RunMat: Open-Source MATLAB-Compatible Runtime for CPU and GPU Computing
By
nallana
Pure flour-power. Hearty enough to carry you through lunch.
Summary
RunMat is an open-source runtime for mathematical computing that allows users to write code in MATLAB syntax and automatically run it on both CPU and GPU without requiring license fees. The tool automatically fuses operations and intelligently routes computations between CPU and GPU, working across multiple platforms (Windows, macOS, Linux, WebAssembly) and hardware (NVIDIA, AMD, Apple Silicon, Intel GPUs). It requires no kernel code, rewrites, device flags, or vendor lock-in, and can be installed via CLI, embedded via NPM, or tried instantly in the browser without an account. Currently in pre-release (v0.3), it has passed thousands of tests but may have some rough edges.
