- Suppose a task consists of n subtasks Ji ’s, each of which has computation time Ci , i=1,...,n. This task requests service at time T and has absolute deadline D. Provide a formula to compute the latest start time for each subtask such that the deadline of the entire task can be satisfied. (Please type out the answer)For Scheduled Job, we can preset a time or an action with this to run the scheduled job: Group of answer choices Job Trigger Timer Preset ScheduleWe call the density of a task T, C/min(D, P), where C is the computation time, D is the relative deadline, and P is the period. Prove: A system of independent, preemptable tasks can be feasibly scheduled on one processor if its density is equal to or less than 1 (please type out the questions)
- 4a. . The task set is (3,1), (5,1), (7,1). Schedule using RM [again, you can end at t=20 or later] 4b. Now, a sporadic job comes at t=8. Its deadline is t=15. Can it be done? 4c. now, two aperiodic jobs come. One comes at t = 5, e = 2. The other comes at t = 10, e = 1. What are their response times?(Practice) You’re given the job of preparing a complete meal for five people next weekend. Determine a set of subtasks to accomplish this task. (Hint: One subtask, not necessarily the first, is buying the food.)Give a succinct explanation of the differences between short-, medium-, and long-term scheduling alternatives.
- What transpires if many tasks have the same priority?Question 7) Discuss the challenges and the merits of concurrent programming. You must considerthe effect of the interaction of processes and the effect of process scheduling.
