-C-Eval benchmark test allows users to test on [C-Eval](https://cevalbenchmark.com) datasets, which is a multi-level multi-discipline chinese evaluation suite for foundation models. It consists of 13948 multi-choice questions spanning 52 diverse disciplines and four difficulty levels. Please check [paper](https://arxiv.org/abs/2305.08322) and [github repo](https://github.com/hkust-nlp/ceval) for more information.

+
+### Multi-GPU Environment
+
+#### 1. Prepare Environment
+
+1. **Set Docker Image and Container Name**:
+   ```bash
+   export DOCKER_IMAGE=intelanalytics/ipex-llm-serving-xpu:latest
+   export CONTAINER_NAME=ceval-benchmark
+   ```
+
+2. **Start Docker Container**:
+   ```bash
+   docker run -td \
+         --privileged \
+         --net=host \
+         --device=/dev/dri \
+         --name=$CONTAINER_NAME \
+         -v /home/intel/LLM:/llm/models/ \
+         -e no_proxy=localhost,127.0.0.1 \
+         -e http_proxy=$HTTP_PROXY \
+         -e https_proxy=$HTTPS_PROXY \
+         --shm-size="16g" \
+         $DOCKER_IMAGE
+   ```
+
+3. **Enter the Container**:
+   ```bash
+   docker exec -it $CONTAINER_NAME bash
+   ```
+
+#### 2. Configure `lm-evaluation-harness`
+
+1. **Clone the Repository**:
+   ```bash
+   git clone https://github.com/EleutherAI/lm-evaluation-harness
+   cd lm-evaluation-harness
+   ```
+
+2. **Update Multi-GPU Support File**:
+   Update `lm_eval/models/vllm_causallms.py` based on the following link:
+   [Update Multi-GPU Support File](https://github.com/EleutherAI/lm-evaluation-harness/compare/main...liu-shaojun:lm-evaluation-harness:multi-arc?expand=1)
+
+3. **Install Dependencies**:
+   ```bash
+   pip install -e .
+   ```
+
+#### 3. Configure Environment Variables
+
+Set environment variables required for multi-GPU execution:
+```bash
+export CCL_WORKER_COUNT=2
+export CCL_ATL_TRANSPORT=ofi
+export CCL_ZE_IPC_EXCHANGE=sockets
+export CCL_ATL_SHM=1
+export CCL_SAME_STREAM=1
+export CCL_BLOCKING_WAIT=0
+
+export SYCL_CACHE_PERSISTENT=1
+export FI_PROVIDER=shm
+export USE_XETLA=OFF
+export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=2
+export TORCH_LLM_ALLREDUCE=0
+```
+
+Load Intel OneCCL environment variables:
+```bash
+source /opt/intel/1ccl-wks/setvars.sh
+```
+
+#### 4. Run Evaluation
+
+Use the following command to run the C-Eval benchmark:
+```bash
+lm_eval --model vllm \
+  --model_args pretrained=/llm/models/CodeLlama-34b/,dtype=float16,max_model_len=2048,device=xpu,load_in_low_bit=fp8,tensor_parallel_size=4,distributed_executor_backend="ray",gpu_memory_utilization=0.90,trust_remote_code=True \
+  --tasks ceval-valid \
+  --batch_size 2 \
+  --num_fewshot 0 \
+  --output_path c-eval-result
+```
+
+#### 5. Notes
+
+- **Model and Parameter Adjustments**:
+  - **`pretrained`**: Replace with the desired model path, e.g., `/llm/models/CodeLlama-7b/`.
+  - **`load_in_low_bit`**: Set to `fp8` or other precision options based on hardware and task requirements.
+  - **`tensor_parallel_size`**: Adjust based on the number of GPUs and memory. Recommended to match the GPU count.
+  - **`batch_size`**: Increase to accelerate testing, but ensure it does not cause OOM errors. Recommended values are `2` or `3`.
+  - **`num_fewshot`**: Specify the number of few-shot examples. Default is `0`. Increasing this value can improve model contextual understanding but may significantly increase input length and runtime.
+
+- **Logging**:
+  To log both to the console and a file, use:
+  ```bash
+  lm_eval --model vllm ... | tee c-eval.log
+  ```
+
+- **Container Debugging**:
+  Ensure the paths for the model and tasks are correctly set, e.g., check if `/llm/models/` is properly mounted in the container.
+
+---
+
+By following the above steps, you can successfully run the C-Eval benchmark in both single-GPU and multi-GPU environments.
