Oak Ridge National Laboratory’s Frontier supercomputer remained the best in the world, topping TOP500’s list of supercomputers. Also, it still remains the only system with HPL performance above one Exaflop/s. Second and third place are Japan’s Fugaku supercomputer and Finland’s LUMI, but both fall well behind Frontier.
Fugaku, now second, had held the top spot for several years before Frontier took the top spot on the June 2022 TOP500 list. LUMI placed third in June and retained that position after a hardware upgrade.
The Frontier supercomputer is based on the HPE Cray EX235a architecture and uses an AMD EPYC 64C 2 GHz processor. It has a massive 8.73 million cores and a power efficiency rating of 52.23 gigaflops/watt. TOP500 says Frontier uses gigabit Ethernet for data transfers.
Frontier is ranked 6th in TOP500’s GREEN500 (Green 500) list, as well as scoring very well in the TOP500 list. The Frontier Test & Development System (TDS), a similarly named system, also located at Oak Ridge National Laboratory, ranks second on the GREEN500 list.
