Function Documentation

ORT_API_STATUS	(	OrtSessionOptionsAppendExecutionProvider_DML	,
		_In_ OrtSessionOptions *	options,
		int	device_id
	)

[[deprecated]] This export is deprecated. The OrtSessionOptionsAppendExecutionProvider_DML export on the OrtDmlApi should be used instead.

Creates a DirectML Execution Provider which executes on the hardware adapter with the given device_id, also known as the adapter index. The device ID corresponds to the enumeration order of hardware adapters as given by IDXGIFactory::EnumAdapters. A device_id of 0 always corresponds to the default adapter, which is typically the primary display GPU installed on the system. A negative device_id is invalid.

ORT_API_STATUS	(	OrtSessionOptionsAppendExecutionProviderEx_DML	,
		_In_ OrtSessionOptions *	options,
		_In_ IDMLDevice *	dml_device,
		_In_ ID3D12CommandQueue *	cmd_queue
	)

[[deprecated]] This export is deprecated. The OrtSessionOptionsAppendExecutionProvider_DML1 export on the OrtDmlApi should be used instead.

Creates a DirectML Execution Provider using the given DirectML device, and which executes work on the supplied D3D12 command queue. The DirectML device and D3D12 command queue must have the same parent ID3D12Device, or an error will be returned. The D3D12 command queue must be of type DIRECT or COMPUTE (see D3D12_COMMAND_LIST_TYPE). If this function succeeds, the inference session maintains a strong reference on both the dml_device and the command_queue objects. See also: DMLCreateDevice See also: ID3D12Device::CreateCommandQueue
