Can anybody explain why CUDA and Rocm are necessary and why OpenCL isn't the solution? (programming.dev)

I've read multiple times that CUDA dominates, mostly because NVIDIA dominates. Rocm is the AMD equivalent, but OpenCL also exists. From my understanding, these are technologies used to program graphics cards - always thought that shaders were used for that.

There is a huge gap in my knowledge and understanding about this, so I'd appreciate somebody laying this out for me. I could ask an LLM and be misguided, but I'd rather not 🤣

I can't say as to why things are how they are. It's likely just the usual open source lagging behind; These technologies are fairly new and the corporate stronghold around them is strong.

Shaders are programs that run on graphics cards to act as shortcuts for common graphic scenarios, they are not programs that dictate how graphic cards function. That could clear up some confusion.
