Build a multi-page benchmark report PDF -- scatter panels + per-concurrency
heatmap tables -- from inference benchmark sweep output. Mirrors the
GLM-5.1 reference layout:
Steady-state window: the report only renders what the sweep measured. A throughput
sweep cell needs num_prompts >= 2*c or its high-c throughput is undercounted
~1.6-1.8x (ramp/drain-dominated window, docs/METHODOLOGY.md trap 4). The
import_roofline_sweep importer flags steady_window_undercount + WARNs on any cell
< 2c - heed it before publishing the report.
Page 1: 5 rows (one per max_num_batched_tokens in {1024, 2048, 4096,
8192, 16384}) x 2 columns of scatter panes -- left=TTFT vs request
throughput, right=tok/s/user vs tok/s/GPU. Inline-labels selected
profiling concurrencies (default {1, 8, 32}). Color encodes (hardware,
TP). Circle marker = EP, X marker = TP. Hollow markers indicate MTP.
Page 2: 3 rows (C in {8, 16, 32}) x 2 columns of heatmap tables
showing output tok/s/GPU and TTFT avg (ms) for every (variant, mbt)
combo, with gray cells for missing / failed / partial measurements.
The renderer is workload-agnostic. It ingests any
AtlasCell-shaped JSONL.
Backends (vllm-sweep + AIPerf) normalize into the same schema.
When to use
Comparing inference performance across multiple hardware generations
(e.g. H100 FP8 vs B200 NVFP4 vs GB300 NVFP4) for the same model.
Comparing parallelism strategies (TP vs EP) and speculative-decoding
variants (MTP on / off) on a single deployment.
Re-rendering a stakeholder-grade report from previously captured
benchmark data without re-running the cluster sweep.
Producing a release-day PDF for a new model variant before promoting it
to staging / prod.
Do not use this skill for:
Single-deployment, single-concurrency snapshot benchmarks -- the
upstream perf-bench skill is the
right tool. Use this skill once you have multiple atlas cells to
compare side-by-side.
Training-benchmark reports (step-time / MFU) -- out of scope for this
plugin.
profile-and-optimize bundled MCP server installed (the standard bash ~/.claude/plugins/cache/profile-and-optimize-plugins/profile-and-optimize/<ver>/server/install.sh
or, from a repo checkout, bash plugins/profile-and-optimize/server/install.sh).
The perftunereport console script is installed into the same venv as
profile-and-optimize-mcp.
matplotlib>=3.8 + pandas>=2.0 in the profile-and-optimize venv. Install
the optional extra: .venv/bin/pip install -e '.[perf_tune_report]'.
For cell_run only: live cluster access (kubectl context +
namespace + bench pod) AND the same prerequisites as the upstream
inference-perf-bench skill
(HF_TOKEN, replay-playback dataset access).
No cluster needed for campaign_init, atlas_aggregate,
report_render, or report_smoke -- those operate on already-captured
data or the bundled synthetic fixture.
Workflow
Phase A: smoke-render the layout (no cluster, ~2 seconds)
Always do this first when introducing a new operator to the skill. It
proves the renderer is healthy and lets the operator see the output
shape without committing benchmark time.
The bundled synthetic fixture mirrors the GLM-5.1 PDF coverage exactly:
40 atlas cells, 38 full sweeps, 1 partial, 1 failed, 232 plot-ready
points, 20 evicted MTP context cells.
Phase B: scaffold the campaign
Author a campaign YAML under
configs/campaigns/<slug>.yaml (or any
operator-chosen location). Each cell entry must include cell_id,
model, hardware, quant, tensor_parallel, parallel_strategy,
mtp, max_num_batched_tokens, concurrencies, plus backend-specific
extras under vllm_sweep: and / or aiperf:.
This scaffolds ./campaigns/<UTC-ts>-<slug>/
with SOURCE.md, summary.md, frozen config.yaml, and empty
cells/ + commands/ subdirs. Returns the campaign dir in the JSON
envelope.
Phase C: run each cell
For each cell in the campaign config, drive cell_run with the
operator-chosen backend. This verb is ack-gated (safety=submits_jobs)
-- the cockpit requires the explicit
i_understand_this_submits_jobs=true parameter (or the CLI flag
--i-understand-this-submits-jobs) before any actual benchmark runs.
--dry-run lets you see the generated shell commands without
consuming cluster time.
Each cell writes its raw backend output under
<campaign>/cells/<cell-id>/raw/ and a normalized
<campaign>/cells/<cell-id>/normalized.json consumed by the next phase.
