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_NV_cooperative_matrix SPIR-V extension and can be used with the GL_NV_cooperative_matrix GLSL extension.

This extension includes support for enumerating the matrix types and dimensions that are supported by the implementation.

Issues

  1. What matrix properties will be supported in practice?

RESOLVED: In NVIDIA’s initial implementation, we will support:

  • AType = BType = fp16 CType = DType = fp16 MxNxK = 16x8x16 scope = Subgroup

  • AType = BType = fp16 CType = DType = fp16 MxNxK = 16x8x8 scope = Subgroup

  • AType = BType = fp16 CType = DType = fp32 MxNxK = 16x8x16 scope = Subgroup

  • AType = BType = fp16 CType = DType = fp32 MxNxK = 16x8x8 scope = Subgroup

vkGetPhysicalDeviceCooperativeMatrixPropertiesNV - Returns properties describing what cooperative matrix types are supported

Description

If pProperties is NULL, then the number of cooperative matrix properties available is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the application to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If pPropertyCount is less than the number of cooperative matrix properties available, at most pPropertyCount structures will be written, and INCOMPLETE will be returned instead of SUCCESS, to indicate that not all the available cooperative matrix properties were returned.

Valid Usage (Implicit)

  • pPropertyCount must be a valid pointer to a uint32_t value

  • If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount CooperativeMatrixPropertiesNV structures

VkPhysicalDeviceCooperativeMatrixFeaturesNV - Structure describing cooperative matrix features that can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceCooperativeMatrixFeaturesNV structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceCooperativeMatrixFeaturesNV, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.

VkCooperativeMatrixPropertiesNV - Structure specifying cooperative matrix properties

Description

If some types are preferred over other types (e.g. for performance), they should appear earlier in the list enumerated by getPhysicalDeviceCooperativeMatrixPropertiesNV.

At least one entry in the list must have power of two values for all of MSize, KSize, and NSize.
