Class NVCooperativeMatrix

org.lwjgl.vulkan.NVCooperativeMatrix

public class NVCooperativeMatrix
extends java.lang.Object

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.

nvkGetPhysicalDeviceCooperativeMatrixPropertiesNV

public static int nvkGetPhysicalDeviceCooperativeMatrixPropertiesNV(org.lwjgl.vulkan.VkPhysicalDevice physicalDevice,
                                                                    long pPropertyCount,
                                                                    long pProperties)

Unsafe version of: GetPhysicalDeviceCooperativeMatrixPropertiesNV

Parameters:

pPropertyCount - a pointer to an integer related to the number of cooperative matrix properties available or queried.

vkGetPhysicalDeviceCooperativeMatrixPropertiesNV

public static int vkGetPhysicalDeviceCooperativeMatrixPropertiesNV(org.lwjgl.vulkan.VkPhysicalDevice physicalDevice,
                                                                   java.nio.IntBuffer pPropertyCount,
                                                                   @Nullable
                                                                   VkCooperativeMatrixPropertiesNV.Buffer pProperties)

Returns properties describing what cooperative matrix types are supported.

C Specification

To enumerate the supported cooperative matrix types and operations, call:

 VkResult vkGetPhysicalDeviceCooperativeMatrixPropertiesNV(
     VkPhysicalDevice                            physicalDevice,
     uint32_t*                                   pPropertyCount,
     VkCooperativeMatrixPropertiesNV*            pProperties);

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)

• physicalDevice must be a valid VkPhysicalDevice handle
• 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 VkCooperativeMatrixPropertiesNV structures

Return Codes

On success, this command returns

• SUCCESS
• INCOMPLETE

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

Parameters:

physicalDevice - the physical device.

pPropertyCount - a pointer to an integer related to the number of cooperative matrix properties available or queried.

pProperties - either NULL or a pointer to an array of VkCooperativeMatrixPropertiesNV structures.
