A supercomputer developed in Guangdong has topped the latest TOP500 list of the world's most powerful supercomputers, released at the ISC 2026 conference in Hamburg, Germany, on June 23.
Named LineShine, the system achieved a sustained performance of 2.198 exaflops in 64-bit double-precision calculations, becoming the first supercomputer to surpass the 2-exaflop threshold in this category.

Built on an all-CPU architecture and a fully domestically developed hardware and software stack, the system supports research across a wide range of fields, including climate and ocean science, energy and materials, biomedicine, industrial simulation, and artificial intelligence.
The TOP500 list is widely regarded as a benchmark of global supercomputing performance. LineShine's first-place finish marks China's return to the top of the list since 2017.
