[M-GI30] Computational sciences on the universe, galaxies, stars, planets and their environments

Tue. May 27, 2025 5:15 PM - 7:15 PM Poster Hall (Exhibition Hall 7&8, Makuhari Messe)

convener:Wataru Ohfuchi(Kobe University), Junichiro Makino(Kobe University), Masanori Kameyama(Geodynamics Research Center, Ehime University), Hideyuki Hotta(Nagoya University)

Computer simulations have played critical roles in elucidating and understanding the planetary formation and evolution, planetary surface environments and their diversity, the solar and stellar dynamics, and the structure formation and evolution of the universe. While computer performance has increased by seven orders of magnitude over the past 30 years, this has not necessarily improved simulation outcomes. In this session, we aim to explore how to exploit these improvements in computing performance to the quantitative and qualitative advancement of space, planet, and earth sciences with the current "Fugaku" and the coming post "Fugaku" computers. We invite presentations from theoretical, observational, numerical simulation and AI studies and will hold a session for comprehensive discussions on the future direction of the fields. We welcome cross-disciplinary participation from all fields of the Japan Geoscience Union, not limited to space, planet, and earth science.
