Suppose that we wish to achieve a speedup greater than 4 for an application that is 60 percent parallel and 40 percent serial. Colleague A proposes that we add as many processing cores as the budget allows. Colleague B proposes that we restructure the application code to reduce the portion of the application that must run serially before adding more cores. Whose proposal is supported by Amdahl’s Law? Justify your answer.
