Real Time Scheduling: Select all statements below that are true EDF scheduling assigns the highest priority to a process with the smallest remaining time until its deadline. RM scheduling assigns a higher priority to processes with shorter periods. Rate Monotonic (RM) scheduling works by dividing the total amount of time available into an equal number of shares, and then each process must request a certain share of the total when it tries to start. If a process has period p, it is activated every p units of time. A real-time system is schedulable under Earliest Deadline First (EDF) when its overall CPU utilization is less than or equal to 1. A real-time system is schedulable under RM when its overall CPU utilization is less than 1.

For each ofthe scheduling policies, compute and print the completion Time(CT), Turnaround Time(TAT),and Waiting Time(WT) for each process using C Programming.Waiting time: Processes need to wait in the process queue before execution starts and inexecution while they get preempted.

In a timesharing OS we have the following cpu timeline for two tasks X and Y. The timeslice is 1s.Both tasks are available in the system at the same time t=9:00:00.000 and order of arrival is the obviousX followed by Y. (The decimals reflect milliseconds if they showup in an indicated time reference.) There are no other processes (tasks) in the system other than X,Y. 1234567890 XYXYX--YXY The time line 1 indicates that at t=9:00:00s task X starts its execution and when t=9:00:01s is reached task Y takes over. The time line 1 indicates the 'first second' and time line 0 indicates the 'tenth second' above.Task Y completes its execution at t=9:00:10s, the completion of the tenth second since X started its execution. Task X has completed its execution earlier. (a) What is the total number of context switches starting from prior to t=9:00:00s (e.g. t=8:59:59.999) through thecompletion of $Y$? answer is 16s (b) What is the turnaround time for Y? answer is 10s (c) What is…
Scheduling Algorithms This project involves implementing several different process scheduling algorithms. The scheduler will be assigned a predefined set of tasks and will schedule the tasks based on the selected scheduling algorithm. Each task has an arrival time and is assigned a priority and CPU burst. The following scheduling algorithms will be implemented: First-come, first-served (fcfs), which schedules tasks in the order in which they request the CPU . Shortest-job-first (sjf), which schedules tasks in order of the length of the tasks’ next CPU burst. Priority scheduling (pri), which schedules tasks based on priority. Round-robin (rr) scheduling, where each task is run for a time quantum (or for the remainder of its CPU burst). Priority with round-robin (pri-rr), which schedules tasks in order of priority and uses round-robin scheduling for tasks with equal priority. Priorities range from 1 to 10, where a higher numeric value indicates a higher relative…
A single-CPU system has four processes, P1, P2, P3 and P4 in the ready queue. The execution times and I/O needs for these processes are given below. All times are in ms. (hint: when a process starts an IO operation, it is removed from the ready queue and put back at the end of the queue only when it completes its IO). Process P1: Arrives at 0ms, needs 23ms of CPU time. Performs I/O for 5ms after 10ms of its execution time, then another 5ms after 20ms of its execution time. Process P2: Arrives at 3ms, needs 12ms of CPU time. Performs I/O for 10ms after 5ms of its execution time. Process P3: Arrives at 1ms, needs 15ms of CPU time. Performs I/O for 1ms after 7ms of its execution time. Process P4: Arrives at 2ms, needs 8ms of CPU time. Performs I/O for 5ms after 4ms of its execution time. We assume that the CPU is idle if no one of these four processes is using it. Using Round Robin scheduling algorithm with a Time Quantum of 4ms and ignoring the context switch time, determine: a) The…
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.
Multiprocessor systems use multiple CPUS to perform various tasks. This increases throughput and reduces response time. In this problem, a multiprocessor system has a certain number of processors. Each processor has the ability to schedule a limited number of processes in one second. However, after this scheduling, the processor's ability is reduced to floor(ability/2). Given the processor's abilities and the number of processes, what is the minimum time required to schedule all the processes in the system? Example n = 5 (number of processors and size of ability[]) ability = [3, 1, 7, 2, 4] processes = 15 This optimal solution is: 1. First, the processor with ability = 7 schedules 7 processes in one second. Now, ability = [3, 1, 3, 2, 4] because 7 was reduced to floor(7/2). There are 15 - 7 = 8 remaining processes. 2. Second, the processor with ability = 4 is used. After that, ability = [3, 1, 3, 2, 2]. Remaining processes = 8 - 4 = 4. 3. Third, a processor with ability = 3 is used.…
CPU scheduler will decide which process should be given the CPU for its execution. For this it uses different algorithm to choose among the process. One among that algorithm is FCFS algorithm. In this algorithm the process which arrives first is given the CPU after finishing its request only it will allow the CPU to execute another process.

In this project, you'll implement one of the following CPU scheduling algorithms by writing a CPU simulator. Shortest Job First (SJF)(Non-preemptive)The shortest job first algorithm is a priority based scheduling algorithm that associates with each process the length of the process's next CPU burst. When CPU is available, it is assigned to the process that has the smallest next CPU burst. Shortest Remaining Time Next (SRTN)(Preemptive)The shortest remaining process next scheduling algorithm is the preemptive Shortest Job First algorithm. With this scheduling algorithm, the process in the ready queue with the shortest execution time is chosen to execute. If a "new process" arrives in the ready queue with a CPU service time less than the remaining time of the current process, preempt. First Come First Serve (FCFS) (recommended)The first come first serve algorithm is simplest CPU-scheduling algorithm. In this algorithm, the process at the head of the queue is allowed to execute until it…
Q3: Suppose there is a processing unit composed by CPU and I/O component. For a specific task, CPU takes 5 second to finish the execution and I/O takes 2 second to process. The communication time between CPU and I/O can be elimiate under this circumstance. Execution Time 7 second 5second 2 second CPU time I/O time If CPU time decreases by 25% per year for 3 years and I/O time decreases by 20% per year 1) How many times faster is this program after 3 years? 2) What percentage of new time is I/O? and what percentage of new time is CPU?
Please Implement in C programming Language Given the list of processes, their CPU burst times, arrival times, and priorities implement the Round Robin scheduling algorithm on the processes with preemption. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Waiting time: Processes need to wait in the process queue before execution starts and in execution while they get preempted. Turnaround time: Time elapsed by each process to get completely served. (Difference between submission time and completion time).
Suppose you are given n tasks J = {j1, j2, · · · jn}.Each task ji has two parts - a preprocessing phase which takes pi units and a main phase whichtakes fi units of time. There are n machines that can execute the main phases of the jobs in parallel.However, the preprocessing phases need to be executed sequentially on a special machine. Thecompletion time of any schedule is the earliest time when all tasks have finished execution. Designa greedy algorithm which produces a schedule that minimizes the completion time. Here, youneed to give formal proof of correctness. Your proof should not exceed one side of an A4 sheet.Anything more than that will not be considered by the evaluator. Provide only pseudocode.
