Smart IoT Sensing for Ageing Well: Research Activities and Future Directions

Michael Sheng, Macquarie University

Worldwide, the population is aging due to increasing life expectancy and decreasing fertility. The significant growth in older population presents many challenges to health and aged care services. Over the past two decades, the Internet of Things (IoT) has gained significant momentum and is widely regarded as an important technology to change the world in the coming decade. Indeed, IoT will play a critical role to improve productivity, operational effectiveness, decision making, and to identify new business service models for social and economic opportunities. Indeed, with the development of low-cost, unobtrusive IoT sensors, along with data analytics and artificial intelligence (AI) technologies, there is now a significant opportunity to improve the wellbeing and quality of life particularly of our older population. In this presentation, we will overview some related research projects and also discuss several research directions.


Algorithms and Systems Enabling AI for Science

Geoffrey Fox, University of Virginia

Currently, AI and in particular deep learning plays a major role in science, from data analytics and simulation surrogates to policy and systemdecisions. This role is likely to increase as ideas from early adopters spread across academic fields. We can group the structure of "AI for Science" into a “handful” (≤10) of patterns and we need to explore examples of each pattern, possibly leading to “Foundation” models for each of them. We suggest examining each pattern and supporting it with high-performance, easy-to-use environments for end-to-end systems, including data engineering. This would cover parallelism, storage and data movement, security, and the user interface. We illustrate this with the Cylon system which is HPC Software for Data Engineering.


Toward Next-Generation Supercomputer Systems: Vision and Activities in Japanese HPC Community

Masaaki Kondo, Keio University

The supercomputer Fugaku began its operations in 2021 and has successfully produced many useful scientific and engineering results. The use of a high-performance computing systems such as Fugaku is essential as a digital twin platform that reproduces physical space on cyberspace for the realization of future smart society. There is a growing demand for the development of next-generation supercomputer systems with higher performance supporting wider range of applications. However, there are many technical challenges towards development of next generation systems as we are now facing the end of Moore's law. Hence we launched a community activity for Next-Generation Advanced Computing Infrastructure (NGACI) in 2019 to discuss the roadmap of future HPC platforms, technical challenges, and necessary R&D elements. We have also started a feasibility studies on next-generation supercomputing infrastructures this year as a part of a national project by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) Japan. This talk introduces these activities and reviews recent trends in the development of supercomputing systems beyond exascale.


Digital Convergence

Michael Resch, High Performance Computing Center Stuttgart

The world of High Performance Computing is undergoing major changes. The coming end of Moore’s law has triggered attempts to push the limits of hardware which has resulted in an increasing usage of accelerator technologies. With these new systems a new user community has arisen. Artificial Intelligence has seen a spectacular comeback over the last years. While Artificial Intelligence and High Performance Computing seem to be rather different in their requirements and targets we see the evolution of what we want to call Digital Convergence. Users increasingly rely on both HPC and AI to solve their problems. This is further supported by a tremendous increase in data available for research. This talk will discuss the options and challenges that the new Digital Convergence creates.
