+# Intel GPU Support for KTransformers (Beta)
+
+## Introduction
+
+### Overview
+We are excited to introduce **Intel GPU support** in KTransformers (Beta release). This implementation has been tested and developed using Intel Xeon Scalable processors and Intel Arc GPU's (such as A770 and B580).
+
+## Installation Guide
+
+### 1. Install Intel GPU Driver
+Begin by installing the GPU drivers for your Intel GPU:
+- [Official GPU Installation Guide for Intel GPUs](https://dgpu-docs.intel.com/driver/overview.html)
+
+> [!Important]
+> Ensure that **Resizable BAR** is enabled in your system's BIOS before proceeding. This is essential for optimal GPU performance and to avoid potential issues such as `Bus error (core dumped)`. For detailed steps, please refer to the official guidance [here](https://www.intel.com/content/www/us/en/support/articles/000090831/graphics.html).
+
+### 2. Set Up Conda Environment
+We recommend using Miniconda3/Anaconda3 for environment management:
+
+```bash
+# Download Miniconda
+wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
+
+# Create environment
+conda create --name ktransformers python=3.11
+conda activate ktransformers
+
+# Install required libraries
+conda install -c conda-forge libstdcxx-ng
+
+# Verify GLIBCXX version (should include 3.4.32)
+strings ~/anaconda3/envs/ktransformers/lib/libstdc++.so.6 | grep GLIBCXX
+```
+
+> **Note:** Adjust the Anaconda path if your installation directory differs from `~/anaconda3`
+
+### 3. Install PyTorch and IPEX-LLM
+Install PyTorch with XPU backend support and [IPEX-LLM](https://github.com/intel/ipex-llm):
+
+```bash
+pip install --pre --upgrade ipex-llm[xpu_2.6] --extra-index-url https://download.pytorch.org/whl/xpu
+pip uninstall torch torchvision torchaudio
+pip install torch==2.7+xpu torchvision torchaudio --index-url https://download.pytorch.org/whl/test/xpu # install torch2.7
+pip install packaging ninja cpufeature numpy
+pip uninstall intel-opencl-rt dpcpp-cpp-rt
+```
+
+### 4. Build ktransformers
+
+```bash
+# Clone repository
+git clone https://github.com/kvcache-ai/ktransformers.git
+cd ktransformers
+git submodule update --init
+
+# Install dependencies
+bash install.sh
+pip uninstall triton pytorch-triton-xpu
+pip install pytorch-triton-xpu==3.3.0 --extra-index-url https://download.pytorch.org/whl/xpu # to avoid potential triton import error
+```
+
+## Running DeepSeek-R1 Models
+
+### Configuration for 16B VRAM GPUs
+Use our optimized configuration for constrained VRAM:
+
+```bash
+export SYCL_CACHE_PERSISTENT=1
+export ONEAPI_DEVICE_SELECTOR=level_zero:0
+export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
+
+python ktransformers/local_chat.py \
+  --model_path deepseek-ai/DeepSeek-R1 \
+  --gguf_path <path_to_gguf_files> \
+  --optimize_config_path ktransformers/optimize/optimize_rules/xpu/DeepSeek-V3-Chat.yaml \
+  --cpu_infer <cpu_cores + 1> \
+  --device xpu \
+  --max_new_tokens 200
+```
+
+## Known Limitations
+- Serving function is not supported on Intel GPU platform for now
+
+## Troubleshooting
+1. Best Known Config (BKC) to obtain best performance
+
+To obtain best performance on Intel GPU platform, we recommand to lock GPU frequency and set CPU to performance mode by below settings.
+```bash
+echo "performance" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
+echo 0 | sudo tee /sys/devices/system/cpu/cpu*/power/energy_perf_bias
+# 2400 is max frequency for Arc A770
+sudo xpu-smi config -d 0 -t 0 --frequencyrange 2400,2400
+# 2850 is max frequency for Arc B580
+# sudo xpu-smi config -d 0 -t 0 --frequencyrange 2850,2850
+```
+
+2. Runtime error like `xpu/sycl/TensorCompareKernels.cpp:163: xxx. Aborted (core dumped)`
+
+This error is mostly realted to GPU driver. If you meet such error, you could update your `intel-level-zero-gpu` to `1.3.29735.27-914~22.04` (which is a verified version by us) by below command.
+```bash
+wget -qO - https://repositories.intel.com/gpu/intel-graphics.key | \
+sudo gpg --dearmor --output /usr/share/keyrings/intel-graphics.gpg
+echo "deb [arch=amd64,i386 signed-by=/usr/share/keyrings/intel-graphics.gpg] https://repositories.intel.com/gpu/ubuntu jammy client" | \
+sudo tee /etc/apt/sources.list.d/intel-gpu-jammy.list
+sudo apt update
+# or sudo apt update --allow-insecure-repositories
+sudo apt install intel-level-zero-gpu=1.3.29735.27-914~22.04
+```
+
+3. `ImportError: cannot import name 'intel' from 'triton._C.libtriton'`
+
+Installing Triton causes pytorch-triton-xpu to stop working. You can resolve the issue with following command:
+```bash
+pip uninstall triton pytorch-triton-xpu
+# Reinstall correct version of pytorch-triton-xpu
+pip install pytorch-triton-xpu==3.3.0 --index-url  https://download.pytorch.org/whl/xpu
+```
