As graphs become bigger, the need to efficiently partition them becomes more pressing. Most graph partitioning algorithms subdivide the vertex set into partitions of similar size, trying to keep the number of cut edges as small as possible. An alternative approach divides the edge set, with the goal of obtaining more balanced partitions in presence of high-degree nodes, such as hubs in real world networks, that can be split between distinct partitions. We introduce dfep, a distributed edge

After each iteration, smaller partitions receive an higher amount of currency to help them recover lost ground and reach a similar size to the other partitions. Simulation experiments show that dfep is efficient and obtains consistently balanced partitions. Implementations on both Hadoop and Spark show the scalability of our approach.
