How to Compile Stable-Diffusion.cpp on Linux with AMD Instinct Mi60 GPU (Using Vulkan)

Introduction
In this tutorial, I’ll walk you through how to compile and run stable-diffusion.cpp on a Linux system using an AMD Instinct Mi60 32GB HBM2 GPU. We’ll use Vulkan for GPU acceleration since the latest update to Fedora 43 with ROCm 6.4 has unfortunately caused the AMD Instinct Mi60 to no longer be supported by ROCm. I’ll explain the system requirements, how Vulkan differs from ROCm and OpenCL, and show you how to generate images using the v1-5-pruned-emaonly-fp16.safetensors model. I will also provide additional information about resources like my “Learning Python” book and course, and my one-on-one Python tutorials.

System Requirements

To follow along with this tutorial, you will need the following:

• Operating System: Linux (I’m using Fedora 43)
• CPU: A modern x86_64 processor (Intel or AMD)
• GPU: AMD Instinct Mi60 (32GB HBM2)
• Vulkan: Vulkan-compatible GPU driver (since ROCm is no longer supported for Mi60)
• Memory: At least 8GB RAM (16GB recommended)
• Disk Space: 10GB free for installation
• Dependencies:
  • CMake (to build the project)
  • Vulkan SDK
  • Clang++ or GCC (for compilation)
  • libvulkan library
• Model File: Download the v1-5-pruned-emaonly-fp16.safetensors model (for generating images).

Is stable-diffusion.cpp Open Source?

Yes! stable-diffusion.cpp is an open-source project that allows you to run Stable Diffusion models using C++ and Vulkan for faster execution on supported GPUs. The project is hosted on GitHub, and you can find the repository here.

License and Restrictions for v1-5-pruned-emaonly-fp16.safetensors

The v1-5-pruned-emaonly-fp16.safetensors file is available under the CreativeML Open RAIL-M license, which is a permissive license designed to allow use in research and commercial applications. However, you must ensure that your usage complies with all applicable laws and ethical guidelines, especially when generating or distributing images. Be sure to review the full license before use.

How to Compile stable-diffusion.cpp with Vulkan

Since ROCm 6.4 dropped support for the AMD Instinct Mi60, I’ve opted to compile stable-diffusion.cpp with Vulkan for GPU acceleration. Below are the steps to compile it:

1. Clone the Repository:

git clone https://github.com/leejet/stable-diffusion.cpp
cd stable-diffusion.cpp

2. Install Dependencies:

For Fedora (adjust for your distro):

sudo dnf install cmake vulkan vulkan-devel clang++ libvulkan

3. Build the Project:

From within the stable-diffusion.cpp directory, create the build directory and compile:

mkdir build
cd build
cmake ..
make

4. Set Vulkan as the Backend:

If Vulkan is correctly installed, it will be detected automatically. If not, make sure you have the Vulkan SDK installed and your GPU drivers support Vulkan.

5. Run the Program:

Once compiled, you can use the following command to generate an image with the v1-5-pruned-emaonly-fp16.safetensors model:

./stable-diffusion -i "A beautiful landscape" -m /path/to/v1-5-pruned-emaonly-fp16.safetensors

Adjust the prompt and model path as necessary.

What are ROCm, Vulkan, and OpenCL?

• ROCm (Radeon Open Compute) is a software stack that provides a set of tools and libraries for high-performance computing on AMD GPUs. ROCm typically provides better integration with deep learning frameworks and libraries.
• Vulkan is a low-level, cross-platform graphics API that provides efficient access to modern GPUs. It’s highly flexible and allows direct control of GPU resources, making it ideal for tasks like real-time graphics rendering or AI model inference, as in this case.
• OpenCL (Open Computing Language) is an older, open standard for parallel computing. It works on both CPUs and GPUs and is used for a wide range of tasks, including image processing and machine learning. Unlike Vulkan, OpenCL is more generalized but can be less efficient for certain tasks.

Where to Place Your Models

Model Type	Folder
Checkpoints (e.g. *.safetensors)	ComfyUI/models/checkpoints/
LoRA models	ComfyUI/models/loras/
VAEs	ComfyUI/models/vae/
ControlNet	ComfyUI/models/controlnet/

Just drop your files into the appropriate folder and rerun stable-diffusion.cpp.
