HPC System "KAGAYAKI" will be replaced with a new system at the end of next February, as the other computing facilities had been done so. Since the replacement will include related facility work such as updating the cooling system, the current KAGAYAKI is expected to be taken out of service at an early date. 
We will update this page as soon as the details are finalized, so please check back regularly.

In addition, please carefully consider your schedule when using the KAGAYAKI for papers, research conferences, etc.
If you are using the KAGAYAKI jointly with researchers outside the university, please share this information with your joint research partners as necessary.

*The following is a guideline as of August 2025.
