Considering those two diagrams, explain any architecture performance bottlenecks that will limit system performance. Page 6 (20pts) 5.4 (5pts each) In the chapter Powerpoint, the idea of parallel processing was introduced, using multiple CPUs or core (or other processing units) to process computing faster a) For instance, given your workload is ten processes, and you have ten CPUs, what would be the expected maximum speedup you can obtain. b) Given one process in your workload, but ten CPUs, when would it be possible to speedup up a single process? 5.5 (Spts each) Research online Konrad Zuse and his Z1-24 .computers.
