COMPUTER ORGANISATION

Determine the final grade of a student in the following scenarios: He/She gets 60/60 for Part A and 49/100 for Part B; He/She gets 50/60 for Part A and 71/100 for Part B; He/She gets 47/60 for Part A and 99/100 for Part B; He/She gets 53/60 for Part A and 51/100 for Part B; Suppose a task consists of 40% CPU access, 20% memory access and 40% disk access. A CPU with 8 cores provides an effective speedup of only 4 over a single core CPU. What is system speed up (as defined by Amdahl's law) when the 8-core CPU is used in place of the single core CPU?

Explanation / Answer

1 I am assuming following

90-100% Grade A

80-89% Grade B

70-79% Grade C

60-69% Grade D

0-60% Grade F

a) Grade in A is A, Grade in B is F. Total GPA = (4+0)/2 = 2 = C

b) Grade in A is B, Grade in B is C. Total GPA = (3+2)/2 = 2.5 = C

c) Grade in A is C, Grade in B is A. Total GPA = (2+4)/2 = B

d) Grade in A is B, Grade in B is F. Total GPA = (3+0)/2 = 1.5 = D
