Question: 1. Two computers A and B whose clock rates are 3.3 GHz and 2.5 GHz respectively. Their running times of application_1 are 2 and 3

1. Two computers A and B whose clock rates are 3.3 GHz and 2.5 GHz respectively. Their running times of application_1 are 2 and 3 seconds respectively. From run time measurement, we know that the numbers of instruction executed in application_1 for these two computers are 2000 and 1500 million respectively.

(1) What is the instruction execution rate (instructions per second) of each computer for running application_1?

(2) What is CPI of each computer for running application_1?

(3) If the running times of application_2 are 4 and 3 seconds respectively for computer A and B, and they keep the same CPI as that of application_1, what is the instruction counts for application_2 running on each computer?

(4) Which computer is faster for each application and by how much?
