Note : Answer any FIVE full questions.

1 a. Mention the two categories of parallel computers and explain them with their architecture.

b. Explain the different types of data dependence with an example for each.

2 a. Trace out the following program to detect parallelism using Bernstein’s conditions. Pi : C-DxE P2 : M-G + C P3 : A – B + C P4 : C = L + M P5 : F = G v E

Assume that each step requires 1 step to execute and 2 adders are available.

Compare between sequential and parallel execution of the above program.

b.  Define the following terms :

i) Grain packing ii) Coarse grain and iii) Fine grain.

c.   Explain how grain packing can be done to compute the sum of the 4 elements in the resulting product matrix C – A x B where matrices A and B are of order 2×2.

3 a. Discuss and compare the characteristics of CISC and RISC architectures.

b. Discuss and compare the following :

i) Base scalar processing,  ii) Super scalar processing and iii) Pipelining technique.

4 a. With respect to shared memory organization, explain the memory interleaving technique.