Cell status.txt is set to one of full / partial / failed based
on whether all requested concurrencies completed.
For multi-cell campaigns, loop the operator through each cell -- the
sweeps are long-running and benefit from explicit human consent per
cell (e.g. checking cluster capacity before each launch).
Unions every cell's normalized.json into one
<campaign>/atlas.jsonl and returns the Coverage summary block that
will appear on page 1 of the rendered PDF (e.g.
"Coverage: 40 atlas cells | 38 full sweeps | 1 partial sweeps | 1 failed cells | 232 plot-ready concurrency points").
Phase D1: TPM supported across hardware types (pricing rollup)
After aggregation, roll the atlas into a per-hardware tokens-per-minute (TPM)
capacity table for pricing / capacity discussions. This is a pure
post-processing step on already-measured data (no cluster runs).
# peak-capacity only:
perftunereport tpm_summary --campaign <slug>
# add a latency-SLA-bounded operating point (the customer-commitment number):
perftunereport tpm_summary --campaign <slug> --ttft-sla-ms 500 --tpot-sla-ms 50
Writes tpm_summary.{json,csv,md} to the campaign dir. For each
(model, hardware, quant, TP, strategy, MTP) group it reports a peak point
(max output tok/s/GPU -- warm sweep best-case) and, when --ttft-sla-ms /
--tpot-sla-ms are supplied, an sla point (highest tok/s/GPU meeting the
thresholds), each at per-GPU / per-replica (=TP GPUs) / per-node
(--gpus-per-node, default 8) bases, for both output-only and total
(input+output) TPM. Total-TPM is n/a for backends that emit no total-token
line. report_render also draws a peak-only "TPM supported across hardware
types" PDF page, and publish_to_lake lands a tpm_v1 table.
Report every TPM number with the warm/cold + ISL/OSL caveat the summary header
carries (per server/AGENTS.md "Benchmark methodology hygiene"): peak is a
warm best-case, the SLA point is the customer-commitment number.
Defaults: the SLA point + cost columns populate for EVERY
campaign without a config block -- discover_tpm_config falls back to a default
SLA (TTFT<=2000ms / TPOT<=50ms / gpus_per_node=8) and a default cost table
(representative public on-demand list rates per GPU: H100 $6.16 / H200 $6.31 /
B200 $8.60. GB300 unset). Declare a tpm:/cost:
block in the campaign config.yaml only to override (per field. Cost is overlaid).
report_render and publish_to_lake read it via discover_tpm_config, so all
three surfaces emit the same peak + sla points. The SLA point is still left unset
(not invented) for a group whose rows lack a decode metric (TPOT/ITL) at/under
the SLA -- a throughput-only bench has no decode metric to derive an SLA point
from, so re-run the bench with decode capture if SLA-TPM is needed.
Cost + analysis carry-through. The cost: block (usd_per_gpu_hour: { B200: 4.50, ... })
overrides/extends the default cost table behind the $/1M tok PDF column and the
cost_v1 economics/TCO lake table ($/1M output|total, plus tokens_per_watt +
power_watts_per_gpu when DCGM power is captured -- a cost: block cannot
synthesize tokens-per-watt). Default rates: H100/H200/B200 = representative public
list rates, GB300 = $12.00/GPU-hr ESTIMATE (no public list rate). To
derive tokens_per_watt the cell's DCGM power capture must record BOTH the bench
window AND the node (per-node DCGM_FI_DEV_POWER_USAGE). A window-only artifact
cannot be re-queried later. The atlas
also carries per-cell mean_input_tokens/mean_output_tokens (ISL/OSL, derived
from the bench Total input/generated tokens lines -> tpm_v1.mean_isl/mean_osl),
cache_mode (declared via import_perf_bench --cache-mode warm|cold), and
prefix_cache_hit_rate (from the bundle metadata). For tokens_per_watt, add
power_watts_per_gpu to the cell's dcgm_frozen_v1 YAML before dcgm_correlate.
Phase D2: byte-ground every cell to raise sol_rigor (recommended, not a gate)
DCGM byte-grounding raises a campaign's sol_rigor from L1 (zymtrace proxy)
to L3 (byte-grounded) - it is recorded, not gated (the
always-publish policy: a dcgm_grounded=false campaign still publishes, with
the gap visible on the campaign_v1 row). For each plot-ready cell, produce a
dcgm_correlation.json (renderer pages 6 + 6b) via the
inference-dcgm-correlate
skill (the live Prometheus MCP path) OR the offline CLI verb against a frozen
DCGM snapshot:
Capture DCGM (SM/DRAM/tensor/GR + NVLINK bytes) concurrently with each cell's
bench window so the means are real (see the experiment-isolation rule). A run
that skips it publishes at sol_rigor=L1 (dcgm_grounded=false) - valid and
comparable, just less tight. Prefer L3/L4 when DCGM/ncu are available.
