TOP Research Future Developments Feasibility Studies on Next-Generation Supercomputing Infrastructures (Aug 2022- )
The next-generation computational infrastructure is expected to become a platform for realizing SDGs and Society 5.0 by providing advanced digital twins that will bring "Research DX" in the science. Aiming to realize a versatile computing infrastructure that can execute entire workflow by making full use of wide range of computational methods, simulation techniques, and BigData at scale, we conduct a holistic investigation on architecture, system software and library technologies through co-design with applications.
As a basic principle of system design, we practice the "FLOPS to Byte" concept from architecture development to algorithm or application design to streamline data transfer and computation under power constraints, while taking necessary computing accuracy into consideration. Under the ALL JAPAN team composition, we will investigate system configurations and elementary technologies which improve effective performance of the next-generation computing infrastructure.
Subject of Investigation
Research on Architecture
- Investigating technological possibilities (such as 3D stacked mem, accelerators, chip-to-chip direct optical link) and performance of the entire system or its components based on trends in semiconductor and packaging technologies
- Predicting future system performance based on performance analysis of benchmark sets provided by Application Research Group, and feeding back to next-generation application development
Research on System Software and Library
- Drawing roadmap for future system software development in Japan, specially considering data utilization enhancement, integration of AI technology with first-principles simulation, real-time data processing, and assurance of high security
Research on Applications
- Building a broad benchmark set to evaluate multiple architecture choices while considering improvements in algorithms and parameters of application based on the results of architectural evaluations and exploratory "what-if" performance analysis
- Investigating what classes of algorithms are expected to evolve significantly for future systems
