FlashGraph is a general-purpose graph analysis framework that exposes vertex-centric programming interface for users to express varieties of graph algorithms. FlashGraph scales graph computation to large graphs by keeping the edges of a graph on SSDs and computation state in memory. With smart I/O scheduling, FlashGraph is able to achieve performance comparable to state-of-art in-memory graph analysis frameworks and significantly outperforms state-of-art distributed graph analysis frameworks while being able to scale to graphs with billions of vertices and hundreds of billions of edges.
