The TOP500, which publishes its biannual ranking of the world's supercomputers, has announced its 55th ranking for June.
Fujitsu and RIKEN developed a domestic supercomputer called "Fugaku," which competed for the top spot in terms of computing performance. High Performance Linpack (HPL) results were 415.5 PFLOPS and 148.8 of IBM's Summit, which came in first place last time (November 2019) and second this time around. The result shows a huge performance difference, about 2.8 times more than the PFLOPS.
Third place was also taken by IBM's Sierra with 94.6 PFLOPS (previous second place), and fourth place went to China's Sunway 93 PFLOPS (3rd place last time) with TaihuLight (Shenwei Taihu No Light), followed by 5th place with China's Tianhe-2 (Tianhe-2) with 61.4 PFLOPS (4th last time) and The rankings are moving back.
The supercomputer "Selene" announced today by NVIDIA is in 7th place. The performance was 27.58 PFLOPS. The system is based on the DGX A100 with an Ampere architecture and AMD's 64-core CPU. It is powered by EPYC 7742 and is in operation at the U.S. National Institutes of Health and the University of Texas at Austin.
Fugaku is powered by the Fujitsu-developed A64FX CPU, which uses the Arm architecture, and the node Tofu (Torus fusion) interconnects are used for the connection between the Arm processor and the This is the first time for the A64FX to be ranked No.1 in the TOP500. Arm v8.2-A SVE with 48 cores + 2 assistant cores as compute nodes, IO and compute It has 48 cores + 4 assistant cores as nodes and boasts a theoretical calculation performance of 2.7 The peak performance of the A64FX-equipped Fugaku is 1 EFLOPS ( Exaflops) and beyond.
