A system, method, and computer program product are provided for efficiently performing a scan operation. In use, an array of elements is traversed by utilizing a parallel processor architecture. Such parallel processor architecture includes a plurality of processors each capable of physically executing a predetermined number of threads in parallel. For efficiency purposes, the predetermined number of threads of at least one of the processors may be executed to perform a scan operation involving a number of the elements that is a function (e.g. multiple, etc.) of the predetermined number of threads.
