Sets the current, active device context.

If you call the Pop Current Context VI after calling this VI, the previous, active context becomes the current context.

Note  You must call the Push Current Context VI from another VI that has subroutine priority set from the Execution page of VI Properties dialog box.


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

Push Current Context Details

This VI is equivalent to the Set Current Context VI when the CUDA Context in input references a primary context created by the Initialize Device VI.

Use the LVCUDA Driver API VIs with the LVCUDA SDK VIs to build wrappers for custom GPU VIs.

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.
