| # DeepSeek-V4-Pro disaggregated on GB300 (1P1D, TP=4, MXFP4) — sglang + | ||
| # dynamo frontend. Ported from NVIDIA/srt-slurm PR #75 | ||
| # (recipes/gb300-fp4/1k1k-dsv4/disagg-1p1d-tp4-mxfp4.yaml). GB300 sibling of | ||
| # the dsv4-sglang-disagg-gb200-1p1d-dep8-tep8 recipe in this directory tree. | ||
| # | ||
| # Topology: 1 prefill node + 1 decode node, each TP=4 on a single GB300 | ||
| # (4 GPUs / node). KV transfer over NIXL. Targets steady decode TPOT under | ||
| # moderate-to-high concurrency. | ||
| # | ||
| # Local deltas vs upstream PR #75: | ||
| # * benchmark.type = sa-bench (upstream uses "manual" because they pair | ||
| # with a separate sa-bench launcher; our sweep harness drives sa-bench | ||
| # in-recipe). | ||
| # * Disagg timeout triple + NCCL_MNNVL/CUMEM env vars copied from the | ||
| # GB200 sglang sibling — same handshake-stability rationale. | ||

They are correct that bug_002 and bug_005 describe the same underlying issue — the synthesis agent merged them, and this single comment now represents both. The underlying issue is real and confirmed by 6 verifiers across the two original bugs; only the duplication concern was raised, not the validity. |

🟡 The new recipe header at lines 5-6 and 16-17 of disagg-gb300-1p1d-tp4.yaml refers to a 'GB200 sglang sibling' (
dsv4-sglang-disagg-gb200-1p1d-dep8-tep8) that does not exist in this repository — the only DSv4 GB200 recipes live undersrt-slurm-recipes/vllm/deepseek-v4/, andlaunch_gb200-nv.shroutesdsv4-fp4exclusively through thedynamo-vllmbranch. This is a comment-only inconsistency with no runtime impact, but the PR description's claim that this 'mirrors the gates the GB200 launcher already uses for the SGLang sibling' is also inaccurate. Suggest editing the header to drop the sibling references or point at the actual upstream PR #75 source instead.Extended reasoning...
What the bug is
The new file
benchmarks/multi_node/srt-slurm-recipes/sglang/deepseek-v4/1k1k/disagg-gb300-1p1d-tp4.yamlcarries a header comment (lines 4-6) and a 'Local deltas' block (lines 16-17) that twice reference a sibling recipe —dsv4-sglang-disagg-gb200-1p1d-dep8-tep8— said to live 'in this directory tree'. It also claims that the disagg-timeout triple andNCCL_MNNVL_ENABLE/NCCL_CUMEM_ENABLEenv vars were 'copied from the GB200 sglang sibling'. No such sibling exists in the repo today.The specific code path / proof
Step-by-step:
benchmarks/multi_node/srt-slurm-recipes/sglang/contains only the new GB300 file added by this PR — no GB200 sglang DSv4 file is present.dsv4-sglang-disagg-gb200returns only the self-reference inside this new recipe's header comment.benchmarks/multi_node/srt-slurm-recipes/vllm/deepseek-v4/), not sglang.runners/launch_gb200-nv.shroutesdsv4-fp4only through thedynamo-vllmbranch (the elif onFRAMEWORK==dynamo-vllm) and the overlay block copies fromsrt-slurm-recipes/vllm/deepseek-v4. There is nodynamo-sglangbranch fordsv4on GB200, so the PR description's claim 'Mirrors the gates the GB200 launcher already uses for the SGLang sibling' is also off.perf-changelog.yamlhasdsv4-fp4-gb200-dynamo-vllmbut no GB200 sglang DSv4 entry.Why existing code doesn't prevent it
YAML comments are free-form text; nothing in the launcher, srtctl, or sweep harness validates them.
Impact
Zero runtime impact — the field values themselves are valid. The cost is purely documentation: a future reader trying to compare this recipe against the alleged sibling, or wanting to update env-var rationale in lockstep, will hit a dead-end.
How to fix it
Either:
dynamo-vllmrecipe undersrt-slurm-recipes/vllm/deepseek-v4/, name that file instead and adjust the wording (it isn't an sglang sibling).
