Assume for arithmetic, load/store, and branch instructions, a processor has CPls of 1, 12, and 10, respectively. Also, assume that on a single processor, a program requires the execution of 2.56E9 arithmetic instructions, 1.28E9 load/store instructions, and 200 million branch instructions. Assume that each processor has 2 GHz clock frequency. 1. Assume that as the program is parallelized to run over multiple cores, the number of arithmetic and load/store instructions per processor is divided by O.6p (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, 8, 16 and 32 processors, and show the relative speedup of the 8, 16, and 32 processors result relative to the single processor result. a. b. If the CPI of the arithme tic instructions was doubled, what would the impact be on the execution time of the program on 1, 8, 16 or 32 processors
