I love a supercomputer reveal, and this one's a little different than most. China's National Supercomputing Center in Shenzhen has announced its LineShine system, a machine that aims to deliver 2 exaflops of performance once it's fully constructed. That's an impressive figure, and would make LineShine one of the fastest exascale supercomputers in the world (via HPCWire ). This one, though, is planned to be an all-CPU system—in contrast to virtually all of the others on the Top500 list, which make use of AMD or Nvidia GPUs to accelerate proceedings. A pre-print of a paper entitled "Breaking the Training Barrier of Billion-Parameter Universal Machine Learning Interatomic Potentials" gives us some more potential specs of China's new toy. The paper says that the total system will be made of 20,480 computing nodes, each equipped with two Armv9-based LX2 processors. Each of those LX2 CPUs has two compute dies with 304 cores in total, which run alongside eight 32 GB HBM stacks.…
