[None][infra] Select modeling_v2 CI tests by the node a change lands in by WeiHaocheng · Pull Request #20829 · NVIDIA/TensorRT-LLM

WeiHaocheng · 2026-10-22T14:15:11Z

Description

ModelingV2Rule claimed every change under tensorrt_llm/_torch/_experimental/modeling_v2/ and kept every modeling_v2 test-db entry. Editing one target ran every target's unit tests and accuracy gates. Adding a cell to a shared catalog entry did the same.

This PR maps each changed file to the tests it can reach.

Selection.

Change	Selected
A file under `models/<family>/`	The unit tests of its node, plus the accuracy gate of every target under that node. The node is the nearest directory at or above the file that holds a target (`modeling.py`), or else the family.
A target's `cells.py`	Only the unit tests of the catalog entries it imports, at their mirrored paths.
Anything else (catalog, resolver, `models/__init__.py`)	Every modeling_v2 entry, as before.

A target's gate is Test<TargetClass> in accuracy/modeling_v2/test_<family>.py. The class name is read from the import line in the family's routing.py.
The tests directly under unittest/_torch/modeling_v2/ (claims, routing, contracts) run for every change.
When test-db lists a node more coarsely than the rule selects, the longest entry that covers the node is kept. A family is listed as one directory entry, so a change to one of its targets runs that family's unit tests.
When the tree on disk cannot answer, the file falls back to the wider selection. Examples: a deleted routing.py, an unparsable cells.py, or a cells.py that names an entry with no test at the mirrored path.

Target cells. Some cells in the catalog entries name a shipped target, for example "deepseek default at attention TP8 …". Those 90 cells move into that target's cells.py, written as CELLS = {Entry: (Cell(...), ...)}.

The entries keep the cells that belong to the op whoever calls it.
The entry tests drive the union through certified_cells(). A spec declared more than once runs once.
The certified cell count of every entry is unchanged.
Nothing in a forward reads CELLS. A target can therefore add shapes without touching the catalog and without running any target's gate.

Claims tests. Three new checks:

A cells.py sits beside a target's modeling.py and imports only catalog entries. The target must itself call each of those entries, and each entry's mirrored test must drive certified_cells(.
Every routed target has an accuracy gate of its name, and every gate names a routed target.
Every modeling_v2 unit test file is reached by some test list. Per-file entries do not pick up a new file by themselves.

Test lists.

The l0_b300 entry unittest/_torch/modeling_v2 --ignore=…/comm is split into one entry per catalog entry test, one per model family, and one per whole-tree GPU test. The whole-tree tests that are already in l0_cpu are no longer repeated on GPU.
Its directory waive (nvbug 6853741) is removed. The full non-comm suite passes on current main (below), including the three input_not_mutated tests once waived under nvbug 6852473.

This PR is stacked on #20789, which adds @routes. The first commit here belongs to that PR.

Test Coverage

GB300, one pytest process as CI runs it, unittest/_torch/modeling_v2 --ignore=…/comm:
- Before the change: 2065 passed, 11 skipped, 0 failed.
- After the change: 2070 passed, 11 skipped, 0 failed. The 5 extra tests are the new claims checks.
- The skips are routing parametrizations for GPUs other than sm_103.
tests/unittest/scripts/cbts/test_modeling_v2.py (new) builds a small tree and checks:
- A target change selects its family's unit tests and only its own gate.
- An ops-only directory belongs to its family.
- A family file selects all of the family's gates.
- A cells.py change selects only its entries' tests.
- A catalog change selects everything.
- A cells.py that names an unmirrored entry falls back to its node.
Ran the rule against the real test-db:
- A gpt_oss modeling.py change keeps the gpt_oss family entry, its 6 gate parametrizations and the whole-tree tests.
- A qwen4_exp cells.py change keeps 4 entry tests and the whole-tree tests.
scripts/check_test_list.py --validate is clean.

PR Checklist

Dev Engineer Review

ModelingV2Rule now selects modeling_v2 tests from changed model nodes and catalog entries imported by target cells.py files. It retains whole-tree tests and broadens selection when it cannot resolve the tree or imports. Verify node resolution, catalog matching, and fallback behavior.

Routing now uses decorator-based registration. Importing models imports family routing modules. The package no longer exports MODELING_V2_ROUTERS, and _router_index.py removes routing_module. Verify callers use the registry API and that unknown architectures preserve the intended auto and require behavior.

