Please answer the following questions related to Detection Algorithm. Given the below information, fill out Matrixes Request and Work. • Five processes P, through Pa; three resource types A (7 instances), B (2 instances), and C (6 instances) Snapshot at time To: Allocation Request Available Request satisfy safety criteria? Why??
Suppose that the following processes arrive for execution at the times indicated. Each process will run for the amount of time listed. In answering the questions, use preemptive scheduling, and base all decisions on the information you have at the time the decision must be made. Process P1 P2 P3 P4 P5 Arrival Time 0 2 4 6 8 Burst Time 12 4 8 2 6 What is the average waiting time for these processes with the Shortest-Job-First scheduling algorithm?
Process PI P2 P3 P4 P5 Buast time 2 1 8 4 5 Priority (2*xx) %5 (2xxx) 5 (2*XX) 0/0 5 (2*XX) do 5 (2*xx) do 5 ✓ 11 Value of XX is 5 All processes Arrives at time + = 0 ms. Draw the Gantt chart for priority scheduling (A larger priority number implies higher priority)
In the following resource allocation graph, are the processes deadlocked? If “yes” explain why and state which processes are involved in deadlock. If “not” explain why.
Eight batch jobs arrive almost at the same time in the following order: I₁, 2, ..., II8. The table below contains their running times and priorities: Job П1 П2 П3 П4 П П П П Running time (in min) 4 5 5 10 8 10 7 Priority 1 7 5 2 8 6 4 3 The highest priority is 1. For each of the following scheduling algorithms, determine the order of execution of processes and the mean process turnaround time: (a) priority scheduling; (b) first-come, first-served; (c) shortest job first. Scheduling is non-preemptive.
Consider the following snapshot of a system: Allocation Маx Available ABCD ABCD ABCD PO 2001 4212 3321 P1 3121 5252 P2 2103 2316 P3 1312 1424 P4 1432 3665 a. Illustrate that the system is in a safe state by demonstrating an order in which the processes may complete.
In the resource allocation graph below the letters A, B,..., I represent processes while numbers 1, 2,..., 9 represent resources. An arrow going from a resource to a process means that the process holds the resource. F 2 3 B 6 9 (E) 7 4 H 8 (a) Find all processes (in the graph above) which are in a deadlock. (b) We may kill one or more processes to break the deadlock. Which process should be killed? (c) Assume that there are four processes labeled A, B, C, D and four resources labeled 1, 2, 3, 4. Draw the resource allocation graph for the following sequence of requests. (The resource is assigned to the first process that requested it.) process B requests resource 2; process C requests resource 1; process A requests resource 2; process C requests resource 4; ⚫process A requests resource 3; ⚫process D requests resource 4; ⚫process B requests resource 3; process D requests resource 1. Which of the above processes are in a deadlock? Justify your answer.
When a stalemate occurs, those processes should be terminated, with the following outcomes:
In the following resource allocation graph, are the processes deadlocked? If “yes” explain why and state which processes are involved in deadlock. If “not” explain why.
