  • Processors apply same operation to each element of data structure.
    • Data distribution can be specified by the programmer.
    • Example: HPF

• Task Parallelism

  • Processors have separate tasks and can operate on different parts of the data.
  • Its all in the problem decomposition.
  • Can use multi-process or multi-thread; shared-memory or distributed-memory.
