Group course (fixed nodes)


This course is able to meet needs that are difficult to handle when using the general group course. The following needs, for example, can be met using this course.

  • I wish to use the commercial programs that require license servers.
  • I wish to use dedicated HD to ensure data security.
  • I wish to lay down dedicated communication lines for data transmission.
  • I wish to have proprietary nodes to focus on calculations.
  • I wish to execute jobs that take a long time, and which cannot be handled using general batch job queues.


Please download the application forms here.

Points to note

  • The calculation resources that are contributed to the group course (fixed nodes) are limited to about 10% of the total resources.
  • A review will be carried out after application.
  • Please refer to the guidelines of the application form for other details.

Example of use: Application for 16 nodes

  • Number of tokens: 16 nodes x 360 days = 138,240 node-hours
  • Use of batch job queues allocated for dedicated use
    • The total maximum number of nodes that can be used simultaneously within the group is 16.
    • For example, it is also possible to execute two 8-node jobs at the same time.
    • The number of tokens for the number of node-hours used is consumed.
  • When 16 nodes are already in use for the dedicated batch job queues
    • When the same queues are assigned, you will have to wait until the required nodes are free.
    • If you wish to execute calculations at the same time, it is also possible to execute calculations using general batch job queues.
      • Tokens are consumed based on the number of node-hours used, and the number of tokens that can be used for the number of fixed nodes decreases accordingly.
  • If you wish to carry out calculations for more than 16 nodes
    • Execution using general batch job queues is possible.
      For example, if you wish to execute 128 nodes of calculations for four hours
      • Assign the general batch job queue (“regular”) and execute.
      • Number of tokens consumed: 16 nodes x 4 hours x Coefficient of 1.0 + 112 nodes x 4 hours x Coefficient of 2.0 = 960 node-hours
