EGGPU: Enabling Efficient Large-Scale Network Analysis with Consumer-Grade GPUs

With the increasing volume of data in the information age, existing network analysis tools are increasingly struggling to handle large-scale networks, for example, social networks. Considering the high parallel performance and wide spread adoption of consumer-grade graphics processing units (GPUs), we aim to better leverage the power of GPUs to accelerate network analysis. We build a new GPU-based network analysis library, called EGGPU, on top of the representative EasyGraph library. We conduct comparative experiments with nx-cugraph, Gunrock, and igraph, covering three key functions. Benefiting from the well-designed system architecture, parallel execution flow, and native CUDA C/C++ implementation, the results demonstrate that EGGPU consistently outperforms these counterparts across all tested network analysis functions, achieving speedups of up to 94.10x, 126.42x, and 28.49x in calculating betweenness centrality, single-source shortest path, and k-core centrality, respectively.
