Adaptive Aggregation on Chip Multiprocessors

Summary: On chip multiprocessors, hash aggregation is shaped by private vs shared structures and cache contention. We introduce an adaptive aggregation operator that samples input to pick the best strategy by run-length, locality, and accesses, with gains. (summarized by gpt-5-nano on Feb 09 2026)