The phase-separated roofline + per-(c,ISL) DCGM utilization (the "what
concurrency maxes the TFLOPs" + "is decode >=75% HBM bandwidth" questions, always
wanted). Capture with the gated *-deploy/profiling/roofline-sweep.sh (a
decode-concurrency sweep + a prefill-ISL sweep, each with per-cell in-pod
dcgmi dmon PROF - SM/tensor/DRAM/NVLINK), then ingest:
This writes cells/<id>-decode + <id>-prefill rows (per-(c,ISL) DCGM +
analytical roofline coords in extra -> atlas_v1.extra_json + the roofline_v1
lake table) + a cells/<id>-decode/roofline_sweep.json (carrying the embedded
analytical ModelShape) the renderer turns into page 7. Page 7 sets
sol_complete + dcgm_grounded + sol_rigor=L3. The per-(c,ISL) in-pod dcgmi
data is what the workload-level dcgm_correlate window-mean (Phase D2) cannot
produce. Import multiple configs (TP2/TP4/TP8, fp8-KV vs NVFP4-KV, baseline vs
optimized, vLLM vs SGLang, ...) into one campaign and page 7 overlays them.
Methodology (server/tools/perf_tune_report/ROOFLINE-METHODOLOGY.md): page-7
panel A plots x = analytical arithmetic intensity (FLOP/byte) (from the model's
config.json via roofline_math.py) and y = flop_per_token x measured tok/s / n_gpus against PER-GPU ceilings, so a decode point's vertical gap below the
memory diagonal IS its HBM utilization. Panel B (Q2) plots BOTH the DCGM
DRAM_ACTIVE duty-cycle proxy AND the byte-grounded delivered-HBM-BW % (honestly
labeled) + the 75% line. For a model not in the built-in registry, pass
--model-config <config.json> (or let roofline-sweep.sh capture the in-pod
model_config.json) so the analytical axis engages instead of the DCGM-proxy
fallback. Page 7 is now a strict-publish gate: a throughput/mixed serving
campaign with plot-ready points but no page 7 is REFUSED under publish_to_lake --strict (the default, --no-strict records the gap). The rendered PDF also
carries a "Source under test" page (vLLM/SGLang commit + delivery + infr patch
GitHub URL) from the bundle's experiment_provenance_v1 block + source-registry.yaml.
The campaign's recorded delivery is the code-under-test identity: a number
from this campaign may be cited as evidence only for THAT delivery, never cross-tier (an
overlay/offline-prepped run is not evidence for an infr-patch, even if the kernels match).
Phase D4: champion selection (page 8) - the production pick
The "what do we ship" synthesis. When the campaign holds a baseline + variant
arms (e.g. a cross-engine A/B imported via perf_tune_report_import_variant_ab from a
run-variant-ab.sh bundle: one engine-tagged vllm-sweep / sglang-sweep cell
per arm), champion_select ranks the baseline + top-X CROSS-ENGINE under the
focus metric + a TPOT SLO, summarizes each across the 4-layer SoL ladder, overlays
their rooflines, and emits the production recommendation:
It writes CHAMPION.md + champion_select.json (the artifact page 8
consumes -- a baseline-vs-top-X table with per-variant sol_rigor + HBM/tensor/SM%,
the overlaid roofline, and a RECOMMENDED-FOR-PRODUCTION banner) and, on publish,
the champion_v1 per-variant lake table + campaign_v1.recommended_cell. The
recommendation is DRAFT unless the champion passes the variance (--same-node
--trials>=3), multi-workload (--workloads-present covers the canonical
suite), and accuracy (--accuracy-gate pass) gates AND is L3 byte-grounded --
then it is a VERDICT. This is the deliverable that makes the prod choice
obvious. Run it before Phase E so page 8 lands in the PDF.
report_render always renders + records sol_complete / focus / sol_rigor
(it never refuses), publish_to_lake --strict is the opt-in gate if you want
publish to refuse a dcgm_grounded=false or otherwise incomplete campaign.
Default output path is <campaign>/report.pdf. Override with --out.
The renderer embeds UTC provenance into the PDF (CreationDate/ModDate
metadata + Keywords + a page-1 footer carrying campaign=<run-id>,
rendered=<...Z>, and the bench-capture window). All of these are UTC.
