The first part of the global sum examplewhen each core adds its assigned computed valuesis usually considered to be an example of data-parallelism, while the second part of the first global sumwhen the cores send their partial sums to the master core, which adds themcould be considered to be an example of task-parallelism. What about the second part of the second global sumwhen the cores use a tree structure to add their partial sums? Is this an example of data- or task-parallelism? Why?
