User seeks FP8 LLM training config for SM120 GPU

By PulseAugur Editorial · [1 sources] ·

A user on Reddit is seeking advice on the optimal software, kernel, and configuration settings for training a large language model using FP8 precision on an SM120 GPU. They are encountering difficulties with fine-tuning, particularly with vLLM, and are finding that upscaling to BF16 is often necessary, which negates the benefits of FP8 training. AI

    So what’s the best software/kernel/config combo for SM120 FP8 training?
