SUMMARY:Invited Talk 4:  Innovative Supercomputing by Integrations of Simu
 lations/Data/Learning on Oakforest-PACS II
DESCRIPTION:Kengo Nakajima (University of Tokyo)\n\nRecently, supercomputi
 ng has been changing dramatically. Integration/convergence of Simulation/D
 ata/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 de
 velopment of supercomputers and software for integration of (S+D+L). In Ma
 y 2021, we started operation of the Wisteria/BDEC-01. It is the first BDEC
  system, which consists of computing nodes for computational science and e
 ngineering with A64FX (Odyssey), and those for Data Analytics/AI with NVID
 IA A100 GPU’s (Aquarius). We also develop a software platform “h3-Open-BDE
 C” for integration of (S+D+L) on the Wisteria/BDEC-01, which is designed f
 or extracting the maximum performance of the supercomputers with minimum e
 nergy consumption focusing on (1) Innovative method for numerical analysis
  by adaptive precision, accuracy verification and automatic tuning, (2) Hi
 erarchical Data Driven Approach based on machine learning, and (3) Softwar
 e for heterogeneous systems. Integration of (S+D+L) by h3-Open-BDEC enable
 s significant reduction of computations and power consumption, compared to
  those by conventional simulations. In January 2025, we will start to oper
 ate the Oakforest-PACS II system (OFP-II) together with University of Tsuk
 uba. OFP-II will consist of NVIDIA H100 nodes with a total peak performanc
 e of 100+ PFLOPS. This is our next platform for integration of (S+D+L). Si
 nce October 2022, we started supports for our users to migrate their appli
 cations to the OFP-II with GPUs under collaboration with NVIDIA. In this t
 alk, our activities in integration of (S+D+L) and efforts towards OFP-II w
 ill be described.\n\nTag: Algorithms, Heterogeneous Computing, Large Scale
