Assignment requires that you should create a virtual machine in AWS (Amazon Web Services) to develop your programs to examine the performance of different pthread contention scope. Try to adopt two different pthread contention scope, process-contention scope, and system-contention scope, execute and compute the average turnaround time. Problem Statement According to the code attached in the document, rewrite the function runner that l The value of MAX is the last 8 number of your student ID l Display the turnaround time of each pthread of each scheduling algorithm l Please discuss the results of these scheduling algorithms.
