Charging Rules of TSUBAME4.0 Supercomputer, Institute of Science Tokyo
October 1, 2024
Article 1 (Purpose)
These rules prescribe the matters necessary for charging usage fees and related matters for the TSUBAME4.0 supercomputer (hereinafter referred to as “TSUBAME4.0”) managed by the Center for Information Infrastructure, Institute of Science Tokyo, pursuant to Article 13, paragraph 3 of the Detailed Terms of Use for Computer Systems (hereinafter referred to as the “Detailed Rules”).
Article 2 (Charging of Usage Fees)
1. Usage fees for TSUBAME4.0 shall be charged at the time of purchase of TSUBAME4 points (hereinafter referred to as “points”) used for the use of TSUBAME4.0.
2. The price of points shall be as specified in Appended Table 1.
3. Points may be purchased on a group basis. In such cases, when the group includes users with different eligibility categories, the highest unit price category applicable within the group shall be applied.
Article 3 (Use of Points)
Points shall be used for computation nodes, group storage, and applications specified in Appended Tables 6 and 7.
Article 4 (Points for Use of Computation Nodes)
1. Points to be used for computation nodes shall be calculated according to the formulas specified for each category in Appended Table 2. Any fraction less than 1/10,000 of a point shall be rounded down.
2. Coefficients used in the calculation formulas shall be as specified in Appended Tables 3, 4, and 5 according to resource type, priority, and reservation timing, respectively.
Article 5 (Points for Use of Group Storage)
1. Points for group storage consisting of hard disk drives shall be 0.5 points per TB per month. The number of files (i-nodes) that can be stored shall be 2,000,000 per TB.
2. Points for group storage consisting of SSDs shall be 0.2 points per 100 GB per month. The number of files (i-nodes) that can be stored shall be 200,000 per 100 GB.
Article 6 (Points for Use of Applications)
1. Points for the use of applications specified in Appended Table 6 on TSUBAME4.0 (per user per month) shall be as specified in that table.
2. Points for the use of applications specified in Appended Table 7 using TSUBAME4.0 licenses on computers in laboratories on campus (per laboratory per fiscal year) shall be as specified in that table.
Article 7 (Validity Period of Points)
Points shall be valid only during the fiscal year in which they are purchased.
Supplementary Provisions
These rules shall come into force on December 20, 2024, and shall apply retroactively from October 1, 2024.
Supplementary Provision (Partially revised on March 7, 2025)

Appended Table 2 (related to Article 4)
| Category | Formula |
|---|---|
| Pay-as-you-go | Points per job = (Number of nodes × Resource type coefficient × Priority coefficient × (0.7 × max(actual runtime (sec), 300) + 0.1 × requested runtime (sec))) ÷ 3,600 |
| Interactive Job Queue | Points per job = (Number of nodes × 0.100 × actual runtime (sec)) ÷ 3,600 However, users defined in Article 4, Paragraph 1, Items (1) and (2) are exempt from charges. |
| Node Reservation | Points per reservation = Number of nodes × Reservation timing coefficient × Resource type coefficient × Reserved time (hours) |
| Flat-rate | Monthly points = Number of nodes × 10.0 × 30 × 24 |
