[SY-K1] Supercomputer Post-K Project “Challenge of Basic Science - Exploring Extremes through Multi-Physics and Multi-Scale Simulations”
Japanese government plans to construct a supercomputer Post-K at 2021, which is expected to have over 1018 flops. This calculation speed is 100 times faster than the present supercomputer K in Kobe, Japan. Japanese government started 13 projects (9 priority issues and 4 exploratory challenges) to develop original simulators for the supercomputer Post-K. Our Post-K project “Challenge of Basic Science - Exploring Extremes through Multi-Physics and Multi-Scale Simulations” (Leader: Prof. Momoji Kubo, Institute for Materials Research, Tohoku University) was selected as one of four exploratory challenges at June, 2016 and started at August, 2016. The summary of our Post-K project is as follows.
Supercomputer K significantly advanced individual sciences on exploring extremes such as fracture of materials, earthquake, atmospheric flow, ocean flow, volcanic eruption, magma, and extreme properties. On the basis of the above individual understanding obtained by supercomputer K, our Post-K project aims to solve multi-physics and multi-scale problems for exploring extremes by developing new calculation methods beyond the limits of calculation accuracy and possibility and by bridging the different physics and scales. Our Post-K project consists of four sub-challenges.
Sub-Challenge A: Fracture and Catastrophe
(Sub-Leader: Prof. Momoji Kubo, Tohoku University)
Sub-Challenge B: Phase Transitions and Flows
(Sub-Leader: Prof. Toshihiro Kawakatsu, Tohoku University)
Sub-Challenge C: Structures and Properties of Materials in Deep Earth and Planets
(Sub-Leader: Dr. Toshiaki Iitaka, RIKEN)
Sub-Challenge D: Fundamental Quantum Mechanics and Informatics
(Sub-Leader: Prof. Naoki Kawashima, The University of Tokyo)
In the supercomputer Post-K project, our group is focusing on the fracture and catastrophe of materials. Our recent outcomes on the following three topics will be presented in the conference.
Friction and wear processes of diamond-like carbon thin films.Stacking fault generation processes of polycrystalline ceramics.Sintering processes of Ni/YSZ electrode in solid oxide fuel cell.
