Outline of Research at the Start

エクサスケール時代のスパコンによる科学的発見の持続的促進のために,計算科学にデータ科学,機械学習の知見を導入した(計算+データ+学習)融合による革新的シミュレーション手法を提案する。最小の計算時間・消費電力での融合の実現のために,①変動精度演算・精度保証・自動チューニングによる新計算原理に基づく高性能・高信頼性・省電力数値解法,②機械学習による階層型データ駆動アプローチの二項目を中心に研究し,革新的ソフトウェア基盤「h3-Open-BDEC」として整備する。(計算+データ+学習)融合による多階層シミュレーションにおいて,従来手法と同等の正確さを保ちつつ10倍以上の計算量・消費電力削減を目指す。

Outline of Final Research Achievements

In order to fully utilize the capabilities of supercomputers in the Exascale era and continuously promote scientific discoveries, we proposed an innovative simulation approach that integrates "Simulation/Data/Learning (S+D+L)". We conducted research and development to achieve integrated simulations with minimal computational requirements and power consumption, and implemented the innovative software framework "h3-Open-BDEC" to realize this. Since FY. 2021, using the Wisteria/BDEC-01 system at the University of Tokyo, we have been promoting the integration of “S+D+L” in various fields. Finally, We were able to conduct simulations with around 100 times the efficiency of conventional methods while maintaining accuracy in simulations of steady-state flow around vehicle bodies and global atmospheric ensembles. Our achievements have been highly evaluated internationally.

Academic Significance and Societal Importance of the Research Achievements

スーパーコンピュータ(スパコン)は従来のシミュレーションの他,データ解析,機械学習・AI等様々な分野で使用されている。本研究では,「計算(シミュレーション)・データ・学習」融合による,新しい計算科学の開拓と,それにより安心・安全な人間中心の社会(Society 5.0)の構築を実現するためのソフトウェア開発を実施した。「計算・データ・学習」融合により,車体周囲定常流,全球大気アンサンブルシミュレーションが従来の100分の1の計算時間で実施可能となり,スパコンの新しい利用方法を開拓した。本研究の成果は量子コンピュータとスパコンの連携にも転用可能であり,量子コンピューティング普及に貢献する。
