SUMMARY
34th IUPAP Conference on Computational Physics (CCP2023)
CCP2023 was conceived, when Supercomputer Fugaku, which
is housed in RIKEN R-CCS in Kobe, Japan, became No. 1 in theWorld in 4 different categories (Top500, HPCG, HPL-AI, andGraph 500) in 2020.
CCP2023 was held in a complete hybrid way, where all the talks
were accessible by online participants with Zoom webinar. All thetalks were also recorded so that online participants with timedifference could see the videos later. Online poster presentations
were also made possible with Zoom breakout room.
