Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

Please Implement in C programming Language Given the list of processes, their CPU burst times, arrival times, and priorities implement the SJF scheduling algorithm on the processes with preemption. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Waiting time: Processes need to wait in the process queue before execution starts and in execution while they get preempted. Turnaround time: Time elapsed by each process to get completely served. (Difference between submission time and completion time). Task 1: SJF Scheduling with preemption You can use the following input as a sample:

In this project, you'll implement one of the following CPU scheduling algorithms by writing a CPU simulator. Shortest Job First (SJF)(Non-preemptive)The shortest job first algorithm is a priority based scheduling algorithm that associates with each process the length of the process's next CPU burst. When CPU is available, it is assigned to the process that has the smallest next CPU burst. Shortest Remaining Time Next (SRTN)(Preemptive)The shortest remaining process next scheduling algorithm is the preemptive Shortest Job First algorithm. With this scheduling algorithm, the process in the ready queue with the shortest execution time is chosen to execute. If a "new process" arrives in the ready queue with a CPU service time less than the remaining time of the current process, preempt. First Come First Serve (FCFS) (recommended)The first come first serve algorithm is simplest CPU-scheduling algorithm. In this algorithm, the process at the head of the queue is allowed to execute until it…
Suppose a program segment consists of a purely sequential part which takes 100 cycles to execute, and an iterated loop which takes 400 cycles per iteration. Assume that the loop is dependent on the sequential part, i.e., both parts cannot run in parallel. Also assume that the loop iterations are independent, and cannot be further parallelized. If the loop is to be executed 100 times, what is the maximum speedup possible using an infinite number of processors (as many processors as you could possibly need) compared to a single processor?
