- A concurrent application is required to take use of a multiprocessor.True or False.arrow_forwardReal 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.arrow_forwardPriority Scheduling resembles Shortest Job First Scheduling in what ways?arrow_forward
- Assume that there are the following processes in the deadline scheduler queue: Process Arrival Runtime Period Deadline 1 0 2 12 10 2 2 4 20 16 3 4 3 15 14 Complete the following schedule so each of the processes adheres to the deadline policy by replacing a dot with a process number (as necessary): TIME: 01234567890123456789012345678901234567890123456789 PROCESS: 112222333.......................................arrow_forwardReal-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.arrow_forwardDesign an Algorithms (psuedo c++) An algorithm that solves scheduling problem by brute forcearrow_forward
