Gunrock is a CUDA library for graph-processing designed specifically for the GPU. It uses a high-level, bulk-synchronous, data-centric abstraction focused on operations on a vertex or edge frontier. Gunrock achieves a balance between performance and expressiveness by coupling high performance GPU computing primitives and optimization strategies with a high-level programming model that allows programmers to quickly develop new graph primitives with small code size and minimal GPU programming knowledge.
For more details, please visit our website, read Why Gunrock, our TOPC 2017 paper Gunrock: GPU Graph Analytics, look at our results, and find more details in our publications. See Release Notes to keep up with the our latest changes.
Gunrock is featured on NVIDIA's list of GPU Accelerated Libraries as the only external library for GPU graph analytics.

We are gradually adding summaries of our results to these web pages (please let us know if you would like other comparisons). These summaries also include a table of results along with links to the configuration and results of each individual run. We detail our methodology for our measurements here.
- Gunrock performance compared with other engines for graph analytics
- Setting parameters for direction-optimized BFS
- Gunrock results on different GPUs
- Gunrock BFS throughput as a function of frontier size
- Multi-GPU Gunrock Speedups and Multi-GPU Gunrock Scalability
- Multi-GPU Gunrock Partition Performance
- Comparison to Groute
For reproducibility, we maintain Gunrock configurations and results in our github gunrock/io repository.
We are happy to run experiments with other engines, particularly if those engines output results in our JSON format / a format that can be easily parsed into JSON format.

Thanks to the following developers who contributed code: The connected-component implementation was derived from code written by Jyothish Soman, Kothapalli Kishore, and P. J. Narayanan and described in their IPDPSW '10 paper A Fast GPU Algorithm for Graph Connectivity (DOI). The breadth-first search implementation and many of the utility functions in Gunrock are derived from the b40c library of Duane Merrill. The algorithm is described in his PPoPP '12 paper Scalable GPU Graph Traversal (DOI). Thanks to Erich Elsen and Vishal Vaidyanathan from Royal Caliber and the Onu Team for their discussion on library development and the dataset auto-generating code. Thanks to Adam McLaughlin for his technical discussion. Thanks to Oded Green for his technical discussion and an optimization in the CC primitive. Thanks to the Altair and Vega-lite teams in the Interactive Data Lab at the University of Washington for graphing help. We appreciate the technical assistance, advice, and machine access from many colleagues at NVIDIA: Chandra Cheij, Joe Eaton, Michael Garland, Mark Harris, Ujval Kapasi, David Luebke, Duane Merrill, Josh Patterson, Nikolai Sakharnykh, and Cliff Woolley.
