Converting a data center GPU for desktop use A developer concluded a learning exercise on converting a data center GPU for desktop use, using an LLM to write a C++ fan-control program based on exact knowledge of the Linux AMD GPU driver. The project, which built on a prior fan-control script, yielded no further improvements and was intended solely as an educational exercise. Possibly the last on this topic. Working through the learning curve in using an LLM for development. As an example exercise, used the prior fan-control script as a base, and wrote a small C++ program, but with exact knowledge of the Linux AMD GPU driver. Frankly, ran out of ideas for improvement. This was meant as a learning exercise.
