Rust LLM inference engine faces CUDA GPU integration challenges

By PulseAugur Editorial · [1 sources] ·

The author details their experience integrating a Rust LLM inference engine, mini-vllm-rs, with NVIDIA GPUs using CUDA. Initially expecting a simple recompilation, they encountered several issues including F16 activation failures and a CPU optimization that incorrectly affected GPU performance. After resolving these problems, they were able to run models like Qwen2.5 0.5B and Llama-3.1 8B on Kaggle's free T4 GPUs, though F16 activations still produced corrupted text on CUDA for larger models, leading to a fallback to F32.

    When "Just Enable the CUDA Feature" Met Two Free GPUs

    <p>If a Rust LLM inference engine already runs on CPU and Apple Metal, and its tensor framework supports CUDA, how hard could it be to run it on NVIDIA GPUs?</p> <p>I expected a simple recompile. Instead, moving <a href="https://github.com/lun0522/mini-vllm-rs" rel="noopener nore…
