The affinity_partitioner class is similar to the static_partitioner class, but it improves cache affinity by its choice of mapping subranges to worker threads. It can improve performance significantly when a loop is re-executed over the same data set, and the data fits in cache. Note that the same affinity_partitioner object must be used with subsequent iterations of a parallel loop that is executed over a particular data set, to benefit from data locality.
