Fearless Concurrency on the GPU: Safe GPU inference in Rust, competitive with vLLM/SGLang [R]
Researchers have developed cuTile Rust, a programming model that enables safe GPU inference by leveraging Rust's ownership and borrow checking to verify memory safety and data-race freedom. This approach is integrated into Grout, an inference engine built with cuTile Rust and Hugging Face, which achieves competitive performance with vLLM and SGLang for Qwen3 models. The safety features are nearly free in terms of performance, with safe GEMM operations showing minimal difference compared to hand-written low-level versions. AI
