Reasons and benefits of using JAXA Supercomputer System

Because it is a high-capacity storage that can be used by JAXA despite being geographically distant

Achievements of the Year

We have developed tools for implementing backups and efficient management in preparation for regular backup implementation starting from the next fiscal year, and this year we utilized J-SPACE’s storage area for testing purposes.
