Functions

__host__ ​cudaError_t cudaD3D11GetDirect3DDevice ( ID3D11Device** ppD3D11Device )

Gets the Direct3D device against which the current CUDA context was created.

Parameters

ppD3D11Device

- Returns the Direct3D device for this thread

Returns

cudaSuccess, cudaErrorUnknown

Deprecated

This function is deprecated as of CUDA 5.0.

Description

This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA device with a D3D11 device in order to achieve maximum interoperability performance.

Note:

Note that this function may also return error codes from previous, asynchronous launches.

__host__ ​cudaError_t cudaD3D11SetDirect3DDevice ( ID3D11Device* pD3D11Device, int  device = -1 )

Sets the Direct3D 11 device to use for interoperability with a CUDA device.

Parameters

pD3D11Device

- Direct3D device to use for interoperability

device

- The CUDA device to use. This device must be among the devices returned when querying cudaD3D11DeviceListAll from cudaD3D11GetDevices, may be set to -1 to automatically select an appropriate CUDA device.

Returns

cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidValue, cudaErrorSetOnActiveProcess

Deprecated

This function is deprecated as of CUDA 5.0.

Description

This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA device with a D3D11 device in order to achieve maximum interoperability performance.

This function will immediately initialize the primary context on device if needed.

Note:

Note that this function may also return error codes from previous, asynchronous launches.
