Symmetric multiprocessing (SMP) architectures are useful for situations where data must remain in memory during processing to achieve the desired performance level.

  • A.
    True
  • B.False

Answer: A

Correct answer: True

Because all the processors share one memory, a large data set can sit in memory once and be worked on by every processor without being copied. Where the data must stay resident to meet the performance target, that shared memory is exactly the property required - and it is also the source of the contention that limits how far the architecture scales.
