1. A method with an information processing system for accelerated radix sort processing of an array of data elements, the method comprising: storing an array of data elements in a first memory, the array having a head end and a tail end; radix sort processing, with a head processor, data elements starting at the head end of the array and progressively advancing radix sort processing data elements toward the tail end of the array; and radix sort processing, with a tail processor, data elements starting at the tail end of the array and progressively advancing radix sort processing data elements toward the head end of the array, the tail processor radix sort processing data elements in the array contemporaneously with the head processor radix sort processing data elements in the array.
