Still waiting for Exascale: Japan’s Fugaku outperforms all competition once again
FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.— The 58th annual edition of the TOP500 saw little change in the Top10. The Microsoft Azure system called Voyager-EUS2 was the only machine to shake up the top spots, claiming No. 10. Based on an AMD EPYC processor with 48 cores and 2.45GHz working together with an NVIDIA A100 GPU and 80 GB of memory, Voyager-EUS2 also utilizes a Mellanox HDR Infiniband for data transfer.
While there were no other changes to the positions of the systems in the Top10, Perlmutter at NERSC improved its performance to 70.9 Pflop/s. Housed at the Lawrence Berkeley National Laboratory, Perlmutter’s increased performance couldn’t move it from its previously held No. 5 spot.
Fugaku continues to hold the No. 1 position that it first earned in June 2020. Its HPL benchmark score is 442 Pflop/s, which exceeded the performance of Summit at No. 2 by 3x. Installed at the Riken Center for Computational Science (R‑CCS) in Kobe, Japan, it was co-developed by Riken and Fujitsu and is based on Fujitsu’s custom ARM A64FX processor. Fugaku also uses Fujitsu’s Tofu D interconnect to transfer data between nodes.
In single or further-reduced precision, which are often used in machine learning and A.I. application, Fugaku has a peak performance above 1,000 PFlop/s (1 Exaflop/s). As a result, Fugaku is often introduced as the first “Exascale” supercomputer. (…) Weiterlesen »
