Repeat Problem 10.3d for the execution profiles of Table 10.9b. Comment on the results.
Consider a set of three periodic tasks with the execution profiles of Table 10.9a. Develop scheduling diagrams similar to those of Figure for this set of tasks that compare rate monotonic, earliest-deadline first, and LLF. Assume preemption may occur at 5-ms intervals. Comment on the results.
Answer to relevant QuestionsMaximum urgency first (MUF) is a real-time scheduling algorithm for periodic tasks. Each task is assigned an urgency that is defined as a combination of two fixed priorities and one dynamic priority. One of the fixed ...What is the difference between logical I/O and device I/O? The following equation was suggested both for cache memory and disk cache memory: TS = TC + M * TD Generalize this equation to a memory hierarchy with N levels instead of just 2. List and briefly define five file organizations. Some operating systems have a tree–structured file system but limit the depth of the tree to some small number of levels. What effect does this limit have on users? How does this simplify file system design (if it does)?
