Research group of Assoc. Prof. Tsuyoshi Ichimura and Ph.D student Takuma Yamaguchi was awarded the following prizes in SC17 at Denver, USA. SC17 is one of the top conferences in high-performance computing.
■Research by Assoc. Prof. Tsuyoshi Ichimura, Assis. Prof. Kohei Fujita, Ph.D student Takuma Yamaguchi, Prof. Muneo Hori, Assoc. Prof. Lalith Maddegedara, and Vice Director Naonori Ueda (RIKEN Center for Advanced Intelligence Project) was awarded the SC17 Best Poster Award. Research posters in SC conference series are known for its high level exploratory research. This year, 99 out of 169 submissions were accepted (acceptance rate 58%), and one best poster was selected out of the accepted submissions.
Research summary:
The research subject to the award is concerning next generation earthquake ground motion estimation system based on large-scale simulation combined with artificial intelligence (AI). Here, an AI trained with earthquake ground motion data computed using the full K computer system enabled fast estimation of ground motion for wide areas concerning uncertainty.

■Research by Ph.D student Takuma Yamaguchi, Assis. Prof. Kohei Fujita, Assoc. Prof. Tsuyoshi Ichimura, Prof. Muneo Hori, Assoc. Prof. Lalith Maddegedara, and Prof. Kengo Nakajima (Information Technology Center) was awarded Best Paper Award in Fourth Workshop on Accelerator Programming Using Directives (WACCPD) held in conjunction with SC17.
Research summary:
The research subject to the award is concerning acceleration of large-scale, many-case high-resolution finite-element simulation for three-dimensional crust-deformation analyses using GPUs. This research is expected to be useful for improving quantitative analysis of crust-deformation by many-case, large-scale analysis.
