Methods

cuArray3DCreate_v2(ref CUarray, ref CUDAArray3DDescriptor)

Creates a CUDA array according to the CUDAArray3DDescriptor structure pAllocateArray and returns a handle to the new CUDA array in pHandle.

Declaration

public static CUResult cuArray3DCreate_v2(ref CUarray pHandle, ref CUDAArray3DDescriptor pAllocateArray)

Parameters

Type	Name	Description
CUarray	pHandle	Returned array
CUDAArray3DDescriptor	pAllocateArray	3D array descriptor

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorOutOfMemory, ErrorUnknown. Note that this function may also return error codes from previous, asynchronous launches.

cuArray3DGetDescriptor_v2(ref CUDAArray3DDescriptor, CUarray)

Returns in pArrayDescriptor a descriptor containing information on the format and dimensions of the CUDA array hArray. It is useful for subroutines that have been passed a CUDA array, but need to know the CUDA array parameters for validation or other purposes.

This function may be called on 1D and 2D arrays, in which case the Height and/or Depth members of the descriptor struct will be set to 0.

Declaration

public static CUResult cuArray3DGetDescriptor_v2(ref CUDAArray3DDescriptor pArrayDescriptor, CUarray hArray)

Parameters

Type	Name	Description
CUDAArray3DDescriptor	pArrayDescriptor	Returned 3D array descriptor
CUarray	hArray	3D array to get descriptor of

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorInvalidHandle. Note that this function may also return error codes from previous, asynchronous launches.

cuArrayCreate_v2(ref CUarray, ref CUDAArrayDescriptor)

Creates a CUDA array according to the CUDAArrayDescriptor structure pAllocateArray and returns a handle to the new CUDA array in pHandle.

Declaration

public static CUResult cuArrayCreate_v2(ref CUarray pHandle, ref CUDAArrayDescriptor pAllocateArray)

Parameters

Type	Name	Description
CUarray	pHandle	Returned array
CUDAArrayDescriptor	pAllocateArray	Array descriptor

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorOutOfMemory, ErrorUnknown. Note that this function may also return error codes from previous, asynchronous launches.

cuArrayDestroy(CUarray)

Destroys the CUDA array hArray.

Declaration

public static CUResult cuArrayDestroy(CUarray hArray)

Parameters

Type	Name	Description
CUarray	hArray	Array to destroy

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidHandle, ErrorArrayIsMapped. Note that this function may also return error codes from previous, asynchronous launches.

cuArrayGetDescriptor_v2(ref CUDAArrayDescriptor, CUarray)

Returns in pArrayDescriptor a descriptor containing information on the format and dimensions of the CUDA array hArray. It is useful for subroutines that have been passed a CUDA array, but need to know the CUDA array parameters for validation or other purposes.

Declaration

public static CUResult cuArrayGetDescriptor_v2(ref CUDAArrayDescriptor pArrayDescriptor, CUarray hArray)

Parameters

Type	Name	Description
CUDAArrayDescriptor	pArrayDescriptor	Returned array descriptor
CUarray	hArray	Array to get descriptor of

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorInvalidHandle. Note that this function may also return error codes from previous, asynchronous launches.

cuMipmappedArrayCreate(ref CUmipmappedArray, ref CUDAArray3DDescriptor, UInt32)

Creates a CUDA mipmapped array according to the ::CUDA_ARRAY3D_DESCRIPTOR structure pMipmappedArrayDesc and returns a handle to the new CUDA mipmapped array in pHandle. numMipmapLevels specifies the number of mipmap levels to be allocated. This value is clamped to the range [1, 1 + floor(log2(max(width, height, depth)))].

Declaration

public static CUResult cuMipmappedArrayCreate(ref CUmipmappedArray pHandle, ref CUDAArray3DDescriptor pMipmappedArrayDesc, uint numMipmapLevels)

Parameters

Type	Name	Description
CUmipmappedArray	pHandle	Returned mipmapped array
CUDAArray3DDescriptor	pMipmappedArrayDesc	mipmapped array descriptor
System.UInt32	numMipmapLevels	Number of mipmap levels

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorOutOfMemory, ErrorUnknown.

cuMipmappedArrayDestroy(CUmipmappedArray)

Destroys the CUDA mipmapped array hMipmappedArray.

Declaration

public static CUResult cuMipmappedArrayDestroy(CUmipmappedArray hMipmappedArray)

Parameters

Type	Name	Description
CUmipmappedArray	hMipmappedArray	Mipmapped array to destroy

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorInvalidHandle.

cuMipmappedArrayGetLevel(ref CUarray, CUmipmappedArray, UInt32)

Returns in pLevelArray a CUDA array that represents a single mipmap level of the CUDA mipmapped array hMipmappedArray.

Declaration

public static CUResult cuMipmappedArrayGetLevel(ref CUarray pLevelArray, CUmipmappedArray hMipmappedArray, uint level)

Parameters

Type	Name	Description
CUarray	pLevelArray	Returned mipmap level CUDA array
CUmipmappedArray	hMipmappedArray	CUDA mipmapped array
System.UInt32	level	Mipmap level

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue, ErrorInvalidHandle.
