Improving Execution Efficiency of Just-in-time Compilation based Query Processing on GPUs
Summary: Shows that JIT GPU query engines are bottlenecked less by memory stalls than by control-flow divergence and resource contention. Pyper introduces cost-based Shuffle and Segment operators to restore parallelism, outperforming existing GPU engines on TPC-H/SSB. (summarized by gpt-5.6-luna on Jul 24 2026)
