NeutronOrch: Rethinking Sample-based GNN Training under CPU-GPU Heterogeneous Environments

Summary: Diagnoses suboptimal CPU–GPU orchestration in sample-based GNN training and introduces layer-decoupled execution that pushes bottom-layer training to CPU to shrink GPU compute and memory footprint. NeutronOrch offloads only frequently accessed vertices with bounded-staleness embedding reuse and a fine-grained pipeline, achieving up to 11.51× speedup over prior systems.
