# Notes

## 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.  

Benchmarks for Intel ARC A770: https://github.com/vladmandic/automatic/wiki/Benchmark#intel-arc


## Data Types
BF16 is faster than FP16 in general.

## Backend:
Diffusers backend is 10%-25% faster than the original backend.

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

## Errors with ipexrun on Linux
If you get random errors at the startup, it's probably from ipexrun.  
Export `DISABLE_IPEXRUN=1` to disable ipexrun.


# Windows Installation
## Preparations
- Install `Intel GPU Driver`.
- Install `Git`.
- Install `Python` 3.10 or 3.11.
- Open CMD in a folder you want to install SD.Next.


## Using SD.Next
Install SD.Next from Github:
```
git clone https://github.com/vladmandic/automatic
```

Then enter into the automatic folder:
```
cd automatic
```

Then start WebUI with this command:
```
.\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 because we will need Linux 6.2 kernel or newer.

Update your kernel to at least Linux 6.2 if you are on older Ubuntu builds.

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 libjemalloc-dev
```


### 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 jemalloc
```




## Using SD.Next
Install SD.Next from Github:
```
git clone https://github.com/vladmandic/automatic
```

Then enter into the automatic folder:
```
cd automatic
```

Then start WebUI with this command:
```
./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.
