Review summary - CONCERNS
Verdict: Not ready to merge as-is. Mechanically the branch is already conflicted (mergeable: false, mergeable_state: dirty), so it needs a rebase regardless. Substantively, the additive part of this PR looks reasonable, but it also deletes tests/integration/test_lists/qa/llm_spark_core.txt in full (32 entries) with no visible replacement or reference update — that needs to be justified or split out before this lands.
Issues
- [MAJOR]
tests/integration/test_lists/qa/llm_spark_core.txt:0- whole 32-entry Spark core list deleted; possible dangling CI reference and unverified coverage loss - [MINOR]
tests/integration/defs/accuracy/test_llm_api_pytorch_multimodal.py:230- GB10 added to the allow-list without tuning memory-sensitive args (and the PR description describes the opposite effect) - [MINOR]
tests/integration/defs/accuracy/test_llm_api_pytorch_multimodal.py:273-test_nvfp4_no_mtpduplicatestest_nvfp4's setup; parametrise instead, and add-> None - [MINOR]
tests/integration/defs/perf/pytorch_model_config.py:331- fp8 KV cache on the MTP entry only confounds the baseline-vs-MTP comparison - [MINOR]
tests/integration/defs/perf/pytorch_model_config.py:319- confirm the pre-existing baseline pattern does not also match the_mtplabel - [MINOR]
tests/integration/test_lists/qa/llm_spark_perf.yml:51- newgemma_4_26b_a4b_nvfp4entry has no backing model-key addition in this diff - [NIT]
tests/integration/defs/test_e2e.py:991- the Qwen3.6 name also hits the generic"Qwen3"branch, so both--kv_cache_fraction=0.6and--max_batch_size=1are applied
QA view
- Test coverage: partial - the PR is test-only, so the new func/perf/accuracy entries are the coverage. Still uncovered: MTP correctness on Qwen3.6-35B-A3B (only throughput is exercised, no accuracy case), and the fate of the 32 entries removed with
llm_spark_core.txt(Llama3.1-8B FP8/FP4/bf16, GPT-OSS-20B/120B, Qwen3-8B/14B/32B, Qwen3-30B-A3B, Llama3.3-70B FP8/FP4, the sixexamples/servenemotron3 cases) — I only see lines 31-46 ofllm_spark_func.ymland cannot confirm they still run. - SM coverage: the change is NVFP4-only and arch-gated. Code touches sm100 (B200), newly sm121 (GB10/Spark), and Blackwell+ generally via
skip_pre_blackwell. Markers are directionally right, butTestGemma4_26B_A4Bis newly admitted to GB10 while keeping the B200-tunedmax_batch_size=16, and nothing in the diff evidences a GB10 run — that is a new-arch-on-old-arch-settings gap. - Test code: missing return annotation on
test_nvfp4_no_mtp; whole-block copy-paste instead of parametrisation (config drift risk);test_nvfp4_no_mtplisted beforetest_nvfp4in the yml; a new perf list entry (gemma_4_26b_a4b_nvfp4) with no corresponding key addition; and a coverage-reducing file deletion bundled into an additive PR. - Test time: significant - three new perf cases including two 35B MoE runs at 2048/256, two full MMMU evaluations of a 26B multimodal model, and one new 35B quickstart e2e case. The 32 removed entries offset this by an amount I cannot determine from the diff, so the net is unknown; the added-side cost is clearly significant.
- Needs
/qa-verify: yes - a QA test-list file was deleted, a B200-only class is newly enabled on GB10, the MTP perf case depends on an unverified yaml pattern match plus a duplicated checkpoint path, and one new perf entry's model key is unconfirmed.
Possible new issues
- A CI stage that still names
llm_spark_core.txtfails at start-up with a missing-file error instead of running tests. - Spark silently loses the removed coverage if those entries are not present elsewhere in
llm_spark_func.yml. TestGemma4_26B_A4BOOMs on GB10 (single 128 GB unified memory) wheremax_batch_size=16+ chunked prefill + MMMU image inputs fit on a 180 GB B200.- The MTP-vs-baseline perf delta reads as an MTP win when part of it comes from
kv_cache_config.dtype: fp8being set only on the MTP entry. - If the pre-existing baseline yaml pattern is a bare
qwen3.6_35b_a3b_fp4prefix, the_mtplabel matches two entries and could run withoutspeculative_configwhile being reported as the MTP case.
