iQCAR: A Demonstration of an Inter-Query Contention Analyzer for Cluster Computing Frameworks
Summary: Demonstrates iQCAR, a model of inter-query contention in clusters, using an iQC-Graph to attribute interference among concurrent queries. An interactive demo to identify top victims/sources, diagnose hotspots, and compare scheduler rules by predicting impact on later runs. (summarized by gpt-5-nano on Feb 09 2026)
