alt Hacker NewsCUDA has many problems, but I would say less problems than ROCm, etc; even before considering the ecosystem and that more people (or open source projects) have already solved CUDA's problems for you.
Ironically, there was an open source project that was making great progress on CUDA compatibility on AMD hardware. AMD hired the lead developer, and then he shut down the project.
ZLUDA is still alive. AMD sponsored it and the project was briefly halted during a dispute with them, but it’s been making steady progress.
It doesn’t really make sense for AMD themselves or most use cases, though; any compatibility shim just adds problems on top of problems, and for AMD, entrenching a competitors technology even more never really seemed like a great idea.
