Explain why you believe your program is correct. That is, explain what tests you performed to check the correctness.
Give explanations of your data. Explain what you think causes the difference between what you get and perfect linear speedup (i.e. perfect 100% parallel efficiency). Also, importantly, discuss the variation in the parallel efficiency. Does it uniformly decay as number of processes increases or not? why? What happens when the number of processes exceeds the number of processors?
Please staple all parts of your lab together, and label each piece. Be prepared to discuss your results on the day that the assignment is due.
