The included code and white paper provides details for the implementation of a thread-safe data structure that creates and manages multiple ordered lists as a single data structure. Lists within the structure are indexed starting at 0 and proceed up to one less than the number of lists created. A set of API functions to interact with the multi-list structure are defined as outlined in the data structure description. A problem to “rank” instances of integers within a multi-list structure is used to test the data structure implementation. Parallelism is implemented using Pthreads.
