+description: "Run and measure a radiance GPTQ calibration tap on a disk-tiered BF16 rig — n-gram tier, step sized to the document, tap marker gates, and reading the real rate from /stats instead of the log."
+---
+
+# Running and measuring a radiance calibration tap
+
+A calibration tap (`RADIANCE_CALIB_DIR` + `RADIANCE_CALIB_TOKENS`) boots a BF16 reference container
+on the serving cards under `--weights-disk-tier` and prefills a corpus until the pooled token floor
+is reached, writing per-expert Grams for GPTQ. It is the one campaign phase whose cost is dominated
+by **disk read volume**, not by compute, and the shape that serves production is the wrong shape for
+it.
+
+## The four things that decide the tap's wall time
+
+1. **N-gram table tier.** On the BF16 payload the table is tens of GiB and `--ngram-placement ram`
+   PINS it. Beside a full host pool that leaves a few GiB of RAM and the boot dies at
+   `startup stopped: out of memory` while the same pool and slot count had already booted the
+   reference recording. Calib only needs the routed weights prefilled, so pass
+   `--ngram-placement disk` for calib and keep `ram` for the KL modes — their numbers are only
+   comparable at an identical shape.
+2. **Step ≥ document length.** A document cut into N steps re-streams each layer's routed expert
+   union N times from the container. With `--max-num-batched-tokens` below the document length the
+   tap runs several times slower than with one wide step, and the KV pool does not change at all
+   (`kv_tokens_total` is unaffected). This is legal for calib and NOT for a scoring boot: scoring
+   numbers are only comparable at one shape, so the step is calib's own knob.
+3. **KV pool, not slots.** When the pool holds barely one document, extra `--max-num-seqs` only
+   queue (and preempt) requests; raising slots does not raise throughput.
+4. **The token floor is pooled, not per round.** One corpus pass may be smaller than the floor, so a
+   round that seals no bytes is NORMAL — a driver that treats a flat round as failure aborts one
+   round early. Fail on a tap that *loses* bytes; let "never sealed" fail at max rounds.
+
+## Never push a tap that belongs to no rig
+
+A tap dir is a directory; production is also an endpoint on the same port. Without proof, a pusher
+will happily feed millions of tokens into whatever answers and record nothing.
+
+- The rig writes a marker into the tap dir at boot (`container=`, `image=`, `pid=`), retires it
+  when its boot exits non-zero, and the pusher refuses unless the marker exists, names the
+  container it targets, and that container is running.
+- The window script stops on a failed phase instead of falling through its health wait, and banks a
+  large reference artifact only when both phases exit 0 and the tap holds files.
+
+## Measuring the rate (do not read it off the log)
+
+The campaign log is `tee`'d and block-buffered, so its request count lags by minutes.
+
+```bash
+curl -s http://127.0.0.1:7770/stats | python3 -c 'import json,sys; d=json.load(sys.stdin); \
+  print({k: d[k] for k in ("uptime_s","prefill_tps","steps_prefill","total_requests","preemptions","kv_tokens_total")})'
+```
+
+`prefill_tps` is CUMULATIVE over uptime — `tokens ≈ prefill_tps × uptime_s`, so take two samples a
+couple of minutes apart and difference them. `steps_prefill / total_requests` proves whether a
+document is one step or many. Discard the first minutes after boot (warmup and the first requests
+are not the steady state).
+
+## Sizing the tap before paying for it
+
+Probe one 5-minute sample at the candidate step, compute the ratio against the inherited shape, and
+choose the floor from the measured rate — not from an earlier campaign's runtime on a different
+corpus and shape. Then set `RADIANCE_CALIB_TOKENS` (via the runner's env knob) and launch ONE run;
+if the probe already beat the bar, that probe run IS the real run and needs no restart.
+
+## Deliverables that make it unattended
+
+- a gated window script: boot → health with a hard timeout → push → stop → restore the service →
+  bank the reference artifact only on success;
+- a pusher that is marker-gated and progress-aware;
+- a ledger line recording the shape used and the target chosen, so the next session does not
+  re-derive it.

