RIKEN Center for Computational Science Operations and Computer Technologies Division

Director: Fumiyoshi Shoji (Ph.D.)

Research Summary

Fumiyoshi  Shoji(Ph.D.)

Operations and Computer Technologies Division is engaged in research and development of advanced usage technologies and advanced operation technologies of the K computer in conjunction with large facilities such as refrigerators and air handling units, as well as daily operation and management of the K computer, the building facilities and network facilities required for stable operation of the K computer system, which has top class capability in the world, as a common use facility around Japan. It also develops outstanding infrastructure of application development that will take full advantage of the capabilities of the K computer.
