Oak Ridge National Laboratory’s Frontier supercomputer has stayed at the top of TOP500’s list of supercomputers, making it the best in the world. In addition, it’s still the only system that has an HPL performance above one Exaflop/s. In second and third place are Japan’s Fugaku supercomputer and Finland’s LUMI, but both lag well behind Frontier.
Prior to Frontier taking the top spot in June 2022 TOP500 list, the current second-place Fugaku held the top place for several years. LUMI came into the third position in June and has held onto that position after a hardware upgrade.
The AMD EPYC 64C 2 GHz processor powering the Frontier supercomputer is based on the HPE Cray EX235a architecture. It has a staggering 8.73 million cores and a 52.23 gigaflops/watt power efficiency rating. Frontier reportedly transmits data using gigabit Ethernet, according to TOP500.
Along with ranking highly on the TOP500 list, Frontier also places sixth on the GREEN500 list of the TOP500. The second-place system on the GREEN500 list is another system with a similar name, Frontier Test & Development System (TDS), which is also based at Oak Ridge National Laboratory.
The Sunway TaihuLight won the TOP500 in June 2016, according to some early coverage by Neowin. This machine is currently ranked seventh, which may be of interest to you. Other nations have had six and a half years to create new supercomputers that can significantly outperform the TaihuLight.
