Phobos - Tiny scale-free kernel language for NVIDIA GPUs

Show HN: Phobos – A tiny scale-free kernel language with tile-DAG support

Phobos is a lightweight, scale-free kernel language inspired by Triton, designed to compile directly to PTX for execution on NVIDIA GPUs. Built with Rust and leveraging MLIR, it features first-class tensor types and native support for distributed tile-DAG designs. While developed as a personal research project to explore low-level GPU concepts, Phobos achieves impressive performance, reaching 76% of cuBLAS SGEMM GFLOP/s on an RTX 2080 SUPER. It offers developers a streamlined path to write optimized AI kernels without the complexity of traditional CUDA development.
