Assume for arithmetic, load/store, and branch instructions, a processor core has CPIs of 1,12 and 5 respectively. Also assume that on a single processor core a program requires the execution of 2.56E9 arithmetic instructions, 1.28E9 load/store instructions, and 256.0E6 branch instructions. Assume all processor cores run at 2 GigaHertz. Assume that, as the program is parallelized to run over multiple processor cores, the number of load/store instructions per processor core is divided by .5 times p for all number of...
