Abstract
A first quicksort is performed in parallel across pairs of partitions of a dataset assigned to respective ones of available processors, including swapping elements of a first partition of a given one of the pairs that are larger than a pivot with elements of a second partition of the given pair that are smaller than the pivot. A second quicksort is performed in parallel across those partitions having elements left unsorted by the first quicksort, and first misplaced elements from a first side of the dataset corresponding to the first partition are swapped with second misplaced elements from a second side of the dataset corresponding to the second partition to produce a first dataset having elements equal to or lower than the pivot and a second dataset having elements equal to or higher than the pivot.