The change moves target-specific certified cells into three target cells.py files. Operator tests combine target cells with catalog cells. Several catalog cell sets shrink or change. Verify that required configurations remain covered and that target-cell discovery does not add unnecessary import work.

The GB300 test list replaces the aggregate modeling_v2 entry with explicit operator tests, model-family paths, and accuracy gates. The CPU list includes the claims test. The directory-wide modeling_v2 waiver was removed. The objectives report a failed CI run for commit 85d133e and a later successful run for bb7331a, while also reporting a failed pipeline. Author-reported test results and validation are not independently verified. No current review findings or severity counts were supplied.

QA Engineer Review

Changed tests include the CBTS selection tests, _cells.py, operator tests, claims tests, and the Qwen4-Exp weight-path test. The CBTS tests cover target, family, routing, cells, catalog, and fallback selection. Claims tests cover target-cell relationships, accuracy gates, routing, and test-list coverage. test_modeling_v2_claims.py is listed in l0_cpu.yml; the changed tests/unittest/scripts/cbts/test_modeling_v2.py was not found in the searched CI or manual-QA lists.

l0_b300.yml explicitly lists the changed operator tests and relevant model-family paths. l0_gr100.yml adds GLM-5.2 target test directories for one-GPU post-merge runs and a comm directory for a four-GPU post-merge run. The coverage verdict is needs follow-up because the CBTS test has no located test-list entry and the reported CI pipeline failed.

Walkthrough

The change registers modeling-v2 routes through decorators, adds target-specific certification cells, and updates tests to combine operation and target cells. It also selects modeling-v2 tests based on changed paths and updates integration test lists and certification checks.

Changes

Modeling-v2 certification and test selection

Layer / File(s)	Summary
Register model-family routes `tensorrt_llm/_torch/_experimental/modeling_v2/_router_index.py`, `tensorrt_llm/_torch/_experimental/modeling_v2/models/*/routing.py`, `tensorrt_llm/_torch/_experimental/modeling_v2/models/__init__.py`, `tensorrt_llm/_torch/_experimental/modeling_v2/__init__.py`, `tests/unittest/_torch/modeling_v2/test_modeling_v2_claims.py`	Family routing modules register route functions by architecture. The resolver reads the registry populated when the models package imports those modules.
Update operation cell catalogs `tensorrt_llm/_torch/_experimental/modeling_v2/catalog/*`	Catalog documentation distinguishes operation-owned cells from target-specific cells. Operation catalogs change their listed certification cases across activation, attention, GEMM, MoE, normalization, and quantization.
Define target-owned certification cells `tensorrt_llm/_torch/_experimental/modeling_v2/models/*/cells.py`	DeepSeek, GPT-OSS, and Qwen4 targets define CELLS mappings for their operation configurations.
Combine target cells in certification tests `tests/unittest/_torch/modeling_v2/`, `tests/integration/test_lists/`	Certification tests use combined, deduplicated cell sets. Static checks validate target cell imports, mirrored tests, route targets, accuracy gates, and test-list coverage. Integration test lists add modeling-v2 paths and GLM-5.2 tests; the broad modeling-v2 waiver is removed.
Select tests from changed paths `jenkins/scripts/cbts/cbts/command/main.py`, `jenkins/scripts/cbts/cbts/rules/modeling_v2.py`, `tests/unittest/scripts/cbts/test_modeling_v2.py`	ModelingV2Rule receives the repository root and selects test prefixes based on changed model or cells paths. It retains whole-tree tests and falls back to all entries when paths cannot be resolved.

brnguyen2

The selection logic reads well and the new cbts unit test passes locally, but the test-db split ships a broken entry that fails the B300 stage deterministically, so this needs a fix before merge.

Blocking: l0_b300.yml lists unittest/_torch/modeling_v2/models/gpt_oss, and there is no such directory under tests/unittest/_torch/modeling_v2/models/ (only deepseek_v3 and qwen4_exp exist). test_unittests_v2 runs each entry as pytest <entry>; pytest exits 4 (file or directory not found) and the harness fails the stage. The rule selects that entry for every gpt_oss target change via the covering fallback, and for every catalog/resolver change via the all-entries path. Details inline.

The Test Coverage section ran the old whole-tree entry as one pytest process. That does not exercise the 26 new entries through the harness, which is what let this through. Please run the B300 stage on this PR with the new list (CI should show it) and, ideally, extend test_every_unit_test_is_in_a_test_list with the reverse check so a listed modeling_v2 path that does not exist fails on CPU.

