  1. 7 Marks
    aExplain Flynn's classification of parallel computers with examples. How does it impact system performance evaluation?
  2. 7 Marks
    bCompare multiprocessors and multicomputers in terms of architecture and use cases.
  3. 7 Marks
    aDifferentiate between CISC and RISC architectures. Why is RISC preferred in modern high-performance computing?
  4. 7 Marks
    bA memory system has a 90% cache hit rate with 5 ns access time. Main memory access takes 100 ns. Calculate effective access time.
  5. 7 Marks
    aWhat are Pipeline hazards? Discuss techniques to minimize control hazards in instruction pipelining.
  6. 7 Marks
    bExplain Tomasulo's algorithm and its role in dynamic instruction scheduling.

  10. 7 Marks
    bHow do parallel compilers optimize code for concurrent execution?
  11. 14 Marks
    Numerical: A 5-stage pipeline has clock cycles of 2 ns, 3 ns, 4 ns, 3 ns, and 2 ns. Calculate speedup for 100 instructions over non-pipelined execution.
  12. 7 Marks
    aExplain SIMD organization and its applications in vector processing.
  13. 7 Marks
    bDiscuss challenges in multithreading and how multiple-context processors address them.
  14. 14 Marks
    Numerical: A superscalar processor executes 4 instructions/cycle. If 20% instructions are dependent, what is the maximum speedup?
