Observations from Parallel Sorting Part I: the subtleties of tbb::parallel_reduce

In this series of postings, I discuss two common sorting algorithms, mergesort and quicksort, and highlight some of the interesting issues that arise when creating parallel implementations using TBB.  In all cases we’ll assume that, like STL’s std::sort, the input to the sort is a pair of RandomAccessIterators begin and end that denote the beginning and ending of the collection to be sorted, and a comparator object compare that provides an operator() for ordering two given elements.
