Japan’s Fugaku Retains Title as World’s Fastest Supercomputer for fourth consecutive term

The supercomputer Fugaku, jointly developed by RIKEN and Fujitsu, has successfully retained the top spot for four consecutive terms in all four of the major high-performance computer rankings. This includes the TOP500 list as well as the HPCG, a performance ranking for computing methods often used for real-world applications, HPL-AI, which ranks supercomputers based on their performance on single- and half-precision computing typically used in artificial intelligence applications, and the Graph 500 ranking, which ranks systems based on graph analytic performance, an important element in data-intensive workloads.

The results this time were made with Fugaku’s full complement of 158,976 nodes fit into 432 racks. On the Top500, it achieved a LINPACK score of 442.01 petaflops. On HPCG, it scored 16.00 petaflops, and on HPL-AI it gained a score of 2.004 exaflops. The top ranking on Graph 500 was won by a collaboration involving RIKEN, Kyushu University, Fixstars Corporation, and Fujitsu. It earned a score of 102,955 gigaTEPS. The results of the rankings were announced on November 15 at the SC21 High-Performance Computing Conference.
