Which of the following is not an optimization criterion in the design of a CPU scheduling algorithm?

Which of the following is not an optimization criterion in the design of a CPU scheduling algorithm? Correct Answer Minimum CPU utilization

The correct answer is option 1.

CONCEPT

Maximum CPU utilization, maximum throughput, minimum turnaround time, and Minimum waiting time are the optimization criterion in the design of a CPU scheduling algorithm

Key Points.

CPU utilization:

In an ideal world, the CPU will be busy 100% of the time, wasting no CPU cycles. On a real machine, CPU utilization should be between 40% and 90%.

Throughput

It is the number of processes completed in a given amount of time. Depending on the processes, rates can range from 10/second to 1 hour.

Turnaround time

It is the amount of time it takes for a process to complete from start to finish.

Waiting time:

The number of time processes spend waiting in the ready queue for their turn to use the CPU.

In general, the average value of criteria should be optimized (Maximize CPU utilization and throughput and minimize all the others.)

However, there are periods when it is desirable to do something different, such as reduce the maximum response time.

Hence the correct answer is Minimum CPU utilization.

One of the Scheduling method is also known as Shortest-­next­-CPU­-burst algorithm, because scheduling through this method depends on the length of the next CPU burst of a process rather than its total length. Which of the following scheduling method is being discussed here?
You install and run a third-party 32-bit application named Application on your Windows 2000 Server computer. After several days, the application stops responding. You open Task Manager and find that the CPU usage is at 100 percent. The normal range of CPU usage on the server is from 20 percent to 30 percent You end the application. However, you see that the CPU on the server is still at 100 percent. Task Manager shows no other applications running. You then examine the Processes page in Task Manager and confirm that the Application.exe process is no longer running. You want to return the CPU usage to its normal range. What should you do?
