__*Distributed Neighbor Expansion (Distributed NE)*__ : A scalable parallel and distributed graph partitioner for high-quality edge partitioning, which has several key features:

- __Low-memory and high-performance implementation__
- __Provide high-quality edge partitionins__
- __Scalable to trillion-edge graphs on 200+ machines__ (1 trillion = 1,000,000,000,000)
