FGAQ: Accelerating Graph Analytical Queries Using FPGA

Field-programmable gate arrays (FPGAs) have significant advantages in parallelism and energy efficiency over CPUs and GPUs and are widely deployed by many enterprises and cloud server providers nowadays. In this paper, we demonstrate \(\textsf{FGAQ}\) , an FPGA-based system for accelerating graph queries on massive graphs. \(\textsf{FGAQ}\) supports the two most fundamental types of graph queries, namely subgraph and path queries, and features 1) a CPU-FPGA co-designed framework, 2) a fully pipelined FPGA execution, and 3) reduced data transfer from FPGA’s external memory. \(\textsf{FGAQ}\) provides a user-friendly interface and significantly improved performance. Performance evaluation shows that \(\textsf{FGAQ}\) outperforms the most popular graph database, Neo4j, by up to three orders of magnitude.
