Let the processes P1, P2, P3, and P4 be given. They arrive in the system at the same time in this order. The processes have the following service times (in time units): Process P1 P2 P3 P4 Service time (CPU burst) 53 17 68 24 For the scheduling method "Shortest Job First" (SJF), specify the execution order of the processes, the average execution time (average turnaround time) and the average waiting time over all processes. You must show your calculations. You will not have to draw Gantt charts.
In executing Jobs A and B using the priority scheduling algorithm, what will happen ifboth jobs have:a. unequal priorities but equal CPU cycles?b. equal priorities but different CPU cycles?
Apply the following scheduling algorithms to the list of processes above.• First-Come First-Serve• Shortest Remaining Time First• Round Robin: Quantum = 3
Please help with implementing the Banker's algorithm for deadlock avoidance, that works on a given set of N processes and M resource types (N<10,M<10). Use Java for the implementation, with a simple text interface, where the user enters only the name of the input file (text only). The program reads all the necessary input data from that file. The input data and result is then displayed on the screen. Please help by using BACKTRACKING and find all solutions Subject: Java Programming
Is it possible for a single process to halt in the middle of its execution? Justifications for your responses are required.
On a real computer system, neither the resources available nor the demands of processes forresources are consistent over long periods (months). Resources break or are replaced, newprocesses come and go, new resources are bought and added to the system. If deadlock iscontrolled by the banker's algorithm, which of the following changes can be made safely(without introducing the possibility of deadlock), and under what circumstances?a) Increase Available (new resources added).b) Decrease, Available (resource permanently removed from system).c) Increase Max for one process (the process needs more resources than allowed; it maywant more).d) Decrease Max for one process (the process decides it does not need that manyresources).e) Increase the number of processes.
Given the list of processes, their CPU burst times, arrival times and priorities implement SJF,Priority and Round Robin scheduling algorithms on the processes with preemption. For each ofthe scheduling policies, 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 inexecution while they get preempted. Turnaround time: Time elapsed by each process to get completely served. (Difference betweensubmission time and completion time).
The following program consists of 3 concurrent processes and 3 binary semaphores. The semaphores are initialized as S0 =1, S1= 0, S2=0 Process P0 Process P1 Process P2 wait(S0); print '0' release(S1) release (S2);} wait(S1); release(S0); wait(S2); release(S0); How many times will process P0 print ‘0’?
Four processes arrive at the same time with their priorities, execution times and I/O times given in the table below. Assuming a Round-Robin Scheduling works with a quantum time of 3, but the scheduler selects the process with highest priority from the queue (NOT those arrived earliest), other than currently pre-empted process, at each turn; a-)Draw the timeline for CPU- and I/O- bursts for these processes b-)Calculate average turn-around time
The ready queue is subdivided into many queues by the multilevel scheduling algorithm, and each of these queues has its own scheduling technique or policy. Choose one: Is it accurate or erroneous? The time a process spends waiting should be minimised by the CPU scheduler. Choose one: OFalse O True
The following program consists of 3 concurrent processes and 3 binary semaphores. The semaphores are initialized as S0 = 0,S1 = 1 and S2 = 1. Process P0:while (true) { wait (S0); print '1';release(S1);release(S2);} Process P1:wait (S2);release (S0); Process P2:wait(S2);release(S0); How many times will process P0 print '1'?
1. Write a LINUX C Program for the Implementation of shortest remaining time first (SRTF) Scheduling Algorithm. Note: - Please keep in mind that the higher the priority number, the higher the priority. If the priority of two processes is the same, sort according to process number.
