matrixmultiplyAI

matrixmultiplyAI is a software framework designed to optimize and accelerate matrix multiplication workloads by applying machine learning techniques to traditional high-performance computing approaches. It provides a modular stack that enables automatic selection of data layouts, tiling strategies, and kernel implementations to maximize throughput across diverse hardware.

The core architecture combines a front-end API for expressing matrix multiply operations with back-end code generation and a runtime that dispatches optimized kernels. Key components include a performance predictor and cost model trained on micro-benchmarks, a tuner that explores configurations, and a code generator capable of emitting device- and backend-specific kernels for CPUs, GPUs, and specialized accelerators. The framework aims to be backend-agnostic, supporting CUDA, ROCm, and native SIMD paths, along with batched and quantized variants to cover a range of machine learning and scientific computing workloads.

History and development have been driven by collaboration among academic researchers and industry practitioners. The project began in the early 2020s with the goal of making matrix multiplication more adaptable to evolving hardware without sacrificing numerical correctness. Public releases have focused on expanding backends, improving scheduling accuracy, and improving integration with popular machine learning libraries.

Usage and impact typically center on improving end-to-end throughput in deep learning pipelines, scientific simulations, and data analytics that rely on dense matrix multiplications. While the system often delivers performance gains, results can vary based on matrix size, data type, and hardware characteristics, and users may need initial benchmarking to identify the best configurations. The project adopts an open-source posture and maintains extensive documentation and examples to guide adoption.