The PDF's OS file mtime is local wall-clock and is NOT authoritative --
on a UTC-7 workstation a render at 22:41 local reads a calendar day
behind its YYYYMMDDTHHMMSSZ run-id. Cite the run-id or the embedded
rendered=<...Z> stamp, never the mtime.
Phase F: share or archive
A campaign directory is fully self-contained
(SOURCE.md + frozen config.yaml + cells/ + atlas.jsonl +
report.pdf + per-shell commands/ capture). Share via
tar czf <slug>.tar.gz <campaign>/ to any teammate who has profile-and-optimize
installed.
Ack-gating behavior
cell_run is the only ack-gated verb (safety=submits_jobs). The
cockpit will:
Refuse the call if i_understand_this_submits_jobs is not set to
true.
Print a FATAL message naming the missing ack field and suggesting
--dry-run as the safe alternative.
Exit with code 2 (non-zero) so the cockpit treats it as a refusal,
not a silent skip.
All other verbs (campaign_init, atlas_aggregate, report_render,
report_smoke) write only to local disk under
./campaigns/<slug>/ (operator-relocatable via
PERFREPORT_CAMPAIGNS_DIR) and are not ack-gated.
Campaign-storage location
The default campaigns root is
./campaigns/ -- a local-only directory that holds campaign
artifacts. It is
gitignored so per-campaign output never accidentally
escapes the workstation. Source code for the renderer / runners /
schema lives in this plugin (server/tools/perf_tune_report/),
preserving profile_and_optimize's
single-clone-self-contained invariant.
Override the campaigns root via the PERFREPORT_CAMPAIGNS_DIR env var
or the --campaigns-dir CLI flag if you want campaigns to land
elsewhere (e.g. on a shared filesystem).
Full-context reporting (no bare numbers)
Per the methodology canon "Every performance number carries its full context (no bare numbers)"
(docs/METHODOLOGY.md): every number this
skill emits MUST carry its full measurement-context descriptor, and every comparison MUST be
matched on it. A bare tok/s / TPOT / BW / %SoL / speedup is a defect - it cannot set a
default, ship a config, or appear in a report.
Grounding:%SoL (+ ceiling key from configs/sol-ceilings.yaml - never inline a peak), sol_rigor (L1-L4), trials n (mean±std), same-node, baseline named.
Per-number exact shape (no smoothing): when reporting more than one number, keep EACH with its own exact shape (ISL/OSL, concurrency, dataset, regime) - never normalize a set to one uniform descriptor that hides per-point variation (e.g. c=1 @ ISL1024/OSL256 + c=64 @ ISL4096/OSL512, NOT one shared "random").
The rendered PDF carries up to four pages, the last of which is the
Speed-of-Light Roofline page. It draws automatically when:
The campaign has at least one valid cells/*/kernels.json (page 3
precondition. Zymtrace per-category data). A zymtrace L1 empty-now right after
the window is ClickHouse ingest lag, not absence - poll and requery
after the flush (see
server/docs/zymtrace-query-hygiene.md).
The renderer finds configs/sol-ceilings.yaml on the
ancestor path (or SOL_CEILINGS_YAML=/path env var override).
The atlas's hardware field maps to a key in the YAML (B200 →
b200_sm100, GB300 → gb300_nvl72, H100 → h100_sxm).
When ANY of the three is absent the page is not silently skipped.
The omission is recorded in report_status.json, surfaced on a
loud "Report completeness" page in the PDF (with the exact reason + how to
populate it), printed as a WARNING: on stderr, and returned in the
report_render JSON render_status block (sol_complete, focus,
sol_rigor, omitted_pages). sol_complete=true when ANY SoL page (4 zymtrace
/ 5 ncu / 6 DCGM) renders, sol_rigor records the highest level present.
Publish lands the row regardless (always-publish policy). Pass
publish_to_lake --strict only when you want a missing roofline or 0
throughput-scatter points (non-latency focus) to be a hard refusal. When the
YAML is found but malformed the renderer still raises SoLCeilingsMalformed
and aborts - same no-silent-degradation contract as KernelsJsonMalformed.
Per server/AGENTS.md "Speed-of-light framing", every campaign
SHOULD also carry a <campaign>/sol-summary.md doc with the
workload-level HBM-roofline calc and a link to the relevant grounding
doc. The SoL summary
is operator-written today. The page-4 visualisation is the auto-rendered
companion.
