D3D12 LinAlg Matrix Preview (devblogs.microsoft.com)

The D3D12 Linear Algebra API Preview has been announced, allowing developers to harness hardware acceleration for matrix operations in real-time graphics and machine learning applications. This comprehensive feature set integrates previously separate matrix operation APIs—WaveMMA and Cooperative Vectors—into a unified framework. It enables advanced techniques like neural rendering directly from shader threads, effectively bridging the gap between graphics programming and machine learning, which is increasingly crucial across industries. This update is particularly significant as it responds to the growing demand for efficient GPU utilization in machine learning and graphics, facilitating the seamless integration of neural networks into rendering processes. The API introduces three modes of operation—MatrixScope::Thread, MatrixScope::Wave, and the new MatrixScope::ThreadGroup—tailored for different matrix size needs and performance optimizations. By automating matrix tiling decisions, the new ThreadGroup mode simplifies implementation for larger models typical in cutting-edge AI workloads, making it easier for developers to leverage specialized hardware capabilities without manual adjustment. The release is part of the Shader Model 6.10 offering, promising continued evolution based on user feedback.
