Masahiro Nakao
Biography
Masahiro Nakao received his Ph.D. from Doshisha University in 2010. He is a technical scientist at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan, and has been working in the field of high-performance computing (HPC) for over a decade.
Since joining RIKEN in December 2013, he has contributed to research and development in areas such as programming environments, system architecture, and operational technologies. As of April 2021, he has been affiliated with the Operations and Computer Technologies Division.
His research interests include HPC systems, parallel and distributed programming models (such as PGAS and OpenACC), operational tools for large-scale computing, and evolutionary computation. He has co-authored papers on graph optimization and PGAS languages, and has presented at international conferences including SC and HPC Asia.
He has also worked on performance tuning of large-scale graph traversal benchmarks, such as Graph500 on the Fugaku supercomputer. These efforts have led to several awards, including multiple first-place rankings in the Graph500 BFS category and the HPCI Software Award in 2025. He has also received recognitions in Graph Golf and the HPC Challenge.
In addition to his research activities, he serves on several program committees (e.g., HPC Asia, XcalableMP Workshops, MCSoC), and has supported community events such as ATMG and the Japanese Supercomputing Contest.
