Efficiently Joining Large Relations on Multi-GPU Systems

Summary: Heterogeneous multi‑GPU sort‑merge join that leverages NVLink/NVSwitch P2P, handles out‑of‑core data, and combines GPU P2P partitioning, CPU multiway merge, and a hybrid CPU/GPU join strategy. Outperforms CPU/GPU baselines (up to 15.2x vs CPU SMJ, 5.5x vs radix, up to 8.7x vs non‑P2P multi‑GPU), scales with GPU count, and keeps overlapped copy/compute overhead low.
