RIKEN Center for Computational Science System Operations and Development Unit
Unit Leader: Yuji Iguchi
Research Summary
The system operations and development unit has conducted operations and maintenance management, user management, and user support of super computer systems operated by R-CCS in addition to the research and development on advanced management and operations of them. We have made improvements of the job scheduler, file system, and MPI library (communications library) while analyzing the operational statistics of systems.
