[None][test] key perf-sanity case identity on test case name

[chenfeiz0326]

Description

A perf test case is identified by a wide tuple of its config values — 27 fields for aggregated runs (s_gpu_type, s_runtime + 15 server + 10 client), up to 46 for disaggregated.

Most of those fields are tunables. l_max_batch_size, s_kv_cache_dtype, s_cache_transceiver_backend, s_spec_decoding_type, l_num_nextn_predict_layers, l_force_num_accepted_tokens, l_load_balancer_num_slots, l_iterations, d_random_range_ratio and b_streaming are adjusted specifically to improve perf on the same test. Changing one forked the case into a brand-new identity with an empty baseline, so the tuning's effect — the reason for the change — became invisible, and the case had to accrue three fresh data points before it could be gated again.

The rest are fixed parameters (l_isl, l_osl, l_concurrency, b_use_nv_sa_benchmark, s_model_name, l_gpus, l_tp/ep/pp/cp, l_gpus_per_node). Those never change for a given case and are already encoded in s_test_case_name, so keying on them adds nothing.

This PR keys on the test case name instead, plus the three things the name does not carry:

Key	Why
s_test_case_name	Encodes model, parallelism, ISL/OSL, concurrency, and (for disagg) the benchmark mode
s_gpu_type	12 case names run on both b200 and gb200
s_runtime	6 case names run on both aggr_server and multi_node_aggr_server
s_branch	Release branches keep their own baseline instead of blending into main's

Validation against the live index

Measured over the 90-day window (11,418 documents):

• Grouping by name yields zero groups in which any fixed parameter varies (0/123 aggr, 0/85 multi-node aggr, 0/110 disagg) — the coarsening never merges two different tests.
• It does merge 37 groups the old key had split on a tunable. Every one of the 37 was split by l_force_num_accepted_tokens (or its ctx/gen-prefixed variants).
• Of those 37, 35 keep an unchanged regression band; 2 shift. That is the expected one-off transient as a rejoined case's rolling baseline re-settles, and all 37 splinters sit at the edge of the 90-day window, so it self-clears.

Why s_benchmark_mode is not a match key

It is null on every aggregated record (3,721 aggr_server + 3,242 multi_node_aggr_server), so it has no discriminating power there — while the name still carries the mode (38 of 88 and 24 of 54 unique aggregated names start with ctx_only-, since ctx_only runs on the aggregated path). On multi_node_disagg_server it is exactly redundant: the name prefix equals s_benchmark_mode in 3036/3036 documents, and no name-group spans more than one mode.

Adding it would also be a matching hazard: benchmark_data_matches treats None and "e2e" as different values, so keying on a field that is null for two-thirds of the corpus would break lookups against records written before it existed.

Pre-merge branch substitution

s_branch becoming a match key needs one piece of new logic. get_history_data restricts history to b_is_post_merge: True documents, and a pre-merge run records s_branch = "github-pr-<N>", which has no post-merge history. Matching on it would return nothing and turn every pre-merge regression check into a silent no-op.

process_and_upload_test_results therefore resolves a baseline branch (PERF_BASELINE_BRANCH, default main) and substitutes it into a lookup-only copy of the data. Two details matter:

1. The substitution happens before get_common_values, which pushes single-valued match keys into the OpenSearch must clause — an unsubstituted s_branch there would filter the history away before matching even runs.
2. The uploaded documents keep their true s_branch, so pre-merge rows remain identifiable as such.

Callers that do not key on s_branch (module perf, visual gen) are gated out and unaffected.

This completes the branch half of #18127, which fixed s_branch derivation but explicitly noted that s_branch was still absent from match_keys, leaving release-branch points joining main's baseline.

Pre-existing issues resolved as side effects

• The gen_only filter that drops the gen transceiver backend from the key compared against "gen_s_cache_transceiver_backend", while the prefixing helper produces "s_gen_cache_transceiver_backend" — so it never matched and was dead code. It is deleted along with the block it lived in.
• world_size is read by jenkins/scripts/perf/submit.py to size the Slurm allocation but is never parsed into ServerConfig, so a 1-GPU and a 4-GPU variant of the same config (super_ad_ws1_1k1k / super_ad_ws4_1k1k) shared one baseline and one curve. Their names differ, so keying on the name separates them. world_size is still unparsed and would matter again if anything keyed on l_gpus.

Out of scope

match_mode: "scenario" becomes inert — its intent ("don't fork this case when knobs drift") is now the default for every case. The option is still parsed so existing yamls stay valid; removing it from the ~30 configs that set it is left as a follow-up to keep this PR to one concern.

The CI Dashboard maintains an independent copy of the same field list and is being updated to match, so the two systems share a single identity definition.

