Abstract
A system provides a task scheduler to define a priority queue with at least one window and a queue-window key. Each window is an ordered collection of tasks in a task pool of the priority queue and is identified by the queue-window key. The task scheduler sets a task-window key equal to a user-window key when the user-window key is greater than the minimum queue-window key. The task scheduler can further set the task-window key equal to the minimum queue-window key when the user-window key is less than the minimum queue-window key. A maximum task limit per user for each window and a priority increment for the user-window key are further applied to ensure fair scheduling.
