igneum-labs 5c808b89e0 Ember Tune: every card tuned for MH per watt out of the box, the fleet prior per card model in the signed manifest, the console and /miners priors table
the project lead, 5 October 2026, 22:45 BST: "make sure we have ember tuning every single card for efficiency out of the box, the
more data = the better the tune, make an awesome system." Built on lever 3 (docs/plans/miner-eff.md), lever 2's signed
tuning section (docs/design/miner-tuning.md), the AMD telemetry helper (423936b, its --tune/--set-gmax/--set-plimit/
--reset contract) and the Power control switch (057f0ec). Design, data flow, tiers and the privacy line:
docs/plans/ember-tune.md.

- src/ember.rs (new): two knobs per card (power limit %, core clock cap MHz; memory clock never touched), the full plan
  (power ladder 100..50%, then the clock ladder 90..60% at the chosen power), the confirm plan (the fleet prior and one
  neighbour), the baseline plan (measure only), the marks (faulted, hot, memory_clock_dropped, unapplied, no_readings),
  the choice (best MH/W within 1% of the top rate, then rate, then draw), the fleet record (a hash of the install id,
  no address), the prior lookup and the kill switch (tuning.ember), the state machine on a fake clock. 9 unit tests.
- engine.rs: tick_sweep schedules every NVIDIA, AMD and Apple card (120 s steady, 600 s to the boundary, no job hold,
  no pause, weekly, again after a driver major or program-class change, never under the manifest kill switch); the
  probe (nvidia-smi clocks.max.gr + driver_version and the direct/helper mode; igneum-gpu-telemetry --tune for AMD);
  tune_apply (nvidia-smi -pl / -lgc 0,<MHz> / -rgc directly or through the helper; the AMD helper per request);
  Cmd::TuneProbe, Cmd::TuneSet; faults from rejected and mismatched hashes mark the step; the TUNE lines and the TUNE
  {json} record, uploaded with the log; the Tuned line on the card state. The NVIDIA helper starts only with Power
  control on: the --sweep job never counts as permission (no prompt on a PC with nobody there).
- sweep.rs: the helper protocol gains lgc/rgc (clock cap and reset) and resets the clocks after 20 idle minutes.
- state.rs, config.rs: the tune fields (clock cap, driver, class, source, the Tuned line); the nvidia-smi telemetry
  query carries clocks.gr and clocks.mem; the AMD sample line's plimit_pct and gmax_mhz are parsed.
- ui: "Tuned: X MH/s at Y W (Z MH/W)" with the point, the source and when; measure-only cards say why; the Ember Tune
  switch; tune-line.test.mjs.
- relay/lib/ember.mjs + relay/test/ember.test.mjs: the aggregation per (card model | driver major | program class):
  median point, MH/W, spread, samples, machines; five samples converge, an outlier does not move the median, baselines
  make no prior, de-duplication, the manifest merge keeps lever 2's cards. api/console.mjs fn=tuning and
  tools/console.mjs tuning; tools/tuning.mjs --priors [--write tuning.json] [--site] [--tuning-off].
- site: the fleet priors table on /miners (site/miner-priors.json), the lever text.
- relay/playbooks/ember-tune-pc1.ps1: the PC 1 run (second engine with --sweep from a scratch copy of the install).

Measured tonight: see the bench log entry that follows the PC 1 run. The 9070 XT left PC 1's bus at 20:40 UTC and the
5090 needs the administrator prompt the project lead cannot answer asleep, so tonight's PC 1 run is the baseline plan on the 5090
through the whole pipeline; the two-knob tune on both cards is owed.

<h2 id="how">How a row gets here</h2>
<p>Every row names the engineering log entry or the job it came from. "Measured by the team" means our own hardware and our own log. "Reported by the fleet" means a machine we do not own, read from the status lines its miner uploads.</p>
<p>MH per watt needs the card's power draw during the run. The app reads it on NVIDIA cards through the driver. Rows get the figure when a run records it.</p>
<p>There is no other Igneum miner to compare with yet, so this table compares cards, not miners. The app that produces these rows: <a href="/miner">the miner page</a>.</p>
<p>Rows: 6. Source file: <code>site/miner-bench.json</code> in the repository.</p>
<h2 id="priors">Fleet tuning priors</h2>
<p>Ember Tune runs on every card the app mines with: the power limit and the core clock are stepped on the live program and the card keeps the point with the best MH per watt within 1% of its top rate. Every finished tune is reported back without anything that identifies the owner, and the fleet's median point per card model, driver major and program class comes back down inside the signed update manifest as the starting point for the next card of that model. A model needs 5 reports before its prior is used.</p>
<p>No tune reports yet. The first rows appear once five machines with the same card model have reported.</p>
<p>Rows: 0. Source file: <code>site/miner-priors.json</code> in the repository, written from the fleet records by <code>tools/tuning.mjs --priors --site</code>.</p></article>
