Rethinking MIMD-SIMD Interplay for Analytical Query Processing in In-Memory Database Engines

Summary: Shows recent CPU SIMD advances relax linear-access constraints, making non-linear memory access SIMD-friendly. Presents a unified MIMD+SIMD parallelization for in-memory analytical engines to exploit both paradigms for lower latency and higher throughput. (summarized by gpt-5-mini on Feb 09 2026)
