Parallel Processing

5. The first part of the global sum example in which each core adds its assigned computed values, is an example of data-parallelism, while the second part of the global sum in which cores send their partial sums to the master core to add, is an example of task-parallelism. What about the second part of the tree-structured global sum? Is this an example of data- or task-parallelism? Justify your answer (explain the reason)
