Title: Major issues in exascale computing in China
Starting with a brief historical review on high performance computing in China, this talk presents the major technical issues in developing the exascale computers, including architectures, processor, memory, interconnect, reliability, and low power design, etc. Issues about system software and application ecosystem are also raised. Then the status of China’s national key project on exascale computing is presented. Perspectives and some open issues are introduced towards the end of this talk.

Title: Transforming SMEs and Manufacturing industry business into AI ready empowered by the ABCI
Artificial intelligence (AI) is already leading the world’s industrial revolution, interacting with IoT, big data, robots, cloud technology, and more. While business owners scream, they say, “AI’s! Open innovation!” But there may be a sense of frustration that is left while we are wondering where to start introducing AI for their business. It is hard to say that what can be realized and connected to the market, possibilities, and limitations, research and development and how to apply development, etc. are still well understood in the SMEs and manufacturing industry in particular in Japan. Considering such business surroundings, AIST initiated a project to offer the computing power for everybody to receive its benefit so that they can try to use AI technologies. We have been operating the ABCI, Artificial Intelligence Bridging Cloud Infrastructure, since August in 2019. From our practice, I would like to share the ideas on how to utilize such supercomputer systems for transforming their business.

Title: Performance engineering for sparse matrix, tensor, and graph computations
At the heart of many computational problems in scientific computing and data analysis lie sparse matrix, tensor, and graph computations. This talk summarizes a few of our recent results in the design of communication-avoiding algorithms, data structures, and controller-based dynamic tuning and control software for such computations. Specific examples will include the sparse direct solvers, tensor decompositions, and the calculation of shortest paths in graph analysis. Collectively, this work sheds light on fundamental issues of how to mitigate the high cost of communication, increasing need to improve locality, and operate efficiently in heterogeneous power-constrained environments.
