Functions

CUresult cuD3D11CtxCreate ( CUcontext* pCtx, CUdevice* pCudaDevice, unsigned int  Flags, ID3D11Device* pD3DDevice )

Create a CUDA context for interoperability with Direct3D 11.

Parameters

pCtx

- Returned newly created CUDA context

pCudaDevice

- Returned pointer to the device on which the context was created

Flags

- Context creation flags (see cuCtxCreate() for details)

pD3DDevice

- Direct3D device to create interoperability context with

Returns

CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN

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 context 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.

CUresult cuD3D11CtxCreateOnDevice ( CUcontext* pCtx, unsigned int  flags, ID3D11Device* pD3DDevice, CUdevice cudaDevice )

Create a CUDA context for interoperability with Direct3D 11.

Parameters

pCtx

- Returned newly created CUDA context

flags

- Context creation flags (see cuCtxCreate() for details)

pD3DDevice

cudaDevice

- The CUDA device on which to create the context. This device must be among the devices returned when querying CU_D3D11_DEVICES_ALL from cuD3D11GetDevices.

Returns

CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN
