The Vulkan 1.1.101 spec release includes the VK_NV_cooperative_matrix extension. This extension adds support for using cooperative matrix types in SPIR-V. Cooperative matrix types are medium-sized matrices that are primarily supported in compute shaders, where the storage for the matrix is spread across all invocations in some scope (usually a subgroup) and those invocations cooperate to efficiently perform matrix multiplies. These operations are accelerated by NVIDIA Tensor Cores on Turing GPUs.

The task list for the VK_NV_cooperative_matrix extension release is:

As each component is made public, the task will be checked off. When all tasks have been completed this issue will be closed and the extension will be fully released.

Driver versions 419.09 (Windows) and 418.31.03 (Linux) implement this extension and can be found here: https://developer.nvidia.com/vulkan-driver.

@pdaniell-nv can't see this interesting extension (VK_NV_cooperative_matrix) exposed on Titan V (Volta) on 419.09..
https://vulkan.gpuinfo.org/compare.php?compare=compare&id%5B5264%5D=on&id%5B4960%5D=on
is that expected? it's because Volta Tensor cores aren't "rich enough" to support it?
thanks..

Right, this is only currently supported on Turing.