Ticket: this is a nontrivial infra change that also removes a waive citing nvbug 6853741. Please put a JIRA or the NVBug in the title instead of [None].

Other notes:

The @routes commit from #20789 is in this diff as stated; I only skimmed it. No remaining users of MODELING_V2_ROUTERS / routing_module, so the export removal is clean.
The new cells.py files import underscore-prefixed catalog names (MlaRopeAppendPagedKvAssignQ._R1, _QWEN4_DENSE, _QWEN4_VISION). Functional, but it couples targets to catalog privates; consider exporting those dicts without the underscore.

Thanks for the review. Addressed in a86d079:

Dropped the models/gpt_oss entry, and added the reverse check to test_every_unit_test_is_in_a_test_list.
Aligned the rule's target-import regex with the claims test.
The fragments the cells.py files share are now public: R1 on the three DeepSeek ops, GPT_OSS on the two gpt_oss ops, and QWEN4_DENSE/QWEN4_VISION in thop_attention. Fragments no target imports stay private.
_cells.py dedup: no spec holds a nested mapping, so no change (see inline).
The two qwen4_exp QSA failures from the first CI run predate this PR. They had never run in CI because of the directory waive. They are now waived per test under https://nvbugs/6981517 (a5697bf), which records the causes.

239-241: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve the broad fallback for unresolved cells.py files.

_cells_tests() returns None for parse, read, import, or mirrored-test failures. It can also return an empty set when no catalog operation is resolved. This branch treats both cases as resolved or falls through to node-specific selection. apply() can then omit affected catalog-operation tests and keep only whole-tree tests.

Return tests or None from this branch so unresolved cell files select every modeling-v2 entry.
Proposed fix
 if rel.name == "cells.py":
     tests = self._cells_tests(rel)
-    if tests is not None:
-        return tests
+    return tests or None

Replace the hand-maintained MODELING_V2_ROUTERS table with a @routes(...) decorator on each family's route function. models/__init__.py imports every family's routing module, which registers its route; the resolver reads the registry through registered_routes(). Target modeling code is still imported only on the route branch that returns it. The claims test reads the registry instead of the table, and its orphan check now catches a routing.py that is not imported or carries no @routes. Signed-off-by: Fred Wei <20514172+WeiHaocheng@users.noreply.github.com>

ModelingV2Rule claimed every change under modeling_v2 and kept every modeling_v2 test-db entry. It now maps each changed file to the tests it can reach: - a file under models/<family>/ selects the unit tests of its node (the nearest directory at or above it holding a target, or the family) and the accuracy gate of every target under that node, read from the family's routing.py; - a target's cells.py selects only the unit tests of the catalog entries it imports; - anything else (catalog, resolver) still selects every entry. Cells that name a shipped target move out of the catalog entries into that target's cells.py; the entry tests drive the union through certified_cells(). Claims tests now check cells.py placement and imports, that every target has an accuracy gate of its name, and that every modeling_v2 unit test is in a test list. The l0_b300 directory entry is split per catalog entry test, per model family and per whole-tree test, and its directory waive (nvbug 6853741) is dropped: the full non-comm suite passes on GB300. Signed-off-by: Fred Wei <20514172+WeiHaocheng@users.noreply.github.com>

- Drop the l0_b300 entry unittest/_torch/modeling_v2/models/gpt_oss: gpt_oss has no target-level unit tests, so the entry named nothing. - test_every_unit_test_is_in_a_test_list also checks the other direction: every listed modeling_v2 entry holds a test file. - The CBTS rule reads routing.py with the claims test's pattern. - Make public the spec fragments the cells.py files share (R1, GPT_OSS, QWEN4_DENSE, QWEN4_VISION).

Both files became cpu_only and run in l0_cpu. The GPU stage runs with -m 'not cpu_only', so it selects nothing from them and pytest exits 5. Signed-off-by: Fred Wei <20514172+WeiHaocheng@users.noreply.github.com>

…erence gate Both backends requantize the SwiGLU output to NVFP4, so a last-place fp32 difference at an e2m1 rounding boundary moves one element by a whole code. On B300 that put one token at 4.96e-3 against a 3e-3 bound, with a mean of 4.8e-6. Signed-off-by: Fred Wei <20514172+WeiHaocheng@users.noreply.github.com>

The target is certified on sm_107 and its tests skip elsewhere, so they go in the Rubin list: the single-GPU op directories in the one-GPU block, and the 4-rank comm matrices in a 4-GPU block. Signed-off-by: Fred Wei <20514172+WeiHaocheng@users.noreply.github.com>
