China\'s LineShine supercomputer regains world top spot with homegrown technology

China has regained the top spot in global supercomputer performance for the first time since 2017, achieving the world’s No. 1 result without GPUs despite U.S. semiconductor and AI technology restrictions. The National Supercomputing Center’s LineShine recorded 2.198 EFlops, topping Lawrence Livermore National Laboratory’s El Capitan at 1.809 EFlops. TOP500 said LineShine is the first sustainable double-precision 2-exaflop-class system built using CPUs only.

Naver team builds 4,000 Nvidia Blackwell B200 GPU cluster, says AI model development 12 times faster

Naver said on Jan. 8 it has completed an AI computing cluster based on 4,000 Nvidia B200 Blackwell GPUs. The company said the new “B200 4K cluster” is comparable in computing scale to leading TOP500 supercomputers. Internal simulations showed training a 72 billion-parameter model could be cut from about 18 months on an A100-based 2,048-GPU setup to about 1.5 months, improving training efficiency by more than 12 times.
