# Run BigDL-LLM on Multiple Intel GPUs in pipeline parallel fashion
|
|
|
|
This example demonstrates how to run BigDL-LLM optimized low-bit model vertically partitioned on two [Intel GPUs](../README.md).
|
|
|
|
## Requirements
|
|
To run this example with BigDL-LLM on Intel GPUs, we have some recommended requirements for your machine, please refer to [here](../README.md#recommended-requirements) for more information. For this particular example, you will need at least two GPUs on your machine.
|
|
|
|
## Example:
|
|
|
|
### 1.1 Install BigDL-LLM
|
|
|
|
```bash
|
|
conda create -n llm python=3.9
|
|
conda activate llm
|
|
# below command will install intel_extension_for_pytorch==2.1.10+xpu as default
|
|
# you can install specific ipex/torch version for your need
|
|
pip install --pre --upgrade bigdl-llm[xpu_2.1] -f https://developer.intel.com/ipex-whl-stable-xpu
|
|
# configures OneAPI environment variables
|
|
source /opt/intel/oneapi/setvars.sh
|
|
|
|
conda install -c conda-forge -y gperftools=2.10 # to enable tcmalloc
|
|
```
|
|
|
|
### 1.2 Build and install patched version of Intel Extension for PyTorch (IPEX)
|
|
|
|
```bash
|
|
conda activate llm
|
|
source /opt/intel/oneapi/setvars.sh
|
|
git clone https://github.com/intel/intel-extension-for-pytorch.git
|
|
cd intel-extension-for-pytorch
|
|
git checkout v2.1.10+xpu
|
|
git submodule update --init --recursive
|
|
git cherry-pick be8ea24078d8a271e53d2946ac533383f7a2aa78
|
|
export USE_AOT_DEVLIST='ats-m150,pvc'
|
|
python setup.py install
|
|
```
|
|
|
|
|
|
> **Important**: IPEX 2.1.10+xpu requires Intel® oneAPI Base Toolkit's version == 2024.0. Please make sure you have installed the correct version.
|
|
|
|
### 2. Run tensor parallel inference on multiple GPUs
|
|
Here, we provide example usages on different models and different hardwares. Please refer to the appropriate script based on your model and device:
|
|
|
|
### 3. Run
|
|
|
|
For optimal performance on Arc, it is recommended to set several environment variables.
|
|
|
|
```bash
|
|
export USE_XETLA=OFF
|
|
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
|
|
```
|
|
|
|
```
|
|
python ./generate.py --repo-id-or-model-path REPO_ID_OR_MODEL_PATH --prompt PROMPT --n-predict N_PREDICT
|
|
```
|
|
|
|
Arguments info:
|
|
- `--repo-id-or-model-path REPO_ID_OR_MODEL_PATH`: argument defining the huggingface repo id for the Llama2 model (e.g. `meta-llama/Llama-2-7b-chat-hf`) to be downloaded, or the path to the huggingface checkpoint folder. It is default to be `'meta-llama/Llama-2-7b-chat-hf'`.
|
|
- `--prompt PROMPT`: argument defining the prompt to be infered (with integrated prompt format for chat). It is default to be `'What is AI?'`.
|
|
- `--n-predict N_PREDICT`: argument defining the max number of tokens to predict. It is default to be `32`.
|
|
|
|
#### Sample Output
|
|
#### [meta-llama/Llama-2-7b-chat-hf](https://huggingface.co/meta-llama/Llama-2-7b-chat-hf)
