**目标:**将 SGLang 镜像从 lmsysorg/sglang:v0.5.19-cu130 更新为 lmsysorg/sglang:v0.5.21-cu130。
**基线:**2026-09-16 · lmsysorg/sglang:v0.5.19-cu130
平均延迟 · 来源: API 1, API 2;数值及异常说明见上表。

Pin lmsysorg/sglang:v0.5.21-cu130 by digest and replace the removed
--cuda-graph-max-bs and --disable-piecewise-cuda-graph flags with their
v0.5.19 alias targets --cuda-graph-max-bs-decode and
--cuda-graph-backend-prefill=disabled.

将 B200 FP4 SGLang 镜像更新至按摘要固定的 lmsysorg/sglang:v0.5.21-cu130,
并将已移除的 --cuda-graph-max-bs 与 --disable-piecewise-cuda-graph 替换为
v0.5.19 中它们所映射的 --cuda-graph-max-bs-decode 与
--cuda-graph-backend-prefill=disabled。

Thanks for the contribution!

  • Review: If this PR changes files owned by someone other than a repository admin or @SemiAnalysisAI/core, ask one eligible CODEOWNER to complete the latest PR_REVIEW_CHECKLIST.md before contacting a core maintainer on Slack. Follow the template exactly, including As a PR reviewer and CODEOWNER, I have reviewed this and have, so sign-off verification triggers.
  • PR verification: Sweeps run only when the PR appends an inferencex-e2e/perf-changelog.yaml entry and carries exactly one primary label: full-sweep-fail-fast (strongly recommended; canary plus per-matrix fail-fast), full-sweep-enabled (canary; matrix jobs continue after a failure), or non-canary-full-sweep-enabled (no canary or fail-fast). The modifiers all-evals, evals-only, and agentx-fast require a primary label. On fork PRs, a maintainer applies the label. See sweep labels and reuse.
  • After merging: PR authors must ensure all GitHub Actions jobs pass. Transient failures often pass on rerun; see how to rerun failed jobs.

感谢你的贡献!

  • **审阅:**如果 PR 修改的文件归属于仓库管理员及 @SemiAnalysisAI/core 之外的 CODEOWNER,请先联系一位有资格的 CODEOWNER 填写最新的 PR_REVIEW_CHECKLIST.md,再通过 Slack 联系核心维护者。必须严格遵循模板,并保留 As a PR reviewer and CODEOWNER, I have reviewed this and have,才能触发签核验证。
  • **PR 验证:**只有当 PR 在 inferencex-e2e/perf-changelog.yaml 末尾追加了条目,并且恰好带有一个主标签时,才会运行扫描:full-sweep-fail-fast(强烈推荐;canary 加逐矩阵 fail-fast)、full-sweep-enabled(有 canary;矩阵任务在失败后继续运行)或 non-canary-full-sweep-enabled(无 canary,也无 fail-fast)。修饰标签 all-evals、evals-only 和 agentx-fast 必须与主标签一起使用。fork PR 的标签由维护者添加。参见扫描标签与复用。
  • **合并后:**PR 作者必须确保所有 GitHub Actions 任务通过。临时性失败通常可以通过重新运行恢复;参见重新运行失败任务的说明。

Change: On measured ref 6958af0, pin v0.5.21-cu130 by digest (revision e00930c = tag v0.5.21) and rename removed --cuda-graph-max-bs and --disable-piecewise-cuda-graph to their v0.5.19 alias targets --cuda-graph-max-bs-decode and --cuda-graph-backend-prefill=disabled (v0.5.19, v0.5.21); jobs failed before engine launch because staged weights /scratch/models/DeepSeek-R1-0528-NVFP4-v2 were missing, and fail-fast cancelled c1.

**变更:**在实测提交 6958af0 上,按摘要固定 v0.5.21-cu130(修订 e00930c 即 v0.5.21 标签),并将已移除的 --cuda-graph-max-bs 与 --disable-piecewise-cuda-graph 改为其 v0.5.19 别名目标 --cuda-graph-max-bs-decode 与 --cuda-graph-backend-prefill=disabled;任务因缺少预置权重 /scratch/models/DeepSeek-R1-0528-NVFP4-v2 在引擎启动前失败,c1 被 fail-fast 取消。实测数值及异常说明见上表。
**下一步:**以就绪阻塞结束,待 b200-nscale 节点本地 scratch 上的 DeepSeek-R1-0528 预置权重恢复后再试。
