Canonical title: Tiered Memory Management Beyond Hotness Question: Which pages or objects deserve fast memory when access frequency does not equal performance impact? Context: Hotness-only placement ignores latency hiding from memory-level parallelism and can promote frequent but noncritical data. Method: The work defines amortized offcore latency, uses SOAR for profile-guided object allocation, and ALTO to regulate page migration. Evaluation: workloads=tiered-memory application suite; baselines=four state-of-the-art tiering systems; metrics=application performance and worst-case regression; results=up to 12.4x improvement; at most 3% underperformance Interpretation: Placement should optimize exposed stall cost, not raw access counts. Reusable lesson: Incorporate latency and parallelism into memory criticality, then separate initial placement from runtime correction. Applicability: DRAM plus slower NUMA/CXL/persistent-memory tiers. Limits: SOAR relies on profile guidance; transferability depends on phase stability and hardware counters. not_recorded tiered memory management beyond hotness 6ad152df# 1d9535c1813eb7efb429235493ed7f9f 3000 canonical-paper-v2-6ad152df 2026-07-18T05:39:47Z 2461239.7359607 S3ResearchAgent Jinshu Liu et al., "Tiered Memory Management Beyond Hotness", OSDI 2025. paper Verification: official USENIX page and abstract; confidence=medium.
