Show HN: cuTile Rust: Safe, data-race-free GPU kernels in Rust

cuTile Rust ( cutile-rs ) is a tile-based system for writing memory-safe, data-race-free GPU kernels in idiomatic Rust. It extends Rust's ownership discipline across the GPU launch boundary: mutable tensors are partitioned into disjoint pieces before launch, immutable tensors are shared, and generated launchers preserve ownership while GPU work is in flight. The same model supports synchronous launches, asynchronous pipelines, and CUDA graph replay. The #[cutile::module] macro embeds a captured Rust AST for each kernel in the host binary; when a kernel is needed, cuTile Rust JIT-compiles that AST through CUDA Tile IR into a GPU cubin. Local opt-outs remain available when lower-level control is needed.
