Computer Architecture

1. Consider the two computers and programs in problem 1. The following additional measures were made:

Find the instruction execution rate (instructions per second) for each computer when running program 1. [2 pts]

Suppose you wish to run a program P with 7.5 x 10^9 instructions on a 5 GHz machine with a CPI of 0.8. [4 pts]

a. What is the expected CPU time?

b. When you run P, it takes 3 seconds of wall clock time to complete. What is the percentage of the CPU time P received
