Key Points

  • The post discusses Nvidia GreenBoost, a kernel module claimed to boost LLM performance by extending CUDA memory with DDR4 RAM.
  • The author questions its usefulness for optimized setups and notes that benchmarking with ollama is nice but prefers using llama.cpp or vllm for evaluation.
  • The discussion links to a Phoronix article and a Reddit thread, and invites others to share their experiences.
  • Overall, the content is exploratory and seeks community opinions rather than presenting a confirmed breakthrough.

Reading phoronix I have stumbled over a post mentioning https://gitlab.com/IsolatedOctopi/nvidia_greenboost , a kernel module to boost LLM performance by extending the CUDA memory by DDR4 RAM.

The idea looks neat, but several details made me doubt this is going to help for optimized setups. Measuring performance improvements using ollama is nice but I would rater use llama.cpp or vllm anyways.

What do you think about it?
