Batch Queue, Sometimes also known as job queue (job class) is a system software data structure maintained by job scheduler software.
Users submit their programs that they want executed, "jobs", to the queue for batch processing. The scheduler software maintains the queue as the pool of jobs available for it to run. The queue helps control job traffic, by routing jobs to specific resources and nodes according to the specific workload sets and requests.
Parameters
Multiple batch queues might be used by the scheduler to differentiate types of jobs depending on parameters such as:
- Job priority
- Estimated execution time
- Resource requirements
Purposes
- Routes jobs
- Puts limits on the specific workload sets
Benefits/Features
The use of a batch queue gives these benefits:
- Sharing of computer resources among many users
- Time-shifts job processing to when the computer is less busy
- Avoids idling the compute resources without minute-by-minute human supervision
- Allows around-the-clock high utilization of expensive computing resources
