vk_cooperative_matrix_perf is a sample/benchmark demonstrating performance of using the VK_KHR_cooperative_matrix Vulkan extension, and the associated GL_KHR_cooperative_matrix GLSL extension.
The benchmark queries the supported matrix multiply sizes and precisions from the Vulkan implementation, and runs a couple different shaders at various tiles sizes and reports the performance in teraflops.
Running this application requires an NVIDIA Turing or newer GPU, and a recent driver that supports the VK_KHR_cooperative_matrix extension.
Modifying and rebuilding the shaders requires a glslangValidator.exe with GL_KHR_cooperative_matrix support. This is included Vulkan SDK version 1.3.261.0 and newer.
