Assuming that there are 5 processes (P1, P2, P3, P4 and P5) which are processed by a CPU.The processes need 3 resources (A, B and C). The following information shows the current resources allocated to each process and also the maximum resources they required in order to complete their processes.

Hey, I have already received a good answer to this question but I am looking for greater detail to be provided. There are three processes P1, P2 and P3 are running in a system with 3 instances of a resource R1, 2 instances of a resource R2, and 2 instances of a resource R3. At a given time the allocation matrix is: A = [{1, 1, 1} { 0, 1, 0} { 1, 0, 0 }] Assume that the maximum matrix is M = [ {2,2,1} {1,1,1} {3,1,0}] While in this state, a new process P4 is created which requires at most 2 instances of R1 and one instance of R2. This process initially requests one instance of R1 to be allocated to it. Using the Banker’s algorithm, determine whether this request can be granted or must be refused.
(i) Describe Banker’s algorithm for deadlock avoidance with supporting example Consider a computer system with has four identical units of a resource R. There are three processes each with a maximum claim of two units of resource R. Processes can request these resources in anyway, that is, two in one shot or one by one. The system always satisfies a request a request for a resource if enough resources are available. If the process doesn’t request any other kind of resource, show that the system never deadlock Give a solution for the following synchronization problem using semaphores Producer- Consumer Problem Readers- Writers Problem List out the issues in preprocessor scheduling that causes performance degradation in multiprocessor systems
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.

Suppose that an operating system supports two kinds of sequential processes: high-priority interactive processes, and low-priority non-interactive processes. The behavior of the high-priority processes is to alternate between periods of computation of duration Tc and periods of blocking (waiting for input) of duration Tb. The behavior of the low-priority processes is to compute constantly, with no blocking. The operating system’s scheduling policy is round-robin with a quantum q, where Tc < q. Scheduling decisions are made only when a quantum expires, or when the running process blocks. The scheduler selects a low-priority process to run only if no high-priority processes are ready. Suppose there is one high-priority process and one low-priority process in the system, and that both processes will run for a long time. For what fraction of the time does the low-priority process run?

Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF, and RR (quantum = 3). What is the turnaround time of each process for each of the scheduling algorithms in part a? what is the waiting time of each process for each of the scheduling algorithms in part a? Which of the algorithms results in the minimum average waiting time (over all processes)?
