Description
This extension adds several new features building on the cooperative matrix types added in VK_KHR_cooperative_matrix. The goal is to add and accelerate features beyond just simple GEMM kernels, including adding support for type/use conversions, reductions, per-element operations, and tensor addressing, and also to improve usability and out-of-the-box performance by adding support for more flexible matrix sizes, and workgroup scope matrices with compiler-managed staging through shared memory.
The new functionality is defined by the
SPV_NV_tensor_addressing
and
SPV_NV_cooperative_matrix2
SPIR-V extensions and can be used with the
GLSL_NV_cooperative_matrix2
GLSL extension.
This extension includes support for enumerating the matrix types and dimensions that are supported by the implementation, and which specific features are supported.
