bump TRT-LLM to 1.3.0rc20, pin vLLM to v0.22.0, fix max_seq_len for Qwen3.5-4B

What does this PR do?

Type of change: Bug fix, new feature

  • Upgrade TRT-LLM container from 1.3.0rc10 to 1.3.0rc20 across all
    Qwen3-8B, Qwen3-30B-A3B, Kimi-K2.5, and gpt-oss-20b launcher configs.
  • Replace Kimi-K2.5 aarch64-specific vLLM image (v0.22.0-aarch64) with
    the multi-arch v0.22.0 tag, which resolves to amd64/arm64 automatically.
  • Fix Qwen3.5-4B throughput_32k runs: raise max_seq_len from 40960 to
    65536 to accommodate outlier prompts (~46.6K tokens) that caused
    VLLMValidationError and aborted the entire benchmark run.
  • Fix specdec_bench_mtp_vllm.yaml: remove reference to non-existent
    runtime_params_throughput_32k.yaml; use --max_seq_len 65536 instead

Usage

cd Model-Optimizer/tools/launcher
uv run launch.py --yaml examples/Qwen/Qwen3-8B/megatron_lm_ptq_local.yaml hf_local=/mnt/hf-local --yes

Summary by CodeRabbit

  • Improvements
    • Updated launcher example pipelines and the default launcher Slurm container to the newer TensorRT-LLM 1.3.0rc20 image.
    • Updated Kimi-K2.5 workflows to use the multi-architecture vLLM 0.22.0 image (removing prior architecture-specific variants).
    • Increased the Qwen3.5-4B long-context benchmark maximum sequence length to 65,536 tokens and simplified the corresponding throughput configuration.

📝 Walkthrough

Walkthrough

Launcher defaults and example Slurm workflows now use updated TensorRT-LLM and vLLM container images. Qwen3.5-4B throughput benchmarks explicitly set a maximum sequence length of 65536.

vLLM smoke-test containers still float on nightly, not pinned to v0.22.0.

The PR objective states vLLM is being pinned to v0.22.0, but these two workflows still reference the unpinned vllm/vllm-openai:nightly tag for their vLLM smoke-test task, making runs non-reproducible.

  • tools/launcher/examples/Qwen/Qwen3-8B/hf_streaming_dflash.yaml#L93-L93: pin container to vllm/vllm-openai:v0.22.0 (or the multi-arch v0.22.0 image used elsewhere in this PR).
  • tools/launcher/examples/Qwen/Qwen3-8B/hf_streaming_dflash_multi_node.yaml#L96-L96: same fix — pin to vllm/vllm-openai:v0.22.0.

Hi @ChenhanYu @h-guo18, For the vLLM container, can we use the latest tag—i.e., vllm/vllm-openai:latest—so that it always points to the newest vLLM release version? This way, we wouldn’t need to frequently update the YAML file.
