(6 pts) A program P2 is executed on computer system B, which has a 2.8571429 GHz clock frequency. A programmer writes code to read processor performance monitoring registers after the program completes (Intel refers to the part of the CPU that can be used to collect run-time information as the Performance Monitoring Unit or PMU). The performance monitoring unit indicates that 23,118,471,971 user instructions were executed (just the instructions of P2 excluding OS and overhead instructions) in 53,866,039,692 clock cycles.

(a) What was the average CPI during the execution of P2?

(b) What was the IPC during the execution of P2?

(c) What was the user CPU time, in HH:MM:SS format, for P2?

    Design and implement a C Language program that measures the performance of given processors. There are several metrics that measure the performance of a processor. We will be using the following 3 measures: 1.CPI (clock cycles per instruction) = #clock cycles /#instructions 2.CPU execution time = #instructions x CPI x clock cycle time . cylce time = 1/CPU clock rate in hertz units 3.MIPS (mega instructions per second)= #instrucrions/ CPU X 1000000 Typically, processors’ performance is measured using a wide...
