VkPhysicalDeviceCooperativeVectorPropertiesNV(3)

Name

VkPhysicalDeviceCooperativeVectorPropertiesNV - Structure describing cooperative vector properties supported by an implementation

C Specification

The VkPhysicalDeviceCooperativeVectorPropertiesNV structure is defined as:

// Provided by VK_NV_cooperative_vector
typedef struct VkPhysicalDeviceCooperativeVectorPropertiesNV {
    VkStructureType       sType;
    void*                 pNext;
    VkShaderStageFlags    cooperativeVectorSupportedStages;
    VkBool32              cooperativeVectorTrainingFloat16Accumulation;
    VkBool32              cooperativeVectorTrainingFloat32Accumulation;
    uint32_t              maxCooperativeVectorComponents;
} VkPhysicalDeviceCooperativeVectorPropertiesNV;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
cooperativeVectorSupportedStages is a bitfield of VkShaderStageFlagBits describing the shader stages that cooperative vector instructions are supported in. cooperativeVectorSupportedStages will have the VK_SHADER_STAGE_COMPUTE_BIT bit set if any of the physical device’s queues support VK_QUEUE_COMPUTE_BIT.
cooperativeVectorTrainingFloat16Accumulation is VK_TRUE if the implementation supports cooperative vector training functions accumulating 16-bit floating-point results.
cooperativeVectorTrainingFloat32Accumulation is VK_TRUE if the implementation supports cooperative vector training functions accumulating 32-bit floating-point results.
maxCooperativeVectorComponents indicates the maximum number of components that can be in a cooperative vector.

Description

If the VkPhysicalDeviceCooperativeVectorPropertiesNV structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

VUID-VkPhysicalDeviceCooperativeVectorPropertiesNV-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COOPERATIVE_VECTOR_PROPERTIES_NV
