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. Code MUST BE WRITTEN IN C/C++ #include <pthread.h> #include <stdio.h> #include <sys/time.h> #define NUM_THREADS 5 struct timeval tp_s, tp_e; struct timezone tzp_s, tzp_e; void *runner(void *param) { int i=0,j=0; long x; pthread_t tid= pthread_self(); struct timeval tp_s1, tp_e1; struct timezone tzp_s1, tzp_e1; printf(" %d…

3. Job Scheduling: Consider the problem of scheduling n jobs of known durations t1, t2, ..., tn, for execution by a single processor. The jobs can be executed in any order, one job at a time. You want to find a schedule that minimizes the total time spent by all the jobs in the system. (The time spent by one job in the system is the sum of the time spent by this job in waiting plus the time spent on its execution.) Design a greedy algorithm for this problem. Does the greedy algorithm always yield an optimal solution?

Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question:The Ricart& Argwala mutual exclusion algorithm: (a) Does not depend on time stamps in messages while Lamport's does. (b) Cannot handle the case where two or more processes request the same resource at the same time. (c) Does not require a process to send messages to the entire group while Lamport's does. (d) Requires fewer messages than Lamport's algorithm.
