China has taken the world’s quickest supercomputer crown for the primary time since 2017. LineShine from the nation’s Nationwide Supercomputer Middle hit 2.198 Exaflops of efficiency, beating the previous champ El Capitan (1.809 Exaflops), situated at Lawrence Livermore Nationwide Laboratory within the USA. Lineshine, a beforehand unlisted machine, is the primary supercomputer to exceed two exaflops of “sustained double-precision efficiency utilizing CPUs solely,” in accordance with Top500.org.
China’s new machine was capable of beat its US counterpart regardless of expertise embargoes as a result of it would not depend on GPUs like different main fashions. As a substitute, it is designed round a {custom} 304-core processor, with 13.79 million cores working at 1.55GHz and linked by a proprietary interconnect. It attracts round 42.2 megawatts of energy, for an effectivity of 52.07 Gigaflops per watt. “It is a formidable system,” Top500 organizer Dr. Jack Dongarra informed The New York Times. “They upped us by growing a system that isn’t reliant on GPUs.
Although China managed to grab the highest spot, the brand new rating now boasts 5 methods beating the exascale threshold, with one in China, three within the US and one in Germany. Oak Ridge Nationwide Laboratory’s Frontier strikes to No. 3 at 1.353 Exaflop whereas Aurora, at Argonne Nationwide Laboratory, holds No. 4 at 1.012 Exaflops. Jupiter Booster, on the Jülich Supercomputing Centre strikes to No. 5 at precisely one Exaflop.
Top500 famous a substantial amount of architectural range with this yr’s checklist, with totally different supercomputer fashions utilizing Intel, AMD, NVIDIA and different structure. “There isn’t a single dominant expertise path to leadership-class computing; as an alternative, distributors are pursuing a wide range of CPU, GPU, APU, and custom-accelerator approaches,” Top500 wrote.
China has typically stored its supercomputer designs underneath guard as a consequence of authorities restrictions. Nevertheless, LineShine was developed with out public funding, so its designers felt that they may submit it to Top500’s checks with out challenge, in accordance with the NYT. The corporate did not reveal sure particulars like which firm manufactured the CPUs or the kind of chip expertise used.
