[ggerganov/llama.cpp](https://github.com/ggerganov/llama.cpp) provides fast LLM inference in pure C++ across a variety of hardware; you can now use the C++ interface of [`ipex-llm`](https://github.com/intel-analytics/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)*.
|
|
|
|
> [!Important]
|
|
> You may use [llama.cpp Portable Zip](./llamacpp_portable_zip_gpu_quickstart.md) to directly run llama.cpp on Intel GPU with ipex-llm (***without the need of manual installations***).
|
|
|
|
> [!NOTE]
|
|
> For installation on Intel Arc B-Series GPU (such as **B580**), please refer to this [guide](./bmg_quickstart.md).
|
|
|
|
> [!NOTE]
|
|
> Our latest version is consistent with [d7cfe1f](https://github.com/ggml-org/llama.cpp/commit/d7cfe1ffe0f435d0048a6058d529daf76e072d9c) of llama.cpp.

|
## 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](./install_linux_gpu.md), follow [Install Intel GPU Driver](./install_linux_gpu.md#install-gpu-driver) to install GPU driver for Ubuntu 22.04 (or follow the [Intel client GPU driver installation guide](https://dgpu-docs.intel.com/driver/client/overview.html) for a higher version of Ubuntu). And follow the guide [here](https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html?packages=oneapi-toolkit&oneapi-toolkit-os=linux&oneapi-lin=offline) to install Intel® oneAPI Base Toolkit 2025.0.
|
|
|
|
#### Windows (Optional)
|
|
|
|
Please make sure your GPU driver version is equal or newer than `31.0.101.5522`. If it is not, follow the instructions in [this section](./install_windows_gpu.md#optional-update-gpu-driver) to update your GPU driver; otherwise, you might encounter gibberish output.
|
|
|
|
### 1. Install IPEX-LLM for llama.cpp
|
|
|
|
To use `llama.cpp` with IPEX-LLM, first ensure that `ipex-llm[cpp]` is installed.
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
conda create -n llm-cpp python=3.11
|
|
conda activate llm-cpp
|
|
pip install --pre --upgrade ipex-llm[cpp]
|
|
```
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command in Miniforge Prompt.
|
|
|
|
```cmd
|
|
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.
|
|
```cmd
|
|
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:
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
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.
|
|
|
|
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command with **administrator privilege in Miniforge Prompt**.
|
|
|
|
```cmd
|
|
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.
|
|
|
|
|
|
|
|
> [!TIP]
|
|
> `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.
|
|
|
|
> [!NOTE]
|
|
> If you have installed higher version `ipex-llm[cpp]` and want to upgrade your binary file, don't forget to remove old binary files first and initialize again with `init-llama-cpp` or `init-llama-cpp.bat`.
|
|
|
|
**Now you can use these executable files by standard llama.cpp's usage.**
|
|
|
|
#### Runtime Configuration
|
|
|
|
To use GPU acceleration, several environment variables are required or recommended before running `llama.cpp`.
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
source /opt/intel/oneapi/setvars.sh
|
|
export SYCL_CACHE_PERSISTENT=1
|
|
# [optional] under most circumstances, the following environment variable may improve performance, but sometimes this may also cause performance degradation
|
|
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
|
|
# [optional] if you want to run on single GPU, use below command to limit GPU may improve performance
|
|
export ONEAPI_DEVICE_SELECTOR=level_zero:0
|
|
```
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command in Miniforge Prompt.
|
|
|
|
```cmd
|
|
set SYCL_CACHE_PERSISTENT=1
|
|
rem under most circumstances, the following environment variable may improve performance, but sometimes this may also cause performance degradation
|
|
set SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
|
|
```
|
|
|
|
> [!TIP]
|
|
> When your machine has multi GPUs and you want to run on one of them, you need to set `ONEAPI_DEVICE_SELECTOR=level_zero:[gpu_id]`, here `[gpu_id]` varies based on your requirement. For more details, you can refer to [this section](../Overview/KeyFeatures/multi_gpus_selection.md#2-oneapi-device-selector).
|
|
|
|
> [!NOTE]
|
|
> The environment variable `SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS` determines the usage of immediate command lists for task submission to the GPU. While this mode typically enhances performance, exceptions may occur. Please consider experimenting with and without this environment variable for best performance. For more details, you can refer to [this article](https://www.intel.com/content/www/us/en/developer/articles/guide/level-zero-immediate-command-lists.html).
|
|
|
|
### 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.
|
|
|
|
#### 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](https://huggingface.co/TheBloke/Mistral-7B-Instruct-v0.1-GGUF/tree/main).
|
|
|
|
#### Run the quantized model
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
./llama-cli -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" -c 1024 -t 8 -e -ngl 99 --color -no-cnv
|
|
```
|
|
|
|
> **Note**:
|
|
>
|
|
> For more details about meaning of each parameter, you can use `./llama-cli -h`.
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command in Miniforge Prompt.
|
|
|
|
```cmd
|
|
llama-cli -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" -c 1024 -t 8 -e -ngl 99 --color -no-cnv
|
|
```
|
|
|
|
> **Note**:
|
|
>
|
|
> For more details about meaning of each parameter, you can use `./llama-cli -h`.
|
|
|

