AI accelerator deep dive

Precision and DVFS policy must be co-designed with quality guardrails and thermal behavior.

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.

Handoff explanation

Inputs should include workload profile, model revision, compiler/runtime versions, and platform power mode.

Outputs must include actionable interpretation of Accuracy retention relative to baseline after quantization-aware training and deployment calibration., required artifacts (End-to-end quantization playbook covering training hooks, calibration procedure, and deployment validation checks.), owner, and validation scope.

The ideal handoff packet is reproducible: fixed seeds, explicit baseline, and rejected alternatives.
