Priority array, Computer Engineering

Assignment Help:

The runqueue is the list of runnable processes on a given processor. There is only one runqueue per processor. Each runqueue contains two priority arrays: Active and Expired. Each priority array contains one queue of runnable processes per priority level. Each array has 140 levels, thus 140 queues. A process with priority level 125 will go to the _125th _ queue. In this project, we will not implement all 140 queues. We will only implement a single queue. In the real Linux scheduler, each queue represents one priority level. In our project, we will have a single data structure. The active array contains processes that have yet to exhaust their time slice. Once their time slice is exhausted, it will go to the expired array. There is also an  IO queue. This queue is used to hold processes that are using IO. There will be no waiting for access to IO devices.

Thus, all the processes in the IO queue can decrease their IO burst in each clock tick.