Test Coverage

tests/unittest/tools/test_perf_sanity_matching.py — rewritten for the new key set:

• the key set is exactly name + gpu_type + runtime + branch
• a tuning change (l_max_batch_size, s_kv_cache_dtype, l_iterations, l_force_num_accepted_tokens) still matches, i.e. keeps its history
• name / gpu_type / runtime / branch each still discriminate
• s_benchmark_mode is not a key, and None vs "e2e" no longer breaks a disagg match
• pre-merge branch substitution finds the baseline while leaving the uploaded s_branch intact

PR Checklist

Please review the following before submitting your PR:

• PR description clearly explains what and why.
• The PR title follows the required format.
• Test cases are provided for new code paths.
• Any new dependencies have been scanned for license and vulnerabilities.
• CODEOWNERS updated if ownership changes.
• Documentation updated as needed (README_test_perf_sanity.md).
• The reviewers assigned automatically/manually are appropriate for the PR.

Dev Engineer Review

• Perf sanity identity uses s_test_case_name, s_gpu_type, s_runtime, and s_branch.
• Tunable fields and s_benchmark_mode remain stored but do not affect identity.
• l_iterations can still fork cases when it changes a derived disaggregated client name.
• Pre-merge history lookups use PERF_BASELINE_BRANCH or main.
• Uploaded records retain the original branch.
• Matching logic is centralized in get_test_case_match_keys().
• Documentation, implementation, and tests use the same matching policy.
• Validation found no fixed-parameter collisions and identified 37 groups previously split by accepted-token settings.
• No test-list files or unrelated configuration files changed.
• The selected multi-GPU CI run failed. The run requires the ci: full pre-merge approved label before re-triggering.

QA Engineer Review

Test-code changes include:

• Added coverage for match-key selection, tuning changes, discriminating fields, benchmark mode, and pre-merge branch handling.
• Added test_disagg_iterations_come_from_multi_round().
• Added test_iterations_fork_a_case_through_the_derived_name().
• Added test_an_explicit_client_name_keeps_the_case_across_an_iterations_change().
• Added complete type annotations to the branch-regression test harness and its six test functions.
• Removed obsolete scenario and configuration matching tests.

No tests/integration/test_lists/ files were modified. The changed test functions have no corresponding test-db/ or qa/ entries in this change. Direct unit-test coverage is sufficient.

Walkthrough

Perf sanity matching now uses four shared identity fields. Pre-merge history lookups substitute a baseline branch while preserving the original uploaded branch. Documentation and tests cover matching, iteration-derived names, and branch lookup behavior.

Changes

Performance sanity matching

Layer / File(s)	Summary
Unified matching contract and validation tests/test_common/perf_sanity_matching.py, tests/unittest/tools/test_perf_sanity_matching.py	Matching uses test-case name, GPU type, runtime, and branch. Tests cover disaggregated iteration-derived names and explicit client names.
Integration matching wiring tests/integration/defs/perf/test_perf_sanity.py, tests/integration/defs/perf/README_test_perf_sanity.md	Integration code uses get_test_case_match_keys() for aggregated and disaggregated results. Database field prefixing remains in place. Documentation describes iteration effects on case identity and history.
Pre-merge baseline lookup tests/integration/defs/perf/perf_regression_utils.py, tests/unittest/others/test_perf_regression_branch.py	Pre-merge history lookups use PERF_BASELINE_BRANCH or main, while uploaded records retain the original branch. The branch-routing test harness now includes complete type annotations.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 978c2

The matching change is intended to preserve history across tuning, but derived case names can still include tunable iteration values, allowing tuning changes to create separate baselines and bypass regression comparisons. The added tests also need a scoped environment setting and strict zip usage before merge.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Keep tuning values out of s_test_case_name.

l_iterations is declared tunable, but ClientConfig derives its default name from iterations, and the upload path includes that name in s_test_case_name. Changing benchmark.multi_round therefore changes this match key, forks baseline history, and can make the regression check find no history.

Use a stable scenario identifier for matching, or ensure generated identity names exclude all tunable values. The new tuning test keeps s_test_case_name constant, so it does not cover this production path.

[chenfeiz0326]

Partly agreed — the mechanism is real and I've pinned it, but I'm not taking the proposed remedy, and I want to be precise about why.

Confirmed, end to end. benchmark.multi_round → the client's iterations (test_perf_sanity.py:2270) → ClientConfig's derived con<C>_iter<N>_isl<I>_osl<O> (:1119) → the client half of s_test_case_name, which is a match key. Loading the real ClientConfig yields con12_iter12_isl50000_osl2048, which is exactly the shape of live disagg case names. So changing multi_round renames the case, and a renamed case has no history and no pre-merge regression check.

The split you didn't have visibility into. All 190 client blocks under tests/scripts/perf-sanity/ set an explicit name, and none use the default:

path	client name	changing iterations
aggregated (190/190 blocks)	explicit from yaml	case and history kept — this is where dropping l_iterations pays off (93 of those names carry a now-stale iter<N>)
disagg (no client name)	derived, includes iter<N>	case renamed, history lost

Two corrections to the finding. It is not a regression: l_iterations was itself a match key before this PR (_CLIENT_MATCH_KEYS at 6c1ce33), so that field already forked the case, and more aggressively. And the fork is arguably correct — iterations sets how long the measurement runs, so iter10 and iter12 amortize warmup differently and don't measure the same quantity. Sharing one baseline across them would inject a step change into the curve.

