Lineshine uses CPU power only rather than APU or GPUs, a remarkable feat given the prevalence of these technologies. Only another supercomputer in the top 10, the Arm-powered Fugaku supercomputer, falls in that category.
Details shared by Lu Yutong, the chief designer of Lineshine show that it is powered by more than 13.7 million ARMv9 cores spread over 90 racks and 45,360 CPUs.
