ggerganov/llama.cpp prvoides fast LLM inference 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.

Note
ipex-llm[cpp]==2.2.0b20240826 is consistent with 62bfef5 of llama.cpp.
Our latest version is consistent with a1631e5 of llama.cpp.
Note
Starting from ipex-llm[cpp]==2.2.0b20240912, oneAPI dependency of ipex-llm[cpp] on Windows will switch from 2024.0.0 to 2024.2.1 .
For this update, it's necessary to create a new conda environment to install the latest version on Windows. If you directly upgrade to ipex-llm[cpp]>=2.2.0b20240912 in the previous cpp conda environment, you may encounter the error Can't find sycl7.dll.
- Prerequisites
- Install IPEX-LLM for llama.cpp
- Setup for running llama.cpp
- Example: Running community GGUF models with IPEX-LLM
- Troubleshooting
This quickstart guide walks you through installing and running llama.cpp with ipex-llm.
IPEX-LLM's support for llama.cpp now is available for Linux system and Windows system.
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.
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 to update your GPU driver; otherwise, you might encounter gibberish output.
To use llama.cpp with IPEX-LLM, first ensure that ipex-llm[cpp] is installed.
-
For Linux users:
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.
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.
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-cppThen you can use following command to initialize llama.cpp with IPEX-LLM:
-
For Linux users:
init-llama-cpp
After
init-llama-cpp, you should see many soft links ofllama.cpp's executable files and aconvert.pyin current directory. -
For Windows users:
Please run the following command with administrator privilege in Miniforge Prompt.
init-llama-cpp.bat
After
init-llama-cpp.bat, you should see many soft links ofllama.cpp's executable files and aconvert.pyin 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.
To use GPU acceleration, several environment variables are required or recommended before running llama.cpp.
-
For Linux users:
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.
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.
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.
Here we provide a simple example to show how to run a community GGUF model with IPEX-LLM.
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.
-
For Linux users:
./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 --colorNote:
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.
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
Note:
For more details about meaning of each parameter, you can use
./llama-cli -h.

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.
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.
If you encounter main: prompt is too long (xxx tokens, max xxx), please increase the -c parameter to set a larger size of context.
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 for more details.
If you encounter main: failed to quantize model from xxx, please make sure you have created related output directory.
If your program hang after llm_load_tensors: SYCL_Host buffer size = xx.xx MiB, you can add --no-mmap in your command.
-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.
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.
If you run the llama.cpp program on Windows and find that your program crashes or outputs abnormally when accepting Chinese prompts, you can open Region->Administrative->Change System locale.., check Beta: Use Unicode UTF-8 for worldwide language support option and then restart your computer.
For detailed instructions on how to do this, see this issue.
If you meet System Error: sycl7.dll not found on Windows or you meet similar error on Linux, please check:
- if you have installed conda and if you are in the right conda environment which has pip installed oneapi dependencies on Windows
- if you have executed
source /opt/intel/oneapi/setvars.shon Linux
If you meet garbage output, please check if your GPU driver version is >= 31.0.101.5522. If not, please follow the instructions in this section to update your GPU driver.
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.
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.
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.
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 to see if it helps.
