Tutorial Python Node: CPU/GPU Extended Attributes
This is a tutorial node. It exercises functionality for accessing data in extended attributes that are on the GPU as well as those whose CPU/GPU location is decided at runtime. The compute adds the two inputs ‘gpuData’ and ‘cpuData’ together, placing the result in cpuGpuSum, whose memory location is determined by the ‘gpu’ flag. This node is identical to OgnTutorialCpuGpuExtended.ogn, except is is implemented in Python.
Installation
To use this Node, you must enable omni.graph.tutorials in the Extension Manager.

Sum (cpuGpuSum) |
|
This is the attribute with the selected data. If the ‘gpu’ attribute is set to true then this attribute’s contents will be entirely on the GPU, otherwise it will be on the CPU. |