Asset validation (review + FAIL LOUD)
The report PDF this skill renders (report_render -> report.pdf: scatter / heatmap / roofline /
champion pages) is a DELIVERABLE held to server/AGENTS.md "Validate every generated asset"
(docs/METHODOLOGY.md): the renderer FAILS LOUDLY on missing/bad
data (SoLCeilingsMalformed / KernelsJsonMalformed raises, the degenerate-PDF guard that raises on
a <10KB report, and the methodology_problems--strict gate that refuses an incomplete/unknown
descriptor), and the agent REVIEWS the rendered PDF -- opens it, confirms every panel is accurate
(numbers + identities + matched comparisons trace to the campaign. Curves physically plausible,
failed/partial cells shown as such. Nothing mislabeled) -- and rebuilds it if wrong. Never ship a
broken/confusing report with a caveat.
Next lever / BREAKTHROUGH (Grind Mandate)
If this skill emits a measured result, its output MUST end by naming the next perf lever,
its expected unlock (direction + rough magnitude), and the gate that proves/refutes it,
per "The Grind Mandate" (server/AGENTS.md + docs/METHODOLOGY.md). A
measured win is the new floor, not the finish -- so do everything we can to find the next
BREAKTHROUGH: the highest-EV unlock toward Speed-of-Light (a new champion / kernel / router /
quant / parallelism / spec-decode win, or an unblocked stack), not just the next micro-lever.
Rank the candidate breakthrough levers by value x cost (the GRIND FRONTIER, perftunereport value_view), pursue the top, bank the rest with evidence. Record WHY a refuted lever loses,
update the standing frontier in the active bundle's HANDOFF.md. Never conclude
"exhausted/optimal/done" without an explicit next-lever frontier (an empty frontier AND a
documented SoL wall only). Delete this section ONLY if the skill produces no measurements.
Verdict rigor (DRAFT vs VERDICT)
Per server/AGENTS.md "Verdict rigor: DRAFT vs VERDICT", set the campaign's
verdict_tier honestly. Default draft. Set verdict only for a decision-grade
campaign that is variance-controlled (same-node, >=3 trials, mean +/- std),
metric-isolated (median TPOT/ITL for decode-latency claims), against a
production-representative baseline, and (for which-kernel claims) backed by nsys/ncu
per-kernel data. Under the always-publish policy a verdict-tier campaign
missing this provenance is auto-downgraded to draft and still lands (the
honest tier is recorded on campaign_v1). Pass publish_to_lake --strict if you
want the unsupported verdict claim to refuse instead.
Experiment isolation & traceability (mandatory)
This pipeline is the canonical "results -> rooflines -> perf-lake" path the
server/AGENTS.md "Experiment Isolation & Traceability" rule
(and docs/METHODOLOGY.md) requires every measurement
experiment to use:
Campaign id = experiment-id (the evidence-bundle run-id), so the
published campaign=<id> rows in atlas_v1 / campaign_v1 join back to the
cluster objects (label experiment=<id-slug>) and the evidence bundle.
cell_run cells that submit cluster workloads MUST use experiment-unique
serve names + the experiment=<id-slug> label and MUST NOT reuse
standing/platform/migration names (forbidden list in the server/AGENTS.md rule).
Cluster-scoped PV names are global. A collision silently breaks another
owner's PVC binding.
publish_to_lake is mandatory, not optional - a campaign is "done"
once the atlas + campaign rows are written AND report.pdf contains a
Speed-of-Light roofline page. Capturing DCGM + zymtrace during the cells
raises the roofline rigor (see the Speed-of-light reporting section + Phase D2).
Always-publish with focus + sol_rigor. EVERY run publishes a
sol_complete roofline with a recorded focus (latency|throughput|mixed) +
sol_rigor (L4 ncu | L3 DCGM | L1 zymtrace-proxy | none).
publish_to_lakenever refuses by default - a dcgm_grounded=false /
latency-bound / proxy / no-SoL / 0-plot-ready run lands with the gap RECORDED
on campaign_v1 + warned. An unsupported verdict_tier=verdict
auto-downgrades to draft. The one hard requirement is that report_render
ran first. Pass --strict only when you want publish to refuse an incomplete
campaign. Run perf_tune_report_dcgm_correlate (or the inference-dcgm-correlate
skill) per cell (Phase D2) to raise sol_rigor to L3 - it raises rigor, it is
not a gate.
Tear down cell workloads by label and verify standing/migration objects are
untouched. Record the campaign-id + s3://perf-lake/... paths in the parent
evidence bundle.
