[None][docs] drop ghost enable_overlap_scheduler from trtllm-serve Slurm example

[imitater-dou]

Summary

• The Multi-node Slurm sample in docs/source/commands/trtllm-serve/trtllm-serve.rst wrote pytorch_backend_config.enable_overlap_scheduler: true.
• That nested key is not a TorchLlmArgs field; the live knob is top-level disable_overlap_scheduler (default false, i.e. overlap on). See docs/source/features/overlap-scheduler.md.
• Keep enable_attention_dp: true in the sample YAML; drop the ghost overlap stanza.

Test plan

• Confirmed enable_overlap_scheduler has 0 Python hits on main; only this rst referenced it
• Confirmed disable_overlap_scheduler is the documented/live field in llm_args.py and feature docs
• Diff is a one-line echo rewrite in the Slurm sample

Dev Engineer Review

The Multi-node Slurm example removes the unsupported pytorch_backend_config.enable_overlap_scheduler setting. It retains enable_attention_dp: true and relies on the supported default that enables overlap scheduling.

QA Engineer Review

No test changes.

Per-File QA Perspective

• docs/source/commands/trtllm-serve/trtllm-serve.rst: Verify that the example generates valid configuration and preserves attention data parallelism and default overlap scheduling behavior.

Walkthrough

The Slurm multi-node serving example now writes only enable_attention_dp: true to config.yml. It no longer writes pytorch_backend_config.enable_overlap_scheduler: true.

Changes

Slurm serving configuration

Layer / File(s)	Summary
Update Slurm configuration example docs/source/commands/trtllm-serve/trtllm-serve.rst	The example retains enable_attention_dp: true and removes pytorch_backend_config.enable_overlap_scheduler: true.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 2d731

The Slurm serving example no longer documents an unsupported overlap-scheduler option and continues to enable attention data parallelism. No current merge-readiness risk remains.
