In the Group Course, queues are shared among the users of each group. When the amount of computational resources for the job exceeds the minimum amount of allocated cores for the queue, each user ensures resources at a time. Accordingly, it sometimes takes a long time to start to run a job depending on usage status of other users of the whole system.

During a large-scale job is scheduled to run, other jobs may be placed in a pending status depending on the scale of the large-scale job. See the Large-Scale Job Schedule.
