Supercomputer speed, US “Frontier” consecutive wins “Fugaku” maintains second place

The world ranking “TOP 500” of the calculation speed of supercomputers was announced at an international conference held in Dallas, Texas on the 15th Japan time, and “Frontier” of Oak Ridge National Laboratory was the top following the previous May. rice field. Last time, the aircraft achieved the “exa-class”, which means 100 quintillion times per second (Kyo is 10,000 times 1 trillion) for the first time in history. RIKEN’s “Fugaku” defended its second place.

 TOP500 competes twice a year for the processing speed of performance evaluation programs. In the latest version, Frontier, developed by the US Department of Energy with Cray Inc., etc., is 110 2000 trillion times per second. This was followed by 44 quadrillion times of Fugaku. The third place is also the same as last time, “Lumi” installed in Finland by the European High Performance Computing Consortium, but expanded the system and doubled the speed to 30.91 trillion times.

 Of the top 500, China has the most with 162 units. This was followed by 127 from the US, 34 from Germany, 31 from Japan and 24 from France. There are reports that China has already developed multiple exa-class supercomputers, although it has not yet applied for the TOP500.

 Japan was overtaken by China and the United States after the predecessor “Kei” won consecutive titles in 2011. In June 2020, he took the lead at Fugaku for the first time in eight and a half years, and won four consecutive titles until November last year.

 Fugaku achieved first place for the sixth consecutive term in the “HPCG”, which competed for calculation speed suitable for industrial use, and the “Graph 500,” which competed for graph analysis performance, which were announced at the same time as the TOP500. It came in third in HPL-AI, an index of computation used for deep learning of artificial intelligence (AI).

 Fugaku was jointly developed by RIKEN and Fujitsu. It was installed on the former site of Kyoto at the RIKEN Center for Computational Science (Kobe City), and after trial use from April 2020, it started full-scale operation in March last year. In addition to the Ministry of Education, Culture, Sports, Science and Technology’s “Result Creation Acceleration Program,” it is being used for general public offerings and important national issues.

 RIKEN plans to strengthen research and development to combine conventional supercomputers with futuristic “quantum computers” that make use of the “quantum” properties of the atoms and electrons that make up matter. In August, under contract from the Ministry of Education, we began research on the performance and functions required for the successor to Fugaku.

 Satoshi Matsuoka, director of the center, said, “Fugaku has demonstrated world-class comprehensive capabilities. It has achieved the SDGs (Sustainable Development Goals of the United Nations) and Society 5.0 (for a super smart society), and has solved various problems. In order to solve the problem, we can easily realize a wide range of high performance.The design concept was correct.We aim to use our experience to conduct research and development for the next generation of high-performance computing.”