Why not the prescribed fix. Making generated names exclude tunables, or matching on a new stable scenario id, renames every disagg case — discarding the 90 days of history this PR exists to preserve, and breaking the dashboard's section_id (name|branch|gpu) and every nvbug association keyed on it. That trades a documented, intended fork for a silent global one.

What I did instead (978c212):

• Corrected the README: it no longer lists l_iterations as fork-free, and states the actual boundary, both paths, and why the disagg fork is intended.
• Took your test point — test_matching_ignores_tuning_changes did assume a constant name, and now says so explicitly. Added tests against the real ClientConfig, not a re-implemented f-string, covering both the derived-name fork and the explicit-name no-fork.
• PerfSanityTestConfig's constructor shells out to nvidia-smi and raises without a GPU, so the parser isn't unit-testable; the multi_round → iterations link is asserted over its AST instead. I added that specifically because my first version of these tests passed when I unwired multi_round — the mapping was only in a docstring.

Mutation-verified: dropping iterations from the derived name (1 failed), restoring l_iterations to the match key (3 failed), and unwiring multi_round (1 failed).

Review summary - CONCERNS

Verdict: Mechanically mergeable and mergeable_state is only blocked (pending required reviews), and the redesign is well-reasoned; but the one piece of new production logic — pre-merge branch substitution — has no direct test, so I'd resolve that before merge.

Issues

• [MAJOR] tests/integration/defs/perf/perf_regression_utils.py:499 - pre-merge branch-substitution routing is untested
• [MINOR] tests/integration/defs/perf/test_perf_sanity.py:2608 - disagg key drops num ctx/gen servers, relies on unverifiable index claim

QA view

• Test coverage: partial - test_perf_sanity_matching.py covers the new key set, tuning-invariance, all four discriminators, and benchmark-mode exclusion. Uncovered: the actual process_and_upload_test_results substitution wiring (lookup copy -> get_common_values/get_history_data, original -> post_new_perf_data), which the test only re-implements by hand.
• SM coverage: architecture-independent - no get_sm_version, arch guards, or fp8/nvfp4 paths touched.
• Test code: test_pre_merge_branch_substitution_finds_baseline validates the concept but never calls the production function, so it cannot catch a wiring regression; no assertion on the PERF_BASELINE_BRANCH override.
• Test time: small - a few pure-Python unit cases over in-memory dicts, no model/GPU.
• Needs /qa-verify: yes - this is a change to perf-regression matching infrastructure whose new branch-substitution logic fails open (silent green no-op); a human should confirm a pre-merge run really matches the baseline branch and that disagg names don't collide across server topologies.

Possible new issues

• If the substitution wiring ever regresses, pre-merge history matches nothing and regression gating silently passes — the exact failure this block prevents, undetectable because it's green.
• Dropping l_num_ctx_servers/l_num_gen_servers/s_benchmark_mode from the disagg key merges distinct disagg configs that share a name; safety depends on the quoted 90-day index validation.

What I could not verify

• The import block of perf_regression_utils.py is not in the diff, so I could not confirm os (used for os.environ) is imported.
• The 90-day live-index numbers in the PR body (0/123, 0/85, 0/110 groups, 3036/3036 name==mode) are external evidence I cannot check; the disagg coarsening's correctness rests on them.
• The full argument list of prepare_regressive_test_cases is not shown, so I could only confirm from the description (not the diff) that it and post_new_perf_data receive the original-branch data.

Review summary - Approve (non-blocking)

Approving so this is not blocked on me. The points raised in my review comment above are non-blocking — please read them and address what you agree with before merging.

Worth doing before this is relied on: This changes the perf-regression matching infrastructure itself, and the new pre-merge branch-substitution logic (whose failure mode is a silent green no-op of regression gating) has no direct test. A human QA should confirm a pre-merge run actually matches the baseline branch and that post-merge/regression paths still behave, plus that disagg names do not collide across server topologies.

- Around line 191-192: Scope an environment patch around the `ten` and `twelve`
`client_config` constructions so `BOLT_ITER_MULT` is set to `"1"` while their
derived names are generated. Keep the existing assertions and matching behavior
unchanged, and ensure the environment value is restored after the test block.
- Line 168: Update the zip call in the node key/value iteration to pass
strict=True, preserving the existing iteration while enforcing equal-length
node.keys and node.values sequences.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Isolate the derived-name test from BOLT_ITER_MULT.

If a profile-generation job sets BOLT_ITER_MULT above 1, ClientConfig multiplies both iteration values before it derives name. The assertions on Lines 194-195 then fail despite unchanged matching behavior. Set BOLT_ITER_MULT to "1" in a scoped environment patch around these constructions.

Proposed fix

+from unittest.mock import patch
+
-    ten = client_config(_disagg_client_data(10), "example_model")
-    twelve = client_config(_disagg_client_data(12), "example_model")
+    with patch.dict("os.environ", {"BOLT_ITER_MULT": "1"}):
+        ten = client_config(_disagg_client_data(10), "example_model")
+        twelve = client_config(_disagg_client_data(12), "example_model")
