US retakes first place from Japan on Top500 supercomputer rating

America is on high of the supercomputing world within the Top500 rating of essentially the most highly effective programs. The Frontier system from Oak Ridge Nationwide Laboratory (ORNL) operating on AMD EPYC CPUs took first place from final yr’s champ, Japan’s ARM A64X Fugaku system. It is nonetheless in the combination and testing course of on the ORNL in Tennessee, however will finally be operated by the US Air Pressure and US Division of Vitality.

Frontier, powered by Hewlett Packard Enterprise’s (HPE) Cray EX platform, was the highest machine by a large margin, too. It is the primary (identified) true exascale system, hitting a peak 1.1 exaflops on the Linmark benchmark. Fugaku, in the meantime, managed lower than half that at 442 petaflops, which was nonetheless sufficient to maintain it in first place for the earlier two years.  

Frontier was additionally essentially the most environment friendly supercomputer, too. Working at simply 52.23 gigaflops per watt, it beat out Japan’s MN-3 system to seize first place on the Green500 listing. “The incontrovertible fact that the world’s quickest machine can also be essentially the most power environment friendly is simply merely wonderful,” ORNL lab director Thomas Zacharia mentioned at a press convention.

Different machines within the TOP10 embrace one other HPE Cray EX system set up at EuroHPC in Finland (151.9 petaflops), the IBM-built Summit system utilizing 22-core Energy( CPUs and NVIDIA Tesla V100 GPUs (148.8 petaflops) and Lawrence Livermore’s Sierra, a smaller-scale model of Summit that hit 94.6 Pflop/s.

China held two top-ten spots with its Sunway TaihuLight from the Nationwide Analysis Heart of Parallel Pc Engineering & Know-how (NRCPC) and Tianhe-2A constructed by China’s Nationwide College of Protection Know-how (NUDT). Nevertheless, China is rumored to already haven’t any lower than two exascale programs (in response to the Linmark benchmark) on recent Sunway Oceanlite and Tianhe-3 programs. Resulting from the present state of semiconductor politics, nevertheless, China is reportedly not revealing any recent benchmarks or vital advances.
