Q1 Work problem 10.8 (Software Engineering Economics) Ans Since N max = S-P+M/2M a) Increase processor speed S If we increase the processor speed S then N max also increases because keeping all parameters constant here N max is directly proportional to S thus if S increases N max also increases. Eg when S is 1100 Nmax is coming out to be 6.125 and so on ,keeping P=200 and M =80 here. s Nmax 1100 6.125 1200 6.75 b) Increase processor overhead P On increasing P ,N max decreases. Eg keeping S =1000,M=80 and P=200 we have Nmax= 5.5 but P Nmax 300 4.875 400 4.25 500 3.625 c) Decrease multiprocessor overhead M On decreasing M ,Nmax increases, keeping S=1000,P=200 ,eg M Nmax 60 7.16 40 10.5 20 20.5 d) Increase required operations/transaction T Here this will have no effect on Nmax because Nmax doesnot depends on T.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
