National Supercomputing Center in Shenzhen has deployed a new supercomputer called LineShine, as China pushes to strengthen domestic computing capabilities amid global competition in advanced technologies. The system delivers performance of up to 1.54 exaFLOPS and is powered by Armv9-based LX2 processors, each featuring 304 CPU cores. Unlike many modern supercomputers that depend heavily on GPUs for large-scale parallel computing, LineShine primarily relies on CPUs for general computing and coordination tasks.
The LineShine system consists of 20,480 computing nodes, each equipped with two Armv9-based LX2 processors. The system includes 40,960 processors and more than 2.45 million CPU cores. The nodes are connected through a high-speed interconnect network called Lingqu, which adopts a dual-plane multi-rail fat-tree topology and provides bandwidth of 1.6 Tb/s per node. [Jiwei, in Chinese]
