The supercomputer Fugaku, which has been in development since 2014, will be made available for shared use starting on March 9. Fugaku, which swept the international high-performance computing rankings in both June and November 2020, taking top place in the Top500, HPCG, HPL-AI, and Graph 500 benchmarks, was developed to contribute to the solution of important scientific and social issues in areas including drug discovery; personalized and preventive medicine; simulations of natural disasters; weather and climate forecasting; energy creation, storage, and use; development of clean energy; new material development; new design and production processes; and; elucidation of the fundamental laws and evolution of the universe. It is currently being used, among other tasks, for projects related to COVID-19 research. In line with the aim to make it very user-friendly system, it is the first supercomputer built on ARM chips, which are widely used in mobile and other consumer devices. Screening of shared-use projects will be managed by the Research Organization for Information Science and Technology, which manages usage of Japan’s high-performance computing infrastructure, including Fugaku.
