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

Synopsis

Documentation

getPhysicalDeviceCooperativeMatrixPropertiesNV Source #

Arguments

:: forall io. MonadIO io 
=> PhysicalDevice

physicalDevice is the physical device.

-> io (Result, "properties" ::: Vector CooperativeMatrixPropertiesNV) 

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 user 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. If pPropertyCount is smaller than the number of cooperative matrix properties available, 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
