This library provides a framework to parallelize algorithms that follow a divide-and-conquer pattern. Its two main components are the skeletons parallel_recursion and dparallel_recursion. The first one parallelizes the required algorithm using multithreading within a single process. The second skeleton supports the parallelization across hybrid memory environments such as clusters of nodes with multi-core processors as well as multiple processes on top of the MPI standard.
