概要 |
In this project, we advance computational science by integrating "Simulation/Data/Learning (S+D+L)” using heterogeneous supercomputers like “Wisteria/BDEC-01 (U.Tokyo)” and “Flow (Nagoya U.)”, along with "mdx." In FY.2021 and FY.2022, our focus was earthquake simulation with real-time data assimilation. From FY.2023, we expand the "S+D+L" concept to other fields, initiating joint research and software development with international partners (Germany: JSC, FAU, France: CEA, Croatia: RBI). The project's leading PI and colleagues have been working on the innovative software platform “h3-Open-BDEC (https://h3-open-bdec.cc.u-tokyo.ac.jp/)” [3,4,5] since FY.2019 to facilitate "S+D+L" integration on heterogeneous systems like Wisteria/BDEC-01. Currently, Wisteria/BDEC-01 (“Odyssey” for Simulations with A64FX, “Aquarius” for Data/ML/AI with NVIDIA A100) operates as a full-scale platform for "S+D+L" integration with h3-Open-BDEC, gaining global attention. In FY.2023, we conducted research in atmospheric simulations, ported international partner applications to Wisteria/BDEC-01, and investigated "S+D+L" integration using h3-Open-BDEC. For FY.2024, we switch to the international project and focus on the fields of earth science, life science, and library/software/tool for integration of "S+D+L". JSC (Jülich Supercomputing Centre, Germany), one of the international partners of this project, also conducts research on heterogeneous computing based on the idea of Modular Supercomputing Architecture. Some of the target applications in this project by JSC, such as TSMP and ChASE, are already feasible in heterogeneous environments. |