### Troubleshooting
|
|
|
|
#### 1. Unable to run the initialization script
|
|
If you are unable to run `init-llama-cpp.bat`, please make sure you have installed `ipex-llm[cpp]` in your conda environment. If you have installed it, please check if you have activated the correct conda environment. Also, if you are using Windows, please make sure you have run the script with administrator privilege in prompt terminal.
|
|
|
|
#### 2. `DeviceList is empty. -30 (PI_ERROR_INVALID_VALUE)` error
|
|
On Linux, this error happens when devices starting with `[ext_oneapi_level_zero]` are not found. Please make sure you have installed level-zero, and have sourced `/opt/intel/oneapi/setvars.sh` before running the command.
|
|
|
|
#### 3. `Prompt is too long` error
|
|
If you encounter `main: prompt is too long (xxx tokens, max xxx)`, please increase the `-c` parameter to set a larger size of context.
|
|
|
|
#### 4. `gemm: cannot allocate memory on host` error / `could not create an engine` error
|
|
If you meet `oneapi::mkl::oneapi::mkl::blas::gemm: cannot allocate memory on host` error, or `could not create an engine` on Linux, this is probably caused by pip installed OneAPI dependencies. You should prevent installing like `pip install dpcpp-cpp-rt==2024.0.2 mkl-dpcpp==2024.0.0 onednn==2024.0.0`, and instead use `apt` to install on Linux. Please refer to [this guide](./install_linux_gpu.md) for more details.

|
#### 5. Fail to quantize model
|
|
If you encounter `main: failed to quantize model from xxx`, please make sure you have created related output directory.
|
|
|
|
#### 6. 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.
|
|
|
|
#### 7. 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.
|
|
|
|
If `-ngl` is set to 0, it means that the entire model will run on CPU. If `-ngl` is set to greater than 0 and less than model layers, then it's mixed GPU + CPU scenario.
|
|
|
|
#### 8. How to specificy GPU
|
|
If your machine has multi GPUs, `llama.cpp` will default use all GPUs which may slow down your inference for model which can run on single GPU. You can add `-sm none` in your command to use one GPU only.
|
|
|
|
Also, you can use `ONEAPI_DEVICE_SELECTOR=level_zero:[gpu_id]` to select device before excuting your command, more details can refer to [here](../Overview/KeyFeatures/multi_gpus_selection.md#2-oneapi-device-selector).
|
|
|
|
#### 9. Program crash with Chinese prompt
|
|
If you run the llama.cpp program on Windows and find that your program crashes or outputs abnormally when accepting Chinese prompts, you can search for `region` in the Windows search bar and go to `Region->Administrative->Change System locale..`, tick `Beta: Use Unicode UTF-8 for worldwide language support` option and then restart your computer.

#### 10. sycl7.dll not found error
|
|
If you meet `System Error: sycl7.dll not found` on Windows or you meet similar error on Linux, please check:
|
|
|
|
1. if you have installed conda and if you are in the right conda environment which has pip installed oneapi dependencies on Windows
|
|
2. if you have executed `source /opt/intel/oneapi/setvars.sh` on Linux
|
|
|
|
#### 11. Check driver first when you meet garbage output on Windows
|
|
If you meet garbage output on Windows, please check if your GPU driver version is >= [31.0.101.5522](https://www.intel.cn/content/www/cn/zh/download/785597/823163/intel-arc-iris-xe-graphics-windows.html). If not, please follow the instructions in [this section](./install_windows_gpu.md#optional-update-gpu-driver) to update your GPU driver.

|
|
|
#### 12. Why my program can't find sycl device
|
|
If you meet `GGML_ASSERT: C:/Users/Administrator/actions-runner/cpp-release/_work/llm.cpp/llm.cpp/llama-cpp-bigdl/ggml-sycl.cpp:18283: main_gpu_id<g_all_sycl_device_count` error or similar error, and you find nothing is output when using `ls-sycl-device`, this is because llama.cpp cannot find the sycl device. On some laptops, the installation of the ARC driver may lead to a forced installation of `OpenCL, OpenGL, and Vulkan Compatibility Pack` by Microsoft, which inadvertently blocks the system from locating sycl devices. This issue can be resolved by manually uninstalling it in Microsoft store.
|
|
|
|
#### 13. Core dump when having both integrated and dedicated graphics
|
|
If you have both integrated and dedicated graphics displayed in your llama.cpp's device log and don't specify which device to use, it will cause a core dump. In such case, you may need to specify `export ONEAPI_DEVICE_SELECTOR=level_zero:0` before running `llama-cli`.
|
|
|
|
#### 14. `Native API failed` error
|
|
On latest version of `ipex-llm`, you might come across `native API failed` error with certain models without the `-c` parameter. Simply adding `-c xx` would resolve this problem.
|
|
|
|
#### 15. `signal: bus error (core dumped)` error
|
|
If you meet this error, please check your Linux kernel version first. You may encounter this issue on higher kernel versions (like kernel 6.15). You can also refer to [this issue](https://github.com/intel-analytics/ipex-llm/issues/10955) to see if it helps.
|
|
|
|
#### 16. `backend buffer base cannot be NULL` error
|
|
If you meet `ggml-backend.c:96: GGML_ASSERT(base != NULL && "backend buffer base cannot be NULL") failed`, simply adding `-c xx` parameter during inference, for example `-c 1024` would resolve this problem.
