China unveils GPU-free LineShine supercomputer with 2.45 million domestic CPU cores
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 genera
China's National Supercomputing Center in Shenzhen has launched a new supercomputer named LineShine, designed to enhance the nation's domestic computing power. This system boasts a peak performance of 1.54 exaFLOPS and is built using over 2.45 million CPU cores from domestically produced Armv9-based LX2 processors. Notably, LineShine distinguishes itself by relying primarily on CPUs for its computing tasks, rather than the GPUs commonly found in other advanced supercomputers. The supercomputer utilizes 20,480 nodes, each housing two LX2 processors, and is interconnected by a high-speed Lingqu network.
The development of LineShine signifies China's strategic move towards self-sufficiency in high-performance computing, reducing reliance on foreign technology amidst global competition.
