- LineShine achieved 2.198 exaflops performance, meaning it can perform more than 2 quintillion calculations per second, surpassing the previous champion, El Capitan, which reached 1.809 exaflops.
- LineShine has been ranked number one in the TOP500, marking China's return to the top since 2017.
- El Capitan, located at the US government’s Lawrence Livermore National Laboratory in California, now ranks second.
- LineShine is the first supercomputer to exceed two exaflops using only central processing units (CPUs), without relying on graphics processing units (GPUs).
- LineShine draws approximately 42.2 megawatts of power, achieving an efficiency of 52.07 Gigaflops/Watt.
- LineShine is built in Shenzhen and represents a significant achievement for China's supercomputing industry amidst foreign technology restrictions.
- China ceased submitting Linpack test results beginning in 2019 due to US government sanctions restricting access to powerful chips.
China's LineShine supercomputer has made history by achieving 2.198 exaflops of performance, making it the first supercomputer to exceed two exaflops using only central processing units (CPUs). This remarkable feat was announced during the ISC26 conference in Hamburg, Germany, where the TOP500 list was unveiled.1235678
LineShine, developed by the National Supercomputing Center in Shenzhen, has surpassed the previous record held by the US's El Capitan, which achieved 1.809 exaflops. This marks the first time since 2017 that a Chinese supercomputer has topped the rankings, highlighting China's advancements in technology despite previous sanctions that limited access to powerful chips.4
The supercomputer operates on approximately 42.2 megawatts of electricity, achieving an efficiency of 52.07 Gigaflops/Watt. It also leads the High Performance Conjugate Gradients Benchmark (HPCG) with 22.00 HPCG-Petaflop per second. Jack Dongarra, a co-founder of TOP500, noted, “This is the first time a computer with only CPUs has reached exascale.”
LineShine's success represents a significant milestone for China's supercomputing industry, showcasing its ability to build an independent hardware and software ecosystem despite foreign technology restrictions. Huang Xiaohui, the center’s deputy director, emphasized that LineShine achieved full-stack independence, from hardware to core software.
“China's LineShine has been ranked the world's fastest supercomputer, achieving 2.198 exaflops and displacing the US's El Capitan. This marks the first time since 2017 that a Chinese computer has topped the TOP500 list.”
