+For any model listed under [Supported Models on CPU](../../models/hardware_supported_models/cpu.md), optimized runtime configurations are provided in the vLLM Benchmark Suite’s CPU test cases, defined in cpu test cases as serving-tests-cpu.json. Full test cases for Text-only models, Multi-Modal models and Embedded models are in cpu Text-Only test cases as serving-tests-cpu-text.json, cpu Multi-Modal test cases as serving-tests-cpu-multimodal.json and cpu Embedded test cases as serving-tests-cpu-embed.json.  
 For details on how these optimized configurations are determined, see: [performance-benchmark-details](../../../.buildkite/performance-benchmarks/README.md#performance-benchmark-details).
 To benchmark the supported models using these optimized settings, follow the steps in [running vLLM Benchmark Suite manually](../../benchmarking/dashboard.md#manually-trigger-the-benchmark) and run the Benchmark Suite on a CPU environment.

 , which publishes default-model CPU results produced using the same Benchmark Suite.
 
+#### Dry-Run
+
+For users only need to get the optimized runtime configurations without running benchmark, a Dry-Run mode is provided.
+By passing an environment variable DRY_RUN=1 with run-performance-benchmarks.sh,

 ### How to decide `VLLM_CPU_OMP_THREADS_BIND`?
 
 - Default `auto` thread-binding is recommended for most cases. Ideally, each OpenMP thread will be bound to a dedicated physical core respectively, threads of each rank will be bound to the same NUMA node respectively, and 1 CPU per rank will be reserved for other vLLM components when `world_size > 1`. If you have any performance problems or unexpected binding behaviours, please try to bind threads as following.
