Description

Optimizing the inference of Graph Neural Networks (GNNs) for track finding is crucial for enhancing the computing performance of particle collision event reconstruction. Track finding involves identifying and reconstructing the paths of particles from complex, noisy detector data. By leveraging GNNs, we can model the relationships between detector hits as a graph, where nodes represent hits and edges represent potential connections between them. To speed up the inference of these GNN models, it is important to reduce computational overhead, improve model architecture, and exploit hardware accelerators such as GPUs. Techniques like quantization and pruning can be employed to minimize model size and inference time without sacrificing accuracy.
