Priority Non-preemptive Scheduling

In the Non Preemptive Priority scheduling, The Processes are scheduled according to the priority number assigned to them. Once the process gets scheduled, it will run till the completion. Generally, the lower the priority number, the higher is the priority of the process. The people might get confused with the priority numbers, hence in the GATE, there clearly mention which one is the highest priority and which one is the lowest one.

Advantages of Non-preemptive Scheduling

Here, are pros/benefits of Non-preemptive Scheduling method:

• Offers low scheduling overhead
• Tends to offer high throughput
• It is conceptually very simple method
• Less computational resources need for Scheduling

Disadvantages of Non-Preemptive Scheduling

Here, are cons/drawback of Non-Preemptive Scheduling method:

• It can lead to starvation especially for those real-time tasks
• Bugs can cause a machine to freeze up
• It can make real-time and priority Scheduling difficult
• Poor response time for processes
