As an IT manager, you need to host a web service as part of your duty. You need to decide between choosing Server A or Server B to host the web service. Server A contains 2 high-power 4-GHz processors and Server B contains 8 low- power 2-GHz processors. The high-power and low-power processors differ only by clock rate and that each processor can independently serve a different web request. For simplicity, suppose that the web requests are identical; handling each web request requires a processor to execute an identical stream of 1 billion instructions at a CPI of 2.

a) Suppose the web service to be hosted receives a burst of 2 web requests at a time. Which server will complete each burst of 2 requests faster and is, therefore, the better choice? For simplicity, assume the interval between two bursts of requests is very large. Justify your answer quantitatively.

b) Suppose the web service to be hosted receives bursts of 4 web requests at a time, instead. Which server will complete a burst of 4 requests faster and is, therefore, the better choice? Justify your answer quantitatively.

c) Suppose the web service to be hosted receives bursts of 8 web requests at a time, instead. Which server will complete a burst of 8 requests faster and is, therefore, the better choice? Justify your answer quantitatively
