Thanks for the contribution! Please reach out to respective companies' CODEOWNER to fill in the latest PR_REVIEW_CHECKLIST.md before pinging core maintainer on Slack for review. In order for the signoff PR check bot to trigger, you must follow the PR_REVIEW_CHECKLIST.md template correctly, including the phrase As a PR reviewer and CODEOWNER, I have reviewed this and have.

For PR verification, add the full-sweep-fail-fast label (strongly recommended) to this PR — the benchmark sweep only runs on labeled PRs. Use full-sweep-enabled only if you need matrix jobs to keep running past a failure.

PR authors are responsible for ensuring that after merging, all GitHub Action jobs fully pass. A lot of the time, failures are just flakes and simply re-running the failed jobs will fix it. See GitHub's docs on re-running failed jobs

感谢你的贡献！请联系相应公司的 CODEOWNER 填写最新的 PR_REVIEW_CHECKLIST.md，然后再在 Slack 上联系核心维护者进行审阅。为了触发 signoff PR 检查机器人，你必须正确遵循 PR_REVIEW_CHECKLIST.md 模板，包括保留英文语句 As a PR reviewer and CODEOWNER, I have reviewed this and have。

如需进行 PR 验证，请为此 PR 添加 full-sweep-fail-fast 标签（强烈推荐）— 基准测试 sweep 仅在带有标签的 PR 上运行。仅当需要矩阵任务在失败后继续运行时才使用 full-sweep-enabled。

PR 作者有责任确保合并后所有 GitHub Action 任务完全通过。 很多时候失败只是偶发抖动（flake），重新运行失败的任务即可解决。参见 GitHub 关于重新运行失败任务的文档

Review: KIMI fp4 MI355 recipe update

• Gather context and diff against origin/main
• Review configs/amd-master.yaml changes
• Review benchmark script changes
• Validate perf-changelog.yaml entry against the changelog gate
• Post inline comments

Findings

1 blocking issue (inline comment): the new perf-changelog.yaml entry is indented 2 extra spaces ( - config-keys: instead of - config-keys: at column 0). This is invalid YAML — utils/validate_perf_changelog.py will fail to parse the file (and its append-format check would reject it anyway), so the changelog gate in run-sweep.yml fails and the sweep for kimik2.5-fp4-mi355x-atom never triggers. The suggestion in the inline comment fixes the indentation and also replaces the placeholder "TODO & update image" description with one documenting the actual changes.

1 warning (inline comment): --scheduler-delay-factor 1 was appended onto the -tp $TP line in the benchmark script; repo style requires one server-launch argument per line.

Notes

• Both issues from the previous review are resolved: the image is now the org-owned rocm/atom-dev:nightly_202607091539 (no longer a personal namespace), and a perf-changelog.yaml entry was added (correctly appended at the end).
• I could not verify externally that the rocm/atom-dev:nightly_202607091539 tag is actually published on Docker Hub (the timestamp suggests it was pushed today, 2026-07-09 15:39) — please confirm it's public before merging, otherwise the sweep will fail at image pull.
• The TP8 search-space narrowing to a single concurrency point (conc 4) for both scenarios and the new AITER/ATOM env vars look intentional; the EP flag remains correctly conditional on EP_SIZE.

Fix the changelog entry →
