#### `--master-port` / `--head-port` Parameter
Added `--master-port` (synonym: `--head-port`) to both `launch-cluster.sh` and `run-recipe.sh` to configure the port used for cluster coordination:
- In **Ray mode**: sets the Ray head node port (previously hardcoded to 6379)
- In **No-Ray mode**: sets the PyTorch distributed `--master-port` passed to vLLM
Default is `29501`.
```bash
./launch-cluster.sh --master-port 29501 --no-ray exec vllm serve ...
./run-recipe.sh qwen3.5-122b-fp8 --no-ray --master-port 29501
