RIKEN Center for Computational Science Operations and Computer Technologies Division
Director: Fumiyoshi Shoji (Ph.D.)
Research Summary
Operations and Computer Technologies Division operates the supercomputer Fugaku and its facilities for electricity and cooling as well as network infrastructure of R-CCS. We also are engaged in research and development of technologies for stable and efficient operations of Fugaku and its facilities and enhancement of the usability of Fugaku. Our mission also includes assisting the activity to construct software eco-system for the arm architecture, including Fugaku.
