Free and open source GPU compiled by hands" typically refers to GPU-related software—such as drivers, compute libraries, or frameworks—that is available under an open-source license and manually compiled from source code by the user. This approach allows greater control, customization, and transparency compared to using precompiled binaries.

Examples include:

1. Mesa3D (open-source implementation of OpenGL/Vulkan)
2. ROCm (AMD’s open-source GPU computing platform)
3. LLVM with GPU backends
4. Custom-built CUDA-compatible components in open-source AI frameworks (e.g., PyTorch, TensorFlow)

Compiling these tools "by hand" usually involves configuring build scripts, resolving dependencies, and tuning performance manually. Enthusiasts, researchers, or developers often do this to optimize for specific hardware, test experimental features, or maintain full control over the toolchain.-

This is apparently what the front looks like.

Still more reliable than Wayland on nvidia.

also doubles as an electrical fire generator, very versatile

Typical spaghetti code

Mine almost looks that good

This looks more like the boards they used in the 60s and 70s in prototyping. I have done such a board myself in my youth. All 40xx and 74LSxx DIL chips and a plain dot board. And a sh-tload of patching wire where I had to remove the isolation paint before I could solder that stuff.

I don't think you could build a working GPU with that wirewrap technology, the frequncies needed are simply to high.

If it's open, looks don't matter. Also doesn't matter if the drivers are trash, or if it runs zero games. It's all fixable trash - that's the point.

(Also, that's not a GPU, but it's the thought that counts)

What am I looking at?

Haywire. You don't see that often anymore.

Judging by the craiglist watermark on the bottom right, it's probably just a meme listing.

Why does this look like when i first iterate a pcb and need to bodge the hell out of it to make it work.

You switched two wires.

Dedication to wire this up manually is amazing.

Me when I forget about FPGAs

Is there more info about this? I could only find Chinese forums like https://m-weibo-cn.translate.goog/status/OdaBMza1L?from=page_1005052963774131_profile&wvr=6&mod=weibotime&jumpfrom=weibocom

The chips (basic TTL logic, perhaps) are all DIP. This may predate the term "open source".

What's its name

Messy cabling. Pull them out.
