Queues (Resource groups/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", "shm", "regular" or "short" as the queue name 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".)
- The upper limit of shared memory (/dev/shm) usage is normally 50% of the physical memory (192 GiB) installed on each compute node, 90% for "shm" queue only.
- New queues, "shm" have been created. (November 22th, 2022)
Pre-post services
For the pre- or post-processing of analytical data such as visualization, it is possible to use nodes of the same configuration as login nodes interactively as interactive jobs.

- Tokens are not consumed.
- * You will be notified of the queue name when you make a reservation.
