Assume for arithmetic, load/store, and branch instructions, a processor has CPIs of 1, 12, and 5, respectively. Also assume that on a single processor a program requires the execution of 2.56E9 arithmetic instructions, 1.28E9 load/store instructions, and 256Million branch instructions. Assume that each processor has a 2GHz clock frequency. Assume that, as the program is parallelized to run over multiple cores, the number of arithmetic and load/store instructions per processor divided by 0.7xp (where p is the number of processors) but the number of branch instructions per processor remains the same. Find the total execution time for this program on 1, 2, 4, and 8 processors, and show the relative speed up of the 2, 4, and 8 processor results relative to the single processor result If the CPI of arithmetic instructions was doubled, what would the impact be on the execution time of the program on 1, 2, 4 and 8 processors
