The US has retained its top position as the producer of the fastest supercomputers in the world, with China still second after not introducing any new machines in recent months.
Summit and Sierra, two IBM-built supercomputers, maintained their top positions for the US, followed by two Chinese systems, the Sunway TaihuLight and the Tianhe-2A, which are installed in Wuxi and Guangzhou, respectively. Frontera, located at the University of Texas, is the only new supercomputer in the top 10, according to the latest Top500 list.
