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.
Consider the following processes:Process Arrival Time Service Time A 0 4 B 1 3 C 2 3 D 2 2 E 3 1 F 5 3 Show (draw the schedule, x-axis is time, and one row for each CPU) how the aboveprocesses execute over time on a system with 2 CPUs. Compute the average turnaroundtime for all processes and the average utilization for each CPU under each of the following schedulers: (a) FCFS with a single Ready Queue. A process gets scheduled once one of the CPUsis available. When both CPUs are available, we select CPU1. (b) FCFS with a Ready Queue per CPU. Processes A, B, and C go to CPU1 and processesD, E, and F go to CPU2. (c) HRRN with a single Ready Queue. A process gets scheduled once one of the CPUsis available. When both CPUs are available, we select CPU1.
Suppose there are five processes, their arrival time and running time are listed as follows. Adopt FCFS and SJF, respectively, give the schedule order and average waiting time.

Consider a computer system which 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 any way that is, two in one shot or one by one. The system always satisfies a request for a resource if enough resources are available. If the processes don't request any other kind of resource, show that the system never deadlocks?

Suppose a system has 5 processes, P = {P1, P2, P3, P4, P5}, and 4 resources, R = {R1, R2, R3, R4}, where there are 2 instances of R1, 1 instance of R2, 3 instances of R3, and 3 instances of R4. The current state of the system is defined by the following requests and assignments: P1 is requesting an instance of R3 and has been assigned an instance of R2; P2 is requesting an instance of R1 and has been assigned an instance of R3; P3 is requesting an instance of R4 and has been assigned an instance of R1 and an instance of R3; P4 is requesting an instance of R3; P5 is requesting an instance of R2 and has been assigned an instance of R4. Is there deadlock in this system? (Explicitly state yes, there’s deadlock or no, there isn’t.) If applicable, draw a wait-for graph or resource-allocation graph, and use the appropriate graph to justify your answer. If you conclude there is no deadlock, your justification should contain a sequence of execution for the processes which shows that…

A real-time system executing four different periodic tasks Ti(p,t) is given, with p and t representing the period and the execution time of the task, respectively. Each task's deadline matches its period p. The system is executing the following set of tasks: S = {T1(10,2), T2(4,1), T3(10,3), T4(7,1)}. Is this real-time system schedulable under Rate-Monotonic (RM) scheduling? Is this real-time system schedulable under Earliest Deadline First (EDF) scheduling?
