| 概要 | This project advances computational science by integrating "Simulation/Data/Learning (S+D+L)" using heterogeneous supercomputers like “Wisteria/BDEC-01” and “Miyabi,” along with "mdx." Initially focused on earthquake simulation with real-time data assimilation in FY.2021 and FY.2022, it expanded to other fields from FY.2023, collaborating with international partners. The team developed the h3-Open-BDEC platform to facilitate integration of (S+D+L), gaining global attention. Research spans earth and life sciences, and software development. In FY.2025, the project will include quantum sciences and extend h3-Open-BDEC for QC-HPC Hybrid Environment. |
