Metrics and artifacts to collect

• precision-mode mix

• perf-per-watt trend

• thermal clamp frequency

• quality regression monitor

Mini case study

Switching to lower precision improved nominal throughput, but thermal clamp cycles reduced sustained gains.

Debug branches

• Validate quality guardrails by slice

• Correlate thermal events to latency tails

• Audit precision fallback behavior

Senior review question

Ask: which first-principles bottleneck class explains the symptom, and what artifact proves it reproducibly?

Key takeaways

• Tie every accelerator claim to a reproducible workload slice and one primary metric trend.

• Prefer bounded fixes with clear owner and rollback boundary over broad tuning bundles.

Common pitfalls

• Optimizing synthetic kernels without production-shape validation.

• Reading average latency while ignoring p95 and p99 behavior.

• Declaring sparse or precision wins without fallback and quality evidence.

Principal accelerator review addendum

Quantization-Aware Design Across Model and Hardware should be framed as a full-system behavior, not an isolated kernel trick. Production outcomes are set by model shape mix, compiler choices, runtime queueing policy, memory hierarchy limits, and silicon delivery margins.

Quantization-aware design aligns model training, compiler transforms, and hardware execution paths so low-precision deployment behaves predictably. During training or fine-tuning, fake-quant operators and per-channel scaling expose quantization effects early, reducing surprise regressions at inference. On hardware, calibration data selection, zero-point handling, and outlier treatment determine whether throughput gains hold without violating quality targets. Effective programs treat quantization as a full-stack co-design activity, not a last-stage conversion script. A useful explanation always ties observed symptom to a repeatable path where useful work was blocked, delayed, or diluted by overhead.

Use Accuracy retention relative to baseline after quantization-aware training and deployment calibration. as an alarm, then anchor action using hard evidence such as End-to-end quantization playbook covering training hooks, calibration procedure, and deployment validation checks..

Precision policy is a system-level contract between quality, latency, and thermal limits. Senior reviews expect a chain of proof: workload intent -> mapping -> hardware behavior -> product impact.

Use this addendum to force explicit owner assignment, bounded fixes, and reproducible evidence before declaring closure.
