Generally most InferenceX submissions don't need to add changes to the infx package. On the off chance they do, generally the diff is small. Please prompt your agent to clean your PR to keep your diff to only necessary & minimal changes too. We have an increased code quality bar for changes to the infx package. 中文大多数 InferenceX 提交通常不需要修改 infx 包。即使确实需要，改动通常也很小。请让你的 agent 清理 PR，使改动只包含必要且最小的内容。infx 包的改动有更高的代码质量要求。 |

Summary
Multinode points on clusters without a DCGM exporter port now measure GPU power with the cluster's own exporter. Only mi355x-amds changes: its disaggregated and TileRT points get best-effort AMD GPU and RAPL CPU power.
runners.yamlnow rejects RAPL on shared nodes. No config key changes, so no changelog entry.Testing: Unit tests pass; 19 of 1388 rendered recipes change, all mi355x multinode. MI355X proof has valid GPU and CPU power. TP4-prefill variants idle some GPUs, so their power is invalid; results stay.
Depends on: #3670.

Do this only once there is a final full sweep that is all green with evals passing, since after this comment the primary sweep label will no longer automatically kick off new sweeps. Remove and re-add the primary sweep label to force a new sweep.中文
没有 DCGM exporter 端口的集群，多节点点现在用集群自带的 exporter 采集 GPU 功耗。目前只有 mi355x-amds 受影响：它的 disagg 和 TileRT 点默认采集 AMD GPU 与 RAPL CPU 功耗（best-effort）。
runners.yaml现在拒绝在共享节点上配置 RAPL。没有配置 key 变化，因此不新增 changelog 条目。测试： 单元测试通过；1388 个渲染出的 recipe 中只有 19 个 mi355x 多节点 recipe 变化。MI355X 验证 run 的 GPU 功耗和 RAPL CPU 功耗均有效。TP4 prefill 变体有空闲 GPU，功耗会判为无效，但基准测试结果保留。
