Assume that we are considering enhancing a machine by adding a vector mode (fraction enhanced) to it. When a computation is performed in vector mode, it is 20 times faster than the normal mode of execution. We call percentage of time that could be spent using vector mode the percentage of vectorization (fraction enhanced). a. What percentage of vectorization (fraction enhanced) is needed to achieve a speedup of 2? b. What percentage of vectorization (fraction enhanced) is needed to achieve one-half of the maximum speedup attainable from using vector mode? c. Suppose you have measured the percentage of vectorization (fraction enhanced) for programs to be 70%. The hardware design group says they can double the speed of vector rate with a significant additional engineering investment. You wonder whether the compiler crew could increase the use of vector mode as another approach to increasing performance. How much of an increase in the percentage of vectorization (fraction enhanced) (relative to the current usage) would the compiler team need to obtain the same performance gain? Which investment would you recommend
