HIP Ray Tracing
HIP RT is a ray tracing library for HIP, making it easy to write ray tracing applications in HIP.
The new Wave Matrix Multiply Accumulate (WMMA) instructions added in HLSL Shader Model 6.8 allow shader developers to accelerate Generalized Matrix Multiplication (GEMM) matrix operations of the form:
WMMA instructions task all threads in a wave to collaboratively perform a matrix-multiply operation with higher efficiency and throughput than previously achievable using SM 6.7 or earlier instructions.
GEMM operations have many uses in in signal-processing, physics simulations, machine learning, and computer vision.
Some examples include:
- Performing Fast-Fourier Transforms for signal processing, such as audio, radio, or radar applications
- Applying filters and post-processing to images
- Calculating deformation of objects and fluids, such as fluid/physics sim or molecular simulation
- Implementing deep learning operators – for example convolution, multi-layer-perceptron, neural radiance fields, and so on.
