The Evolution of Japanese Supercomputers
The history of Japanese supercomputers traces back to the late 20th century, with the country making its mark early on through significant technological innovations. Japan’s supercomputing journey began with the development of the Fugaku supercomputer, which earned global recognition as the fastest supercomputer in the world.
Fugaku, developed by RIKEN and Fujitsu, was officially ranked as the world’s fastest supercomputer in 2020, a position it held for several years. Its groundbreaking performance was achieved with over 7.6 million cores, making it capable of performing over 442 petaflops (quadrillion floating-point operations per second). Fugaku’s peak performance, measured in exaflops (one quintillion operations per second), heralded a new era for high-performance computing.
But Fugaku is only one example in a long line of significant Japanese supercomputers. Prior to Fugaku, K computer was another remarkable achievement, which claimed the top spot in the TOP500 ranking in 2011. Developed by RIKEN and Fujitsu, the K computer had a performance of 10 petaflops, which was a massive leap forward for supercomputing at the time.
Japan’s commitment to supercomputing continues with investments in next-generation systems that push the limits of computational speed, efficiency, and energy use. This ongoing development is driven by the government, academic institutions, and private sector collaboration, all working together to ensure that Japan remains at the cutting edge of technological advancements.
