The Queue is a professional service for author s, literary agent s and publisher s, utilized in the book publishing industry. Authors without agents or who are not interested in self publishing send their raw manuscript s to The Queue for a critique and consultation in lieu of soliciting directly to publishers. Polished manuscripts ready for publication are placed in the On Queue section of the Web site s forum and are made available for and marketed to agents and publishers. As manuscripts are published, they are taken off the queue. If a manuscript reaches the top of the queue and has not yet been picked up by any other publishing company, The Queue will publish the manuscript as a separate imprint of parent company, Scarletta Press .

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. Multiple batch queues might be used by the scheduler to differentiate types of jobs depending on parameters such as job priority estimated Run time program lifecycle phase execution time resource requirements 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 See also Command pattern Command queue Job scheduler Priority queue DEFAULTSORT Batch Queue Category Job scheduling ... more details
Multiple issues unreferenced February 2007 wikify November 2009 orphan November 2009 Multi level queueing , used at least since the late 1950s early 1960s, is a queue with a predefined number of levels. Unlike the multilevel feedback queue , items gets assigned to a particular level at insert using some predefined algorithm , and thus cannot be moved to another level. Items get removed from the queue by removing all items from a level, and then moving to the next. If an item is added to a level above, the fetching restarts from there. Each level of the queue is free to use its own scheduling, thus adding greater flexibility than merely having multiple levels in a queue.

Unreferenced auto yes date December 2009 In modern computers many Process computing processes run at once. Active processes are placed in an array called a run queue , or runqueue . The run queue may contain priority values for each process, which will be used by the Scheduling computing scheduler to determine which process to run next. To ensure each program has a fair share of resources, each one is run for some time period quantum before it is paused and placed back into the run queue. When a program is stopped to let another run, the program with the highest priority in the run queue is then allowed to execute. Processes are also removed from the run queue when they ask to sleep , are waiting on a resource to become available, or have been terminated. In the Linux operating system, each CPU in the system is given a run queue, which maintains both an active and expired array of processes. Each array contains 140 one for each priority level pointers to doubly linked list s, which in turn reference all processes with the given priority. The scheduler selects the next process from the active array with highest priority. When a process quantum expires, it is placed into the expired array with some priority. When the active array contains no more processes, the scheduler swaps the active and expired arrays. In UNIX or Linux the Sar in UNIX sar command is used to check the run queue.
