On Oakbridge-CX supercomputer system,Tokens, which is the number of hours that compute nodes can be used for, are assigned corresponding to the course of use and number of nodes applied for. Batch jobs can be executed up to the maximum number of nodes that can be used, and within the number of tokens assigned (with the exception of some courses and services).

Please read the following points to be noted when using the tokens. For a detailed explanation and FAQs about tokens, please refer to the page "Tokens".

Tokens are consumed for the execution of each batch job (with the exception of batch jobs that make use of interactive nodes).
Tokens are consumed for the amount of time calculated through node-hour product “Time lapsed × Number of nodes × Consumption coefficient.”
For jobs in excess of the number of nodes applied for, a higher consumption coefficient is set for the number of nodes in excess.
Tokens may be added only when there is a surplus in the calculation resources.
There is no guarantee that all tokens can be used up within the effective period when use of the tokens is permitted. Furthermore, as the tokens are only valid within the period that use is permitted for, even if there are any remaining tokens, they may not be transferred to the next fiscal year, nor will any refunds be provided.

Regular use (General)

The General course is designed for use by research groups, etc., and application for use can be submitted for in units of set (as the amount of resources available is limited, there are cases where the unit of use applied for cannot be provided). The standard disk storage allocated for the Oabridge-CX system is 4TB per set. In addition to that, each user belonging to the group is allocated 50GB of disk storage.
While there are no restrictions on the number of users who can be registered in a group, please note that the tokens allocated are shared among the registered users. For that reason, we have introduced a system that allows the group administrator, who is designated during the application for use, to make changes to the number of tokens assigned to each user within the group.

	Cost of use (Per year, including tax)	Number of usable nodes	Number of tokens allocated (per year) and consumption coefficient	Disk storage
General use course (Per set)	150,000 yen	Maximum of 256 nodes	8,640 tokens Consumption coefficient:1.00 *Priority nodes (about 15% of the total) will have a consumption factor of 1.50.	Group (/work): 4TB User (/home): 50GB

※ Regardless of the number of nodes applied for, jobs can be executed up to the maximum number of nodes usable (256).
※ Disk storage for /home for users is fixed regardless of the number of nodes applied for.
※ This table is for those affilated with Universities, public organizations, etc.

Fixed nodes

The fixed node course allows users to monopolize the use of nodes. Apart from using the nodes for batch jobs, they can also be used for commercial programs, special libraries, and the customization of the usage environment (interactive execution environment, use of local disks, etc.). However, applications (and continuation of use per year) will be screened.

Please see here for details on group course (fixed node).

	Cost of use (Per year, including tax)	Number of usable nodes	Number of tokens allocated (per year) and consumption coefficient	Disk storage
Fixed nodes (Per set)	225,000 yen	Maximum of 256 nodes	8,640 tokens Consumption coefficient:1.00 *Priority nodes (about 15% of the total) will have a consumption factor of 1.50.	Group (/work): 4TB User (/home): 50GB

Additional tokens, additional disk storage

	Cost of use (Per year, including tax)	Remarks
Addition of tokens	12,500 yen (720 tokens)
Addition of disk storage	6,480 yen (1TB)	Application by units of 1TB is accepted
