Run llama.cpp with IPEX-LLM on Intel GPU#
ggerganov/llama.cpp prvoides fast LLM inference in in pure C++ across a variety of hardware; you can now use the C++ interface of ipex-llm as an accelerated backend for llama.cpp running on Intel GPU (e.g., local PC with iGPU, discrete GPU such as Arc, Flex and Max).
See the demo of running LLaMA2-7B on Intel Arc GPU below.
Quick Start#
This quickstart guide walks you through installing and running llama.cpp with ipex-llm.
0 Prerequisites#
IPEX-LLM’s support for llama.cpp now is available for Linux system and Windows system.
Linux#
For Linux system, we recommend Ubuntu 20.04 or later (Ubuntu 22.04 is preferred).
Visit the Install IPEX-LLM on Linux with Intel GPU, follow Install Intel GPU Driver and Install oneAPI to install GPU driver and Intel® oneAPI Base Toolkit 2024.0.
Windows#
Visit the Install IPEX-LLM on Windows with Intel GPU Guide, and follow Install Prerequisites to install Visual Studio 2022 Community Edition, latest GPU driver and Intel® oneAPI Base Toolkit 2024.0.
Note: IPEX-LLM backend only supports the more recent GPU drivers. Please make sure your GPU driver version is equal or newer than 31.0.101.5333, otherwise you might find gibberish output.
1 Install IPEX-LLM for llama.cpp#
To use llama.cpp with IPEX-LLM, first ensure that ipex-llm[cpp] is installed.
conda create -n llm-cpp python=3.11
conda activate llm-cpp
pip install --pre --upgrade ipex-llm[cpp]
After the installation, you should have created a conda environment, named llm-cpp for instance, for running llama.cpp commands with IPEX-LLM.
2 Setup for running llama.cpp#
First you should create a directory to use llama.cpp, for instance, use following command to create a llama-cpp directory and enter it.
mkdir llama-cpp
cd llama-cpp
Initialize llama.cpp with IPEX-LLM#
Then you can use following command to initialize llama.cpp with IPEX-LLM:
init-llama-cpp
After init-llama-cpp, you should see many soft links of llama.cpp’s executable files and a convert.py in current directory.
Please run the following command with administrator privilege in Anaconda Prompt.
init-llama-cpp.bat
After init-llama-cpp.bat, you should see many soft links of llama.cpp’s executable files and a convert.py in current directory.
Note
init-llama-cpp will create soft links of llama.cpp’s executable files to current directory, if you want to use these executable files in other places, don’t forget to run above commands again.
Now you can use these executable files by standard llama.cpp’s usage.
3 Example: Running community GGUF models with IPEX-LLM#
Here we provide a simple example to show how to run a community GGUF model with IPEX-LLM.
Set Environment Variables#
Configure oneAPI variables by running the following command:
source /opt/intel/oneapi/setvars.sh
This is a required step for APT or offline installed oneAPI. Skip this step for PIP-installed oneAPI.
call "C:\Program Files (x86)\Intel\oneAPI\setvars.bat"
Model Download#
Before running, you should download or copy community GGUF model to your current directory. For instance, mistral-7b-instruct-v0.1.Q4_K_M.gguf of Mistral-7B-Instruct-v0.1-GGUF.
Run the quantized model#
./main -m mistral-7b-instruct-v0.1.Q4_K_M.gguf -n 32 --prompt "Once upon a time, there existed a little girl who liked to have adventures. She wanted to go to places and meet new people, and have fun" -t 8 -e -ngl 33 --color
For more details about meaning of each parameter, you can use ./main -h.
main.exe -m mistral-7b-instruct-v0.1.Q4_K_M.gguf -n 32 --prompt "Once upon a time, there existed a little girl who liked to have adventures. She wanted to go to places and meet new people, and have fun" -t 8 -e -ngl 33 --color
For more details about meaning of each parameter, you can use main.exe -h.

Troubleshooting#
Fail to quantize model#
If you encounter main: failed to quantize model from xxx, please make sure you have created related output directory.
Program hang during model loading#
If your program hang after llm_load_tensors: SYCL_Host buffer size = xx.xx MiB, you can add --no-mmap in your command.
How to set -ngl parameter#
-ngl means the number of layers to store in VRAM. If your VRAM is enough, we recommend putting all layers on GPU, you can just set -ngl to a large number like 999 to achieve this goal.