What I could not verify
- Whether anything (Jenkins/CI stage definitions,
--test-listarguments) still referencesllm_spark_core.txt— no such file appears in the diff. - The full contents of
llm_spark_func.yml; only lines 31-46 are visible, so entry-by-entry migration of the removed list is unchecked. - The body of
TestGemma4_26B_A4B::test_nvfp4, so I cannot confirm it enables MTP and thattest_nvfp4_no_mtpis genuinely a different configuration. - The pre-existing
qwen3.6_35b_a3b_fp4entry inpytorch_model_config.py(its pattern string and its KV-cache settings), which both the double-match and the confounded-comparison concerns depend on. - Whether
gemma_4_26b_a4b_nvfp4already exists as a key in_model_paths.pyand in thetest_perf.pymodel list. - Runtime behaviour on GB10 generally — no CI result or perf number is visible to me, only the list entries that would produce them.
Findings not attached to a line
- [MAJOR]
tests/integration/test_lists/qa/llm_spark_core.txt:?- Whole 32-entry Spark core test list deleted with no visible replacement or reference update- This PR is titled "Add func and perf cases" but it also deletes tests/integration/test_lists/qa/llm_spark_core.txt in its entirety (32 entries). Two concrete failure modes:
-
Dangling reference. Test-list files in tests/integration/test_lists/qa/ are normally named by a job/stage definition (Jenkins/CI yml, or a
--test-listargument). The diff contains no change to any file that could still namellm_spark_core.txt, so any job that selects this list will now fail at start-up with a missing-file error rather than running zero tests. I cannot verify from the diff whether such a reference exists — please confirm the consumer was removed or repointed in a separate change. -
Silent coverage loss. Only lines 31-46 of llm_spark_func.yml are visible, and several removed entries have no counterpart in that window:
test_ptp_quickstart_advanced[Llama3.1-8B-FP8/...-FP4/...-bf16],[GPT-OSS-20B],[GPT-OSS-120B],[Qwen3-8b-fp8/nvfp4],[Qwen3-8B-bf16],[Qwen3-14b-fp8/nvfp4],[Qwen3-14B-bf16],[Qwen3-32B-bf16],[Qwen3-32b-nvfp4],[Qwen3-30B-A3B],[Qwen3-30B-A3B_nvfp4_hf],[Llama3.3-70B-FP8/FP4], and the sixexamples/serve/test_serve.py::test_nemotron3_nano_omni_nvfp4[...]cases plustest_nemotron3_super_120b_nvfp4. If those are not present elsewhere in llm_spark_func.yml, Spark loses that coverage without anyone noticing.
Suggested fix: either restore the file, or split the deletion into its own commit/PR that (a) shows the migrated entries and (b) updates whatever references the list, so the reduced scope is auditable. The auto-generated description itself says "Review the removals to confirm that the reduced scope is intentional" — that confirmation should be in the PR, not left to the reviewer.

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: Multiple reasons, each sufficient on its own: (1) a QA test-list file was deleted wholesale and the migration of its 32 entries cannot be confirmed from the diff; (2) a previously B200-only accuracy class is newly enabled on GB10 with unchanged memory settings, so a human should confirm it actually passes (and does not OOM) on Spark; (3) the Qwen3.6 MTP perf case depends on a yaml pattern match and on the _mtp key resolving to the same checkpoint directory — a human should confirm the generated config really contains speculative_config and that the reported MTP speedup is not an artefact of the fp8 KV setting; (4) the new gemma_4_26b_a4b_nvfp4 perf entry needs its model key confirmed before the stage is trusted.

This PR deletes llm_spark_core.txt entirely, removing 30 existing Spark test entries while the stated scope is adding Qwen3.6/Gemma4 cases. I do not see those 30 cases migrated one-for-one in this diff, so this can silently reduce existing QA coverage. Could the core list be preserved, or the migration/removal be made explicit and complete in the same change?
