Research Summary

Hiroya  Matsuba(Ph.D.)

Our mission is to improve programming productivity for supercomputers. Raising supercomputer-programming efficiency is important because of the growing need to rapidly simulate various real-world events and phenomena. Going forward, rapid simulation will become even more necessary, as it is expected to be an essential tool for artificial intelligence, given simulations provide virtual environments in which AI can learn. Additionally, simulation aids more practical data analysis because it can generate data of rare events.

We are researching programming techniques to combine existing tools and frameworks for simulation, data analysis, and machine learning, as well as preparing such tools for use on supercomputer Fugaku. We are also developing a new programming environment that employs highly abstract descriptions to make use of these tools and frameworks. This will enable users to conduct simulations, data analysis, and their combinations with less development effort than is required today. We are also collaborating with industry. Considering the fact that the industrial trend is shifting from making products to providing services, we believe academic institutions should provide our research results to users as a service. In order to promote this goal, we are investigating not only the most efficient programming techniques, but also what will produce the most practical benefits for users.
