WebThis time is commonly referred to as time-slice (aka quantum). A task can not run longer than the time-slice. In case a task has not completed by the end of its dedicated time … WebAs you see, the time slice of each task in the run queue is no longer dependent on its weight value and thus each task will receive the same time slice. This is the first case the book mentions. The second case mentions the nice values differ, and thus the weight values will differ. Each task will receive its time slice accordingly.
