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 K computer.
In order to improve and enhance the usability of the K computer, we analyze huge operation data from K and develop the method to provide better user environment.
We also enhance the HPCI shared storage system.
