Set Data Properties VI

Owning Palette: LVCUDA SDK

Requires: GPU Analysis Toolkit

Assigns the device data and properties in the device data class. Wire data to the CUDA U8 Device Ptr in input to determine the polymorphic instance to use. You can wire a CUDA device pointer, CUDA context, CUFFT handle, or CUBLAS handle to this VI.

For more information about how to use the LVCUDA SDK and LVGPU SDK VIs, refer to the KnowledgeBase article Customizing GPU Computing Using the GPU Analysis Toolkit at ni.com.

Set Data Properties (Device Ptr:U8)

The connector pane displays the default data types for the Device Ptr instance of this polymorphic function.

	CUDA Context specifies the device context class to create the device pointer.
	CUDA U8 Device Ptr in specifies a device pointer class. This input can contain the following data types: 8-bit unsigned integers 16-bit unsigned integers 32-bit unsigned integers 8-bit signed integers 16-bit signed integers 32-bit signed integers Single-precision, floating-point numbers Double-precision, floating-point numbers Complex single-precision, floating-point numbers Complex double-precision, floating-point
	U8 * specifies the device pointer.
	dim specifies the number of elements the device pointer allocates.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	CUDA U8 Device Ptr out returns the device pointer class. This output returns the same data type that you wire to CUDA U8 Device Ptr in.
	error out contains error information. This output provides standard error out functionality.

Set Data Properties (Context)

	CUDA Context in specifies a device context class.
	CUcontext specifies the CUDA context.
	Is Primary? specify TRUE if the Initialize Device VI creates the context passed to CUcontext.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	CUDA Context out returns the device context class.
	error out contains error information. This output provides standard error out functionality.

Set Data Properties (CUFFT Handle)

	CUFFT Handle in specifies a CUFFT handle class.
	cufftHandle specifies the CUFFT handle.
	CUDA Context specifies the device context class in which the CUFFT handle was created.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	CUFFT Handle out returns the CUFFT handle class.
	error out contains error information. This output provides standard error out functionality.

Set Data Properties (CUBLAS Handle)

	CUBLAS Handle in specifies a CUBLAS handle class.
	cublasHandle_t specifies the CUBLAS handle.
	CUDA Context specifies the device context class in which the CUFFT handle was created.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	CUBLAS Handle out returns a CUBLAS handle class.
	error out contains error information. This output provides standard error out functionality.

Set Data Properties Details

The data value reference returned in the CUDA U8 Device Ptr out, CUDA Context out, CUFFT Handle out, or CUBLAS Handle out output stores the device data. Wire this output to a Data Value Reference Read Element border node on an In Place Element structure, which locks the data value reference while you operate on the code inside the In Place Element structure. To unlock the device data, wire it to the Data Value Reference Write Element node. You can make the device data available to other processes by wiring the output of the Data Value Reference Write Element node to the Prepare Data for Unlock VI.