+description: "Measure a radiance rig's real prefill rate and prove whether the bottleneck is disk, CPU or shape — for calibration taps, KLD recording or score boots; use when a rate looks wrong, an ETA must be quoted, or someone asks about CPU allocation."
+---
+
+# Census a radiance rig's throughput without lying to yourself
+
+Ask three questions in order: what is the rate, what is the binding resource, and does the shape
+explain it. Every number below comes from a kernel or engine counter — never from a gauge.
+
+## 1. The rate: counters, never `prefill_tps`
+
+`/stats` on :7770 exposes `prefill_tps`, and it is a **rolling gauge**. Reading 69.5 → 149.1 across
+120 s and multiplying by `uptime_s` produced a bogus "320 tok/s / 10.4 h" verdict that had to be
+retracted (measured 2026-10-29). Derive the rate from counters over a ≥240 s window:
+
+```bash
+python3 - <<'PY'
+import json, time, urllib.request
+def stats(): return json.load(urllib.request.urlopen("http://127.0.0.1:7770/stats", timeout=10))
+a = stats(); t0 = time.time(); time.sleep(240); b = stats(); t1 = time.time(); dt = t1 - t0
+docs = b["total_requests"] - a["total_requests"]
+steps = b["steps_prefill"] - a["steps_prefill"]
+MEAN = 4238.0            # tokens/doc, from the corpus: total_tokens / documents
+print("docs %d in %.0fs -> %.0f tok/s | steps/doc %.2f" % (docs, dt, docs * MEAN / dt, steps / docs))
+PY
+```
+
+`steps/doc` is the read-amplification signal: a document cut into N prefill steps re-streams each
+layer's routed expert union N times when the weights are on the disk tier, so N > 1 is leaked time.
+
+## 2. The binding resource: diskstats and the idle/iowait split
+
+```bash
+# per-device read bandwidth (parent device, not the partition)
+awk '{print $3, $6*512}' /proc/diskstats | grep -E "^nvme"
+# host busy = total - idle - iowait (summing /proc/stat's first 8 fields WITHOUT subtracting is
+# the classic error: the sum already covers idle, so it reads ~800% on an 8-core box)
+```
+
+Then split CPU by process: sample `/proc/<pid>/stat` fields 14+15 (utimes + stimes) twice.
+
+Two hard readings that decide the argument:
+
+- `radiance` compute at ~0.26 cores while the disk delivers ~3.2 GB/s and `iowait` is ~29 % of the
+  box ⇒ **disk-bound**. More cores or a `--cpuset-cpus` pin cannot add bytes; pinning only caps it.
+- A container with `cpu_quota=0` and an empty `CpusetCpus` (check `podman inspect -f
+  '{{.HostConfig.CpuQuota}} {{.HostConfig.CpusetCpus}}'`) is already unrestricted — "allocate more
+  CPU" is a no-op, and "allocate 6 of 8" is a ceiling.
+
+Sanity relation: tok/s × (GiB streamed per document ÷ tokens per document) should match the measured
+device bandwidth. If it does not, the shape, not the hardware, is the story.
+
+## 3. The shape: what may legally be widened
+
+- `kldref` and `score` must keep production's `--max-num-batched-tokens` and `--max-num-seqs`: their
+  KL numbers are only comparable across boots at an identical shape (the audit law).
+- A **calibration tap** is exempt — its output is layer Hessians, nothing compares it. Give it a step
+  that covers a whole document (`Q38_CALIB_MNBT` ≥ the corpus window) and read `steps/doc`: on a
+  7,168-token corpus, 2,048 → 8,192 moved 2.5 → 1.00 steps/doc and 94 → 113 tok/s (**1.2×**, not the
+  4× the step-count ratio suggests — total bytes are unchanged, so do not promise more).
+- The KV pool, not the step, bounds concurrency: when `kv_tokens_total` ≈ one document, requests queue
+  and preempt; extra slots buy nothing.
+
+## Reporting
+
+Quote tok/s, steps/doc, device GB/s and the busy/iowait split together, plus the shape each number
+was taken at. A rate without its shape is not a measurement; a gauge without its window is not a rate.
