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?
To not let any process wait longer than 500 ms, a system developer programs the Round Robin procedure with a dynamic time quantum size. With ‘n’ processes ready, the time quantum Q is set to 500 ms/n. What do you think of this scheduling strategy? (In which situations is this strategy feasible, and when is it not? Are there edge cases?) Explain your reasoning.
b.Start from the resource allocation state in Q 13. If a request from a process P3 arrives for (1, 2, 3), can the request be immediately granted ? Why or why not ? c.Start from the resource allocation state in Q 13. Suppose that P4 asks for 2 instances of resource B. Can the system grant this if it wants to avoid deadlock ? Explain.
Do Execution Paths 3 and 4 encompass the first three conditions for a deadlock to occur? Explain your answer.
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.
Let the processes P1, P2, P3, P4, and P5 be given. They arrive in the system at the same time in this order. The processes have the attached service times (in time units) and priorities. For each of the scheduling methods (First Come, first served (FIFO), Shortest Job First, Round Robin, and Priority Scheduling), specify the execution order of the processes and the average execution time (average turnaround time) for all processes. First, determine and state the execution times of the individual processes and then calculate the average value. Note: • For Shortest Job First, If the required service time (CPU time) is the same for two or more processes, use First Come, first served to resolve the conflict. • For Round Robin, the time quantum q = one time unit. • For Priority Scheduling, low integer priority values signify high priorities, with O being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict. Also,…
Given a system of 4 processes with a set of constraints described by the following precedence relation: › : {(P1, P3), (P1, P4), (P2, P4)} The processes access memory locations according to the table attached. Answer the following questions about the system (you are not required to draw any graphs): 1. Is the system determinate for all interpretations of its processes? Explain why. 2. Is the process pair (P3, P4) mutually non-interfering (MNI)? Explain why. 3. If the process pair (P3, P4) is not MNI, what modifications are necessary to guarantee that the system is determinate for all interpretations?
A process should be allowed to access only those resources for which it has authorization. Furthermore, at any time, a process should be able to access only those resources that it currently requires to complete its task. This is commonly referred to as the need-to-know principle, or domain of protection. Discuss this “domain” and its structure, including the following: Whether the relationship between a process and a domain is static or dynamic Domain switching How domain switching happens in the following cases: Each user is a domain Each process is a domain Each procedure is a domain
