The updated ranking of the world's fastest supercomputers has brought unexpected changes. The "LineShine" system, developed by the China National Supercomputing Center, has topped the list as the fastest computing system in the world.
Citing "Engadget", Oxu.Az reports that with this achievement, China has regained the global supercomputer lead for the first time since 2017.
"LineShine" surpasses the previous leader, "El Capitan", which operates at the Lawrence Livermore National Laboratory in the US with a performance of 1,809 exaflops.
Unlike most modern supercomputers, "LineShine" does not use graphics processing units (GPUs). Instead, it is built on a unique architecture based on specially designed central processing units (CPUs). The system consists of special processors with 304 cores each, totaling 13.79 million cores. The processors run at 1.55 GHz and are interconnected via a high-speed data network.
The system's power consumption is approximately 42.2 megawatts (MW). However, its computational efficiency is 52.07 gigaflops per watt, one of the highest for systems of this scale. In contrast, the previous leader "El Capitan" used a hybrid architecture with GPUs for high performance. China's new approach favors scaling up CPU-based computing.
