In [[system software]], a '''job queue''' ({{aka}} '''batch queue''', '''input queue'''), is a data structure maintained by [[job scheduler]] software containing jobs to run.<ref>{{Cite web |date=2018-08-14 |title=Job queues |url=https://www.ibm.com/docs/en/i/7.1?topic=concepts-job-queues |access-date=2022-03-19 |website=www.ibm.com |language=en-us}}</ref><br />
<br />
Users submit their programs that they want executed, "jobs", to the queue for [[batch processing]]. <br />
The scheduler software maintains the queue as the pool of jobs available for it to run. <br />
<br />
Multiple batch queues might be used by the scheduler to differentiate types of jobs <br />
depending on parameters such as:<br />
* job priority<br />
* estimated [[Run time (program lifecycle phase)|execution time]]<br />
* resource requirements <br />
<br />
The use of a batch queue gives these benefits:<br />
* sharing of computer resources among many users<br />
* time-shifts job processing to when the computer is less busy<br />
* avoids idling the compute resources without minute-by-minute human supervision<br />
* allows around-the-clock high utilization of expensive computing resources<br />
<br />
Any process that comes to the CPU should wait in a queue.<br />
