Intel ARC

IPEX and Intel GPUs

GPU Support with IPEX and SD.Next

• Intel ARC Series
• Intel Flex Series
• Intel Max Series

iGPUs are not supported with IPEX, use OpenVINO with iGPUs.

Data Types

BF16 is faster than FP16 with IPEX. FP16 will upcast to FP32 with IPEX.

Errors with iGPU

Disable your iGPU (if any, e.g. UHD or Iris Xe) in the device manager.

Windows Installation

Preparations

• Install Intel GPU Driver.
• Install Intel OneAPI PyTorch GPU Dev
• Install Git.
• Install Python 3.10 or 3.11.
• Open CMD in a folder you want to install SD.Next.

Using SD.Next

Open a CMD Windows and install SD.Next from Github:

git clone https://github.com/vladmandic/automatic
cd automatic

Then run SD.Next:

"C:\Program Files (x86)\Intel\oneAPI\pytorch-gpu-dev-0.5\oneapi-vars.bat"
"C:\Program Files (x86)\Intel\oneAPI\ocloc\2024.2\env\vars.bat" 
.\webui.bat --use-ipex

Note: It will install the necessary libraries at the first run so it will take a while depending on your internet.

Linux and WSL Installation

Install Intel Compute Runtime

Ubuntu

Use Ubuntu 23.04 or newer.

Don't use Linux Kernel 6.8 or 6.9!

https://github.com/intel/compute-runtime/issues/726

Note: Updating kernel is not neccesary for WSL.

Then add the package lists for Intel Level Zero Drivers:

sudo apt update && sudo apt install -y ca-certificates wget gpg
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 && sudo apt upgrade -y

Then install the necessary packages:

sudo apt-get install intel-opencl-icd intel-level-zero-gpu level-zero git python3-pip python3-venv libgl1 libglib2.0-0 libgomp1

Arch Linux

Install the necessary packages for Arch Linux:

pacman -S intel-compute-runtime level-zero-headers level-zero-loader git python-pip python-virtualenv

Using SD.Next

Install SD.Next from Github:

git clone https://github.com/vladmandic/automatic
cd automatic
./webui.sh --use-ipex

Note: It will install the necessary libraries at the first run so it will take a while depending on your internet.
