This work proposes a novel reconfigurable architecture for reducing the latency of JEDI-net, a Graph Neural Network (GNN) based algorithm for jet tagging in particle physics, which achieves state-of-the-art accuracy. Accelerating JEDI-net is challenging since it requires low latency to deploy the network for event selection at the CERN Large Hadron Collider. This paper proposes an outer-product based matrix multiplication approach customized for GNN-based JEDI-net, which increases data spatial locality and reduces design latency. It is further enhanced by code transformation with strength reduction which exploits sparsity patterns and binary adjacency matrices to increase hardware efficiency while reducing latency. In addition, a customizable template for this architecture has been designed and open-sourced, which enables the generation of low-latency FPGA designs with efficient resource utilization using high-level synthesis tools. Evaluation results show that our FPGA implementation is up to 9.5 times faster and consumes up to 6.5 times less power than a GPU implementation. Moreover, the throughput of our FPGA design is sufficiently high to enable deployment of JEDI-net in a sub-microsecond, real-time collider trigger system, enabling it to benefit from improved accuracy.
