Using hipBLAS on Windows

To get hipBLAS in stable-diffusion.cpp working on Windows, go through this guide section by section.

Build Tools for Visual Studio 2022

Skip this step if you already have Build Tools installed.

To install Build Tools, go to Visual Studio Downloads, download Visual Studio 2022 and other Products and run the installer.

CMake

Skip this step if you already have CMake installed: running cmake --version should output cmake version x.y.z.

Download latest Windows x64 Installer from Download | CMake and run it.

ROCm

Skip this step if you already have Build Tools installed.

The validation tools not support on Windows. So you should confirm the Version of ROCM by yourself.

Fortunately, AMD provides complete help documentation, you can use the help documentation to install ROCM

If you encounter an error, if it is AMD ROCm Windows Installation Error 215, don't worry about this error. ROCM has been installed correctly, but the vs studio plugin installation failed, we can ignore it.

Then we must set ROCM as environment variables before running cmake.

Usually if you install according to the official tutorial and do not modify the ROCM path, then there is a high probability that it is here C:\Program Files\AMD\ROCm\5.5\bin

This is what I use to set the clang:

set CC=C:\Program Files\AMD\ROCm\5.5\bin\clang.exe
set CXX=C:\Program Files\AMD\ROCm\5.5\bin\clang++.exe

Ninja

Skip this step if you already have Ninja installed: running ninja --version should output 1.11.1.

Download latest ninja-win.zip from GitHub Releases Page and unzip. Then set as environment variables. I unzipped it in C:\Program Files\ninja, so I set it like this:

set ninja=C:\Program Files\ninja\ninja.exe

Building stable-diffusion.cpp

The thing different from the regular CPU build is -DSD_HIPBLAS=ON , -G "Ninja", -DCMAKE_C_COMPILER=clang, -DCMAKE_CXX_COMPILER=clang++, -DAMDGPU_TARGETS=gfx1100

Notice: check the clang and clang++ information:

clang --version
clang++ --version

If you see like this, we can continue:

clang version 17.0.0 (git@github.amd.com:Compute-Mirrors/llvm-project e3201662d21c48894f2156d302276eb1cf47c7be)
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\AMD\ROCm\5.5\bin

clang version 17.0.0 (git@github.amd.com:Compute-Mirrors/llvm-project e3201662d21c48894f2156d302276eb1cf47c7be)
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\AMD\ROCm\5.5\bin

Notice that the gfx1100 is the GPU architecture of my GPU, you can change it to your GPU architecture. Click here to see your architecture LLVM Target

My GPU is AMD Radeon™ RX 7900 XTX Graphics, so I set it to gfx1100.

option:

mkdir build
cd build
cmake .. -G "Ninja" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DSD_HIPBLAS=ON -DCMAKE_BUILD_TYPE=Release -DAMDGPU_TARGETS=gfx1100
cmake --build . --config Release

If everything went OK, build\bin\sd.exe file should appear.
