  Graph embedding maps graph nodes to low-dimensional vectors, and is widely
adopted in machine learning tasks. The increasing availability of billion-edge
graphs underscores the importance of learning efficient and effective
embeddings on large graphs, such as link prediction on Twitter with over one
billion edges. Most existing graph embedding methods fall short of reaching
high data scalability. In this paper, we present a general-purpose,
distributed, information-centric random walk-based graph embedding framework,
DistGER, which can scale to embed billion-edge graphs. DistGER incrementally
computes information-centric random walks. It further leverages a
multi-proximity-aware, streaming, parallel graph partitioning strategy,
simultaneously achieving high local partition quality and excellent workload
balancing across machines. DistGER also improves the distributed Skip-Gram
learning model to generate node embeddings by optimizing the access locality,
CPU throughput, and synchronization efficiency. Experiments on real-world
graphs demonstrate that compared to state-of-the-art distributed graph
embedding frameworks, including KnightKing, DistDGL, and Pytorch-BigGraph,
DistGER exhibits 2.33x-129x acceleration, 45% reduction in cross-machines
communication, and > 10% effectiveness improvement in downstream tasks.
