For vectorization, efficiency is defined as the ratio of the speedup to the vector length. Determine the efficiency for each of the results in Problem 12.5. Comment on the variation of the efficiency with the vector length Reference of problem 12.5 With reference to Figure 12.1, assume an array size of N 32. Let all instructions require one time unit to execute in a processor. Determine the speedup of vectorization for vector lengths of 4, 8, 16, and 32 Reference of fig. 12.1 for (i :0;i
