Engineering

A program is run on a computer with multiple processors. When a computation is run in parallel mode, it is 20 times faster than if the computation were done on a single processor.

a. What percentage of program execution must be run in parallel mode to achieve the overall speedup of one-half the maximum speedup attainable from using the parallel mode.

b. Draw the speedup graph (Y-axis) as a function of program fractions enhanced (X-axis) in increments of 0.05. By observing the graph, what conclusion can be made? (Use a package such as Excel for drawing the graph; no hand drawing).
