RIKEN Center for Computational Science Advanced Operation Technologies Unit
Unit Leader: Keiji Yamamoto (Ph.D.)
Research Summary
Advanced Operation Technologies Unit is engaged in research and development for advanced operation of the entire data center, including Supercomputer Fugaku and infrastructure such as power supplies, cooling facilities, and networks. In particular, we will develop a platform system for analyzing enormous operational data, which is also big data, improve operations based on knowledge obtained by the data analysis, research the new use of supercomputers such as virtualization and cloud computing. We will also collaborate with domestic and international HPC research institutions to research future supercomputers and data centers.
