Description
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.
Cooperative matrix types are defined by the
SPV_KHR_cooperative_matrix
SPIR-V extension and can be used with the
GLSL_KHR_cooperative_matrix
GLSL extension.
This extension includes support for enumerating the matrix types and dimensions that are supported by the implementation.
