Answer: subculture
Explanation:
The community is an example of subculture.
A subculture is a group of people within a culture that differentiates itself from the parent culture to which it belongs, often maintaining some of its founding principles. Subcultures develop their own norms and values regarding cultural, political and sexual matters.
subcultures might include hippies, Goths, fans of hip hop or heavy metal and even bikers.
Answer:
Given that Program instructions consists of:
- 60% floating point multiply
- 20% floating point divide
- 20% other instructions
Amdahl's law states that:
Execution time affected by improvement = (Execution time after improvement/ Amount of improvement) + (Execution time unaffected)
Assuming initially that floating point multiply, divide and other instructions have same clocks per instruction (CPI).
Part (a)
New execution time after improvement with multiply = (60) / 8 + (20 + 20) = 47.5
New execution time after improvement with Divide = (20) / 3 + (60 + 20) = 86.67
New system should be 4x faster which means new execution time should be below = 100/ 4 = 25.
Therefore, Management's goal can NOT be achieved by making the improvement with multiply or divide alone.
Part (b)
New execution time after improvement with multiply and divide = (60 / 8) + (20 / 3) + 20 = 34.17
Speed up = execution time of original machine / Execution time of new machine = (100 / 34.17) = 2.93
Therefore, new machine is 2.93 times faster than original machine.
