LineShine
All-CPU exascale supercomputer at the National Supercomputing Center in Shenzhen, ranked first on the TOP500 in 2026.
Coverage · About LineShine
ORNL's first Genesis Mission supercomputer misses the top ten even at perfect Linpack efficiency. No US system has published the FP64 to challenge China's LineShine.
Simulation still fills the world's research supercomputers. Funding and vendor roadmaps have tilted to AI, and some practitioners feel pressure to pitch their machines that way.
Dongarra, Hoefler, and Matsuoka now ask whether supercomputing needs GPUs at all, and the CPU-only machine atop the Top500 is their test vehicle.
LineShine, the system NSCC Shenzhen unveiled at the top of the 67th list, sustained 2.198 exaflops on LINPACK and took #1 on HPCG with zero accelerators and a domestic processor, interconnect, and operating system.
