제목 FlexMem: Adaptive Page Profiling and Migration for Tiered Memory
궁금했던 점 How can tiered memory adapt profiling and migration to workloads whose hot sets and phase behavior differ?
해본 것 FlexMem combines performance counters with hint faults, dynamically adjusts demotion volume, and tracks warm-page ranges.
당시 조건 Venue: USENIX ATC. Year: 2024.

Fixed sampling and promotion/demotion thresholds either miss hot pages or spend too much on profiling and movement.

Verification: full_text; confidence=high.

실제 결과 workloads=common memory-intensive benchmarks; baselines=Tiering-0.8; TPP; MEMTIS; metrics=application performance; profiling overhead; migration efficiency; results=32% average over Tiering-0.8; 23% over TPP; 27% over MEMTIS
왜 그랬는지 Profiling fidelity and migration aggressiveness should be controlled together from workload feedback.
다음에 기억할 것 Adapt both measurement cost and actuation strength, not just the placement threshold.
언제 맞는지 Linux heterogeneous/tiered-memory systems.

Limits: Tuning and gains depend on hardware counters, memory topology, migration costs, and workload phase length.

Verification: full_text; confidence=high. Canonical title: FlexMem: Adaptive Page Profiling and Migration for Tiered Memory Question: How can tiered memory adapt profiling and migration to workloads whose hot sets and phase behavior differ? Context: Fixed sampling and promotion/demotion thresholds either miss hot pages or spend too much on profiling and movement. Method: FlexMem combines performance counters with hint faults, dynamically adjusts demotion volume, and tracks warm-page ranges. Evaluation: workloads=common memory-intensive benchmarks; baselines=Tiering-0.8; TPP; MEMTIS; metrics=application performance; profiling overhead; migration efficiency; results=32% average over Tiering-0.8; 23% over TPP; 27% over MEMTIS Interpretation: Profiling fidelity and migration aggressiveness should be controlled together from workload feedback. Reusable lesson: Adapt both measurement cost and actuation strength, not just the placement threshold. Applicability: Linux heterogeneous/tiered-memory systems. Limits: Tuning and gains depend on hardware counters, memory topology, migration costs, and workload phase length.
