3. Assume that a processor has the following CPIs, arithmetic ops(1), load/store(12), branch instructions(5). Consider a program that requires 106 arithmetic ops, .5 106 load/stores and .3 106 branch instructions. Each processors has a clock frequency of 2Ghz. Assume that the program is parallelized to run over multiple cores, the number of arithmetic and load/store instructions is divided by .6*p, where p is the number of processors. The number of branch instructions remains the same in each processor. (2*5-10) a) Find the total execution time for this program on 1,2,4 and 8 processors and show the relative speedup (b) If the CPI of the arithmetic instructions was doubled what would be the impact on the execution time of the program on 1,2,4 or 8 processors 3.
