Invited Talk 4: Innovative Supercomputing by Integrations of Simulations/Data/Learning on Oakforest-PACS II
DescriptionRecently, supercomputing has been changing dramatically. Integration/convergence of Simulation/Data/Learning (S+D+L) is important towards Society 5.0 proposed by Japanese Government, which enables integration of cyber space and physical space. In 2015, we started the BDEC project (Big Data & Extreme Computing) for development of supercomputers and software for integration of (S+D+L). In May 2021, we started operation of the Wisteria/BDEC-01. It is the first BDEC system, which consists of computing nodes for computational science and engineering with A64FX (Odyssey), and those for Data Analytics/AI with NVIDIA A100 GPU’s (Aquarius). We also develop a software platform “h3-Open-BDEC” for integration of (S+D+L) on the Wisteria/BDEC-01, which is designed for extracting the maximum performance of the supercomputers with minimum energy consumption focusing on (1) Innovative method for numerical analysis by adaptive precision, accuracy verification and automatic tuning, (2) Hierarchical Data Driven Approach based on machine learning, and (3) Software for heterogeneous systems. Integration of (S+D+L) by h3-Open-BDEC enables significant reduction of computations and power consumption, compared to those by conventional simulations. In January 2025, we will start to operate the Oakforest-PACS II system (OFP-II) together with University of Tsukuba. OFP-II will consist of NVIDIA H100 nodes with a total peak performance of 100+ PFLOPS. This is our next platform for integration of (S+D+L). Since October 2022, we started supports for our users to migrate their applications to the OFP-II with GPUs under collaboration with NVIDIA. In this talk, our activities in integration of (S+D+L) and efforts towards OFP-II will be described.
