The TOP500 and HPCG have ranked supercomputers in terms of computational performance for solving a system of linear equations. Following the announcement of measurements on the world's leading 15 supercomputer systems at ISC 2014 in June, the official ranking was announced at the International Conference for High Performance Computing, Networking, Storage, and Analysis (SC14) held in New Orleans, US, in November. proposed a new benchmark program, HPCG, that uses the conjugate gradient method to solve a system of linear equations composed of a sparse coefficient matrix, which are often used in industrial applications. More than 20 years have passed since the project was launched in 1993, and recently it has been pointed out that the performance requirements of actual applications are not met, and the time required for benchmark testing is prolonged.Īccordingly, Dr. The TOP500 has long been a popular benchmark for evaluating computing power, which was an important performance indicator for solving a system of linear equations composed of a dense coefficient matrix. In general, a high LINPACK score is said to be a comprehensive measure of computing power and reliability. LINPACK measures the computing power of double-precision floating-point numbers used in many scientific and industrial applications and to get a high score on this benchmark, it is necessary to run a large-scale benchmark for a long time. Jack Dongarra of the University of Tennessee, US, to solve a system of linear equations by matrix calculation, the LINPACK program was launched in 1993 to announce the supercomputer ranking two times a year (June and November). The TOP500 list is a project that regularly ranks and evaluates the top 500 fastest supercomputer systems in the world based on LINPACK performance. This proves Fugaku's capability to contribute to the advancement of Society 5.0, as a research platform for machine learning and big data analysis. This is also a historical record, as Fugaku achieved 1 exa (10 raised to the power of 18) in one of HPL benchmarks for the first time in the world. For this measurement, a high score of 1.421 EFLOPS (Exa FLOPS) was recorded using 330 racks (126,720 nodes, approximately 79.7% of the entire system) of Fugaku. Unlike the conventional listings of TOP500 and HPCG which measure the performance of double-precision arithmetic logic unit, HPL-AI is a new benchmark established in November 2019 as an index for evaluating calculation performance that takes into account the capabilities of single-precision and half-precision arithmetic logic units used in artificial intelligence. Moreover, Fugaku exceeds the performance of the No.2 supercomputer (2,925.75 TFLOPS) by approximately 4.6 times. This proves that the supercomputer can efficiently handle such real-world applications in the field of industry and perform well. Fugaku's performance is approximately 2.8 times that of the supercomputer ranked second in the TOP500 list with148.6 PFLOPS.įor this benchmark, 360 racks (138,240 nodes, approximately 87% of the entire system) of Fugaku were used to achieve the high score of 13,400 TFLOPS (teraflops). It is the first time for a Japanese supercomputer to take the first place in TOP500 since the K computer claimed No.1 in November 2011 (the 38th TOP 500 list). The Fugaku system ranked first in the TOP500 list consisted of 396 racks (152,064 nodes ( 4), approximately 95.6% of the entire system), and the LINPACK performance was 415.53 PFLOPS (petaflops) with the computing efficiency ratio of 80.87%. Supercomputer Fugaku (in development and preparation) Measurement Results of Fugaku Fugaku can contribute in such society as an information infrastructure technology accelerating the solution of social problems with simulation while advancing the development of AI technologies as well as technologies related to information distribution and processing. 1 in these three rankings indicates the overall high performance of Fugaku and demonstrates that it can sufficiently respond to the needs of Society 5.0 ( 3) which aims to build a smart society that creates new value. These rankings were announced on June 22 at the ongoing virtual event ISC (International Supercomputing Conference) High Performance 2020 Digital. Fugaku also took the No.1 position in the international ranking HPCG (High Performance Conjugate Gradient), which measure the processing speed of the conjugate gradient method ( 2) often used in practical applications including in the field of industry, and in the ranking of HPL-AI, which measures the performance of low-precision computing often used in AI such as deep learning. 1 in the 55th TOP500 list of the world's supercomputers. Fujitsu today announced that Fugaku ( 1), a supercomputer jointly developed by RIKEN and Fujitsu, was ranked No.
