HetExchange: Encapsulating heterogeneous CPU-GPU parallelism in JIT compiled engines
Summary: HetExchange extends the relational Exchange for heterogeneous CPU–GPU servers, combining CPU task-parallelism and GPU data-parallelism across non-coherent memory. JIT integration makes operators parallelism- and data-location-agnostic, delivering 2.8–6.4× gains over CPU- and GPU-only DBMSs. (summarized by gpt-5.6-luna on Jul 24 2026)
