Draw an activity network and find the critical path for a research project given below.There are eight tasks in a small project. Task A takes 14 days to complete. Task B takes 16 days to complete and can be executed in parallel with Task C which takes 22 days to complete. When tasks B and C are completed, task D can be executed which will take 17 days to complete. When D is completed, tasks E and F can be executed which will take 13 and 10 days to complete. When tasks E and F are completed, task G can be executed which will take 15 days to complete. (Note: Highlight the critical path in the network)
2. Given the task set in Table 2, determine a feasible cyclic-executive schedule. Period P = 30 and frame length f = 3. (suppose the first release times of 3 tasks are 0, 2, and 3) Task Period Deadline Execution Time 1 15 3 3 2 10 5 3 3 6 6 3 Table 2: A task set and schedule
Consider the following task set. Task T T1 1 3 T2 2 4 T3 1 6 Using a timeline, show how a cyclic executive can be constructed for the task set. You may assume that the tasks can be arbitrarily “split up", but only at integer execution-time points. Thus, cach split-part of a task will have an integer execution time.
Consider the task set in Table 1. a) Assume one of the tasks in Table 1 has its deadline reduced by 1. Now, what is the most efficient schedulability test for determining whether the task set in Table 1 is schedulable under preemptive RM?
