Sample PDC questions


Under what circumstances would you use Pool to generate a pool of concurrent processes (as
we did in parallelSumPrimes) versus when you might use Process to instantiate each process
independently?



  Many image processing algorithms are parallelizable. Consider the quantization code we
  wrote, which reduces the number of bits used to represent each channel of color. Describe
  in detail how you might parallelize this image operation in Python (as in, what parallel
  processes you would instantiate, what parameters those processes would receive, etc.).

  Describe the use of Process/Pipe versus Pool/map in Python. How did we use the
  two paradigms for the algorithms we discussed (in detail)?
