public class VkCooperativeMatrixFlexibleDimensionsPropertiesNV extends org.lwjgl.system.Struct<VkCooperativeMatrixFlexibleDimensionsPropertiesNV> implements org.lwjgl.system.NativeResource
Structure specifying cooperative matrix properties.
Description

Rather than explicitly enumerating a list of supported sizes, VkCooperativeMatrixFlexibleDimensionsPropertiesNV advertises size granularities, where the matrix must be a multiple of the advertised size. The M and K granularities apply to rows and columns of matrices with Use of MatrixA, K, and N apply to rows and columns of matrices with Use of MatrixB, M, and N apply to rows and columns of matrices with Use of MatrixAccumulator.

For a given type combination, if multiple workgroup sizes are supported there may be multiple VkCooperativeMatrixFlexibleDimensionsPropertiesNV structures with different granularities.

All granularity values must be powers of two.

Note

Different A/B types may require different granularities but share the same accumulator type. In such a case, the supported granularity for a matrix with the accumulator type would be the smallest advertised granularity.

    • VkCooperativeMatrixFlexibleDimensionsPropertiesNV

      public VkCooperativeMatrixFlexibleDimensionsPropertiesNV(ByteBuffer container)
      Creates a VkCooperativeMatrixFlexibleDimensionsPropertiesNV instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.
