1.9. Parallel processing effectivenessConsider two versions of the task graph in Fig. 1.13. Version U corresponds to each node requiring unit computation time. Version E/O corresponds to each odd-numbered node being unit-time and each even-numbered node taking twice as long.a. Convert the E/O version to an equivalent V version where each node is unit-time.b. Find the maximum attainable speed-up for each of the U and V versions.c. What is the minimum number of processors needed to achieve the speed-ups of part (b)?d. What is the maximum attainable speed-up in each case with three processors?e. Which of the U and V versions of the task graph would you say is “more parallel” andwhy?
