When parallelizing an application, the idea speedup is speeding up by the number of processors. . If 75% of the application execution time is parallelizable, what is the overall speedup with 4 processors? For (a), what percentage of application execution time (after the parallelizing) is parallelized? If only 50% of the application execution time is parallelizable, at least how many processors is needed to achieve an overall speedup no less than that obtained in (a)
