Job classes

Interactive job services

Apart from login nodes, interactive nodes (environment), which have the same architecture as compute nodes, are also available. Interactive nodes allow for the execution of programs interactively through the executive of interactive jobs, so please use these nodes for debugging programs and other relevant purposes.

Batch job services

When occupying nodes for a fixed period of time to carry out batch processing, the job is executed as a batch job. (As it is not compatible with the job execution script used in the Oakforest-PACS, Reedbush systems, etc., it is necessary to create a new script.)

  • It is possible to submit jobs to your preferred queue as long as you have a sufficient number of tokens. However, the maximum number of nodes that can be used is 2,048.
  • It is necessary to assign either "debug", "regular" or "short" as the queue name (job class) when submitting a job. When assigning either "regular" queues for either of the internal names will be submitted in accordance with the number of nodes. (It is not possible to submit jobs by assigning individual internal names such as "small" or "medium".)
