Do question C and D

Q2 (a) Write True (T) or False (F) on each sentences below: (i) The multi-core processor can run several and entirely different code threads. (0.5 marks) (ii) Typical modern personal computers now have between two and eight cores that enable multiple tasks (threads) to be executed sequently. (0.5 marks) (iii) Multi-core processor architecture means that two or three execution cores are positioned within a single processor. (0.5 marks) (iv) In general, multi-core processors are less energy efficient than separate multiple processors. (0.5 marks) (b) Explain the reason central routers has higher load than the edge router for Mesh topology compare to Torus topology using suitable diagram. (4 marks) Based on the following statement, respond it with your own opinion by adding ONE (1) advantages and disadvantages on both situation. Applications that has large amount of ILP (instruction-level parallelism) can be executed in a core that has the ability to exploit ILP (a core tha ssue multiple instructions per second, a wide-issue super scalar CPU). This core will optimize power consumption of the processor. But, this core certainly will not be a good choice for the applications which have little amount of ILP, resulting wastage of power compare to the other simpler core that has the low power consumption characteristics due the ability to handle applications with less ILP. If all cores are similar (just simply copy of a core) then there is no way to exploit resource constraint feature of application. (6 marks) (d) As Computer System Engineer, you are given 10 core 2.33GHz system and 4.22GHz 4 core to run an applications running in parallel. Analyse the advantages and disadvantages of both systems. (6 marks)
