Real-time Scheduling: Pick all verifiable claims. Time is divided into equal portions using Rate Monotonic (RM) scheduling, which necessitates that each process first seek a chunk. Real-time systems with CPU utilisation below one are scheduled by RM. Earliest Deadline First (EDF) may schedule a real-time system when CPU utilisation is less than 1. Every pth time unit, a new process is started. Shorter processes are prioritised through RM scheduling. The quickest procedures are given priority in EDF scheduling.

Scheduling is a method that is used to distribute valuable computing resources, usually processor time, bandwidth, and memory, to the various processes, threads, data flows and applications that need them. Scheduling is done to balance the load on the system and ensure equal distribution of resources and give some prioritization according to set rules. This ensures that a computer system is able to serve all requests and achieve a certain quality of service. With this regard, Discuss the usefulness of Gantt charts in the scheduling process.
Part IV: Scheduling. Suppose that processes P1, P2, ..., P4 arrive for execution at the times indicated in Table below. Each process will run for the amount of time listed, and will be assigned a priority ranging from 0 (highest) to 10 (lowest). No more processes will arrive until the last process completes. In answering the questions, base all decisions on the information you have at the time the decision must be made. Arrival Time Process Priority Burst Time 8 P1 P2 10 4 5 P3 5 P4 8 2 1 1) Draw two Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: a) Non-preemptive Priority b) Round Robin (Quantum time is 4) c) What is the waiting time for non-preemptive Priority scheduling algorithm?
Real-time Scheduling: Choose all true assertions. Rate Monotonic (RM) scheduling divides time into equal parts and requires each process to seek a portion upon starting. RM schedules real-time systems with CPU utilization below 1. When CPU utilization is less than 1, Earliest Deadline First (EDF) may schedule a real-time system. A process is initiated every p time unit. RM scheduling prioritizes shorter processes. EDF scheduling prioritizes processes with the shortest time frame.

The following processes are being scheduled using a preemptive, roundrobin scheduling algorithm. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. In addition to the processes listed below, the system also has an idle task (which consumes no CPU resources and is identified as Pidle ). This task has priority 0 and is scheduled whenever the system has no other available processes to run. The length of a time quantum is 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue.

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 0 being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict. Also,…

A system contains five tasks. There are three resources X, Y, and Z. The resource requirements of the tasks are specified as follows: T: [X; 1] [Y; 2]. T;: [Z; 4]. T3: [X; 2]. T4: [X, 2][Y; 3]. T3: [X; 1] [Z; 3]. The tasks are indexed in the decreasing order of priorities and scheduled with the priority ceiling protocol. Find the maximum blocking time for each task.
