a) If the program execution time is 2 s, and that the number of Load instructions is 130,000 what is the clock cycle of the computer? At what frequency does the computer run?
b) How much does the CPI for the Store instructions have to be reduced to gain 30% reduction in execution time?
c) Assume that a computer system has a processor with 16 cores that can be used to solve a problem in parallel. 96% of the code is parallelizable. Can the system achieve a speedup of 10? How many cores are needed for this performance?
