GNN Training

Training Graph Neural Networks (GNNs) efficiently on massive graphs is a critical challenge driving current research. Efforts focus on optimizing various stages of the training process, including subgraph sampling strategies, efficient data I/O and memory management (especially leveraging CPU-GPU heterogeneous environments and persistent memory), and communication reduction techniques for distributed training. These advancements aim to improve both the speed and scalability of GNN training, enabling the application of these powerful models to increasingly larger and more complex datasets in diverse fields like recommendation systems and knowledge graph reasoning.
