Introduction to courses (FY2023~)

Wisteria/BDEC-01 »  Click here for "Queues (Resource groups/Job classes)"

General use course

This 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 Wisteria/BDEC-01 system is 2TB per set. In addition to that, each user belonging to the group is allocated 50GB of disk storage.
While there are no limit to the number of users who can be registered, 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 and GPU Number of tokens allocated (per year) and consumption coefficient Disk storage
General use course
(Per set)
90,000 yen Wisteria-O :
Maximum of 2304 nodes

Wisteria-A :
Maximum of 64 GPU
8,640 tokens
(1 node, Equivalent to 24 hours x 360 days)
Wisteria-O consumption coefficient : 1.00
(per node)
*Priority nodes (about 15% of the total) will have a consumption factor of 1.50.
Wisteria-A consumption coefficient : 3.00
(per GPU)
  • Group (/work):
    2TB
  • User (/home): 50GB
  • Regardless of the number of sets applied for, jobs can be executed up to the number of nodes・GPU usable.
  • Depending on the application status, the number of sets applied for may be adjusted.
  • Disk storage for /home for users does not increase even if the user is a user of multiple group courses.
  • Disk storage for /home for users is fixed regardless of the number of sets applied for.

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).

  • Disk storage for /home for users does not increase even if the user is a user of multiple group courses.
  • Disk storage for /home for users is fixed regardless of the number of sets applied for.

Reserved GPU

Reserved GPU course allows exclusive use of the same number of GPUs as the number of application sets (1 or 2 or 4). However, one node is shared by multiple application groups. Since the GPU used within a node is not fixed, the GPU used may differ for each job run. There is no screening at the application (and continuation of use per year).
