Cycle-Detection: A Parallel Algorithm for Cycle Detection in Planar Partitioned Digraphs

This package provides an MPI implementation of a new, parallel algorithm for detecting cycles in partitioned, planar directed graphs that is both scalable in the graph and machine size, and performs well in practice. As an example, on a p = 64 processor cluster, we have solved an extremely large and difficult input problem with n = 228 vertices in less than five minutes.
