Research summary
Utilizing the data processing capabilities of the Fugaku supercomputer, the Data Integration Unit engages in research, development, and operation of advanced utilization infrastructure in conjunction with various computing resources, data resources, and observation equipment. At the same time, we will build and operate research management infrastructure, prepost processing including visualization, and workflow processing.
We also will be enhancing the HPCI shared storage system.
