China's 'LineShine' Named World's Fastest Supercomputer at ISC 2026, Replacing US El Capitan

11 July 2026National

China's 'LineShine' was named the world's fastest supercomputer at the 2026 ISC High Performance conference, displacing the US-based 'El Capitan' from the top spot. LineShine achieved the leading double-precision performance on the High-Performance Linpack (HPL) benchmark, the standard test used to rank supercomputers by floating-point operations per second (FLOPS). Global supercomputer rankings are tracked by the biannual TOP500 list. The Linpack benchmark measures a computer's raw mathematical processing speed.
