Research summary
We are developing the next-generation HPC infrastructure “FugakuNEXT” by advancing the construction of high-efficiency data center facilities and conducting research and development on sustainable, advanced operation technologies that leverage them. By optimizing the facilities and supercomputers as an integrated system, we aim to establish a highly reliable and user-friendly operational platform for both users and administrators.
