This is the first time that a Japanese supercomputer has bagged the top position since June 2011, when the “K computer” – Fugaku’s predecessor – took first place. Jointly developed by Japan’s state-backed RIKEN Center for Computational Science and the firm Fujitsu, Fugaku is the first-ever ARM-based system to become the world’s fastest supercomputer. It scored a High-Performance Linpack (HPL) score of 415.5 petaflops, which makes it 2.8 times faster than IBM Summit’s 148.6 petaflops that is now in second place in the Top500 supercomputer rankings. Fugaku is powered by Fujitsu’s 48-core Arm-based A64FX system-on-chip and consists of nearly 7.3-million CPU cores. In single-precision operations, it reaches peak performance of over 1,000 petaflops (1 exaflops). The chips run at 2.0 GHz with a boost to 2.2 GHz and carry 32 GB of HBM2 memory each. This ARM-based supercomputer also secured the number one position in other rankings that test computers on different parameters, including Graph 500, HPL-AI, and HPCG (High-Performance Conjugate Gradient). This is the first time that a supercomputer has simultaneously topped the rankings in the above four categories, according to Fujitsu. “I feel extremely happy and honored to have been involved in creating Fugaku, which has ranked as the world’s No.1 (supercomputer),” said Shinichi Kato, President of Fujitsu IT Products Ltd.

In recent years, countries like the U.S. and China have dominated the race to develop powerful machines. This time too China dominated the TOP500 list with 226 supercomputers, while the U.S. took second place with 114 systems, followed by Japan with 30, France with 18, and Germany with 16 systems.
