Abstract
A system and method for merging a plurality of sorted lists using multiple processors having access to a common memory in which N sorted lists which may exceed the capacity of the common memory are merged in a parallel environment. Sorted lists from a storage device are loaded into common memory and are divided into a number of tasks equal to the number of available processors. The records assigned to each task are separately sorted, and used to form a single sorted list. A multi-processing environment takes advantage of its organization during the creation of the tasks, as well as during the actual sorting of the tasks.
