From b032812623b097ea53d8bd317371ed65599405c8 Mon Sep 17 00:00:00 2001 From: Michael Roy Date: Wed, 8 Jul 2026 12:07:53 -0700 Subject: [PATCH 1/6] docs: finalize rocm bench load plan (Phase 1, vetted) Rewrite the bench load-generator plan after an adversarial review pass against current main. Tightened to ~360 LOC / one new file: writer lives in collectors (daemon has no csv dep), top-level 'rocm bench load' verb (Dash untouched), one aggregate row per cell, distinct opt-in output CSV, http-only with a clear https rejection, and a fixed not-an-official- benchmark caveat in --help and stdout. Zero shipped deps; one dev-dep (wiremock). Supersedes the 2026-06-22 draft.

Why this is a small change + +The **consumer half already ships on `main`** (verified). Rows flow: + +``` +CSV file ──CsvBenchTailer.drain()──▶ runner drain ──▶ StateEvent::BenchmarkRows + (collectors/bench_tail.rs) (daemon/runner.rs:576) + BenchRing.push + + broadcast BenchmarkRowsAppended + │ + TUI AppState.bench_rows ◀── client subscribe ◀──┘ + bench tab (rollup + rows table + sparkline) +``` + +The bench tab in the Observe pane is inert only because **nothing produces +rows**. The single missing piece is a load generator. MVP = a generator that +appends normalized rows to the file a running daemon already tails +(`RunnerOptions.bench_csv` ← `config.dashboard.daemon.bench_results_dir`), so +the whole consumer pipeline lights up with **zero daemon/protocol/UI changes**. + +## 1. Final scope + +**Phase 1 IS:** one concurrency-sweep load generator that POSTs synthetic +`/chat/completions` requests to a **local `http://` OpenAI-compatible endpoint**, +computes client-side `gen_tps` **and** `prompt_tps` from a wall makespan, writes +**one aggregate `BenchmarkRow` per concurrency cell** as append-only CSV to a +**distinct self-labeled file**, exposed as `rocm bench load`. All quality fields +default → verdict `Unknown`. Every run prints a fixed "not an official +benchmark" note. + +### Cut from the original draft (with why) + +| Cut | Why | +|---|---| +| Second file `daemon/src/bench_load.rs` | Daemon has **no `csv` dep**; writer lives in collectors (owns csv/reqwest/tokio). Deletes a file, a manifest edit, a dep hop. | +| `run_sweep` public fn | One-caller 3-line loop; inline it. YAGNI. | +| `LoadSpec.prom_host` + server-side Prometheus peaks | Plan's own Phase 1.5. Leave `max_running/max_waiting = None`. | +| One-row-per-request | Only Pass^N needs per-request rows, and it's `Unknown` here. Rollup+table+sparkline render fine with 1 row/cell. | +| "record client + server gen_tps distinctly" | Schema has **one** `gen_tps` field + no second UI column. Not representable in MVP. | +| reqwest `json`/TLS feature adds | Hand-serialize with `serde_json` + `.text()` (`lemonade.rs` pattern); localhost `http` needs zero manifest change. | +| Folding bench into `Dash` struct-variant | Would make Dash the only variant mixing flags + `#[command(subcommand)]` — untested clap precedence. Use top-level `Command::Bench`. | +| `anyhow` in writer signature | Collectors has no `anyhow`; use `thiserror` (already present). | +| Default `--out` → shared `bench_results_dir` | Silently pollutes users' real agent-bench comparison CSVs with Unknown-quality rows. Opt-in only. | +| "byte-compatible with external tools" claim | **False** if we auto-serialize the struct (~60 cols ≠ upstream 30-col order).

'rocm bench load' fans out concurrent /chat/completions requests at a local OpenAI-compatible endpoint, measures client-side gen_tps and prompt_tps over a wall makespan, and appends one aggregate BenchmarkRow per concurrency cell to a distinct CSV a running daemon tails -- so the bench tab lights up live with zero daemon/protocol/UI changes. - collectors/bench_load.rs: LoadSpec, run_cell (JoinSet + owned-permit Semaphore, hand-serialized POST like lemonade.rs, per-request Result isolation, pinned makespan), run_and_append_csv (O_APPEND single newline-terminated write_all per row, header-if-empty, refuses on header mismatch). thiserror errors; no new shipped deps. - top-level Command::Bench/Load (Dash untouched); http-only with a clear https rejection; distinct opt-in --out (never the shared results dir); raw-throughput-vs-agent-workload caveat in --help and stdout. - tests T1-T5 (wiremock dev-dep) under --test-threads=1; T2 verifies the concurrency cap is actually enforced. Quality fields default to Unknown so throughput rows never claim pass/fail.

Phase 1.5 (collectors, vLLM-only, zero new deps): each cell scrapes the endpoint's /metrics before/after for cumulative TTFT/TPOT histogram deltas, and a lightweight mid-cell poller (250ms, 1s scrape timeout, AtomicBool stop + join) tracks true peak running/waiting reqs. CSV header extended 14->18 (max_running_reqs, max_waiting_reqs, ttft_ms, tpot_ms); server-side gen_tps discarded in favour of the client-measured value. Non-vLLM endpoints degrade to None, never stalling the sweep. Latency shows in the bench detail panel. Phase 2: - auto-ramp (--auto-ramp): doubling sweep 1..128 that stops on a pure should_stop_ramp (plateau <5% gain, or queue saturation guarded on running>0, or hard cap); rows append incrementally so the tab fills live. - TUI trigger: press 'b' on Observe to open a bench-run form that spawns 'rocm bench load' via the existing job system, defaulting --out to the daemon-tailed CSV so rows stream into the bench tab. No protocol/server/ runner changes (Command::RunBench deliberately not built). Tests: Prometheus delta + non-vLLM degradation + 18-col round-trip + header guard; deterministic should_stop_ramp cases incl. an at-rest-peaks regression guard; overlay invariants + SpawnJob args + https rejection. All under --test-threads=1; clippy --all-targets -D warnings clean.

Remove the stray /data/ segment so both configs resolve to the same absolute path the producer uses. - Honor ROCM_CLI_DATA_DIR on the daemon side: rocm-core's default now resolves through the same AppPaths::discover() the producer uses (not bare default_data_dir(), which ignores the override), and rocm-dash-core's default honors the override too. Previously, with the override set, a plain `rocm bench load` wrote a file the daemon never tailed. - Add a cross-binary regression test asserting the producer default (default_bench_csv_path) and the daemon-tailed default (DashboardDaemonConfig::bench_results_dir) resolve to the same path, plus an override-precedence test in rocm-dash-core. - Reword the Bench empty-state copy: "bench directory" -> "bench results file" (bench_results_dir is a single tailed file, not a directory). - Fix the --out help text's default path (drop the stray /data/).

Verified with `cargo xtask manifest --check`. - Harden CsvBenchTailer::drain against the CodeQL rust/path-injection alert at the File::open sink: the tailed path is derived from config / $ROCM_CLI_DATA_DIR, so route it through validated_read_path(), which canonicalizes the path (resolving symlinks and `..`) and rejects traversal before opening. The bench results file is intentionally user-configurable to any location, so canonicalization — not a fixed-root containment check — is the correct barrier. Canonicalization fails on an absent file exactly as the previous bare File::open did, so the daemon tick loop keeps tolerating a not-yet-created CSV.
