RIKEN Center for Computational Science HPC Usability Development Unit

Unit Leader: Fumiyoshi Shoji (Ph.D.)

Research Summary

Fumiyoshi  Shoji(Ph.D.)

HPC Usability Development Team enhances user environments of the supercomputer Fugaku. In order to improve and enhance the usability of Fugaku, we analyze huge operation data from Fugaku and develop the method to provide better user environment. We also enhance the HPCI shared storage system.

  • Development and enhancement of the usability of Fugaku
  • Development and enhancement of the HPCI shared storage system
