Tutorial Node: Attributes With CUDA Array Pointers In Cpu Memory
This is a tutorial node. It illustrates the alternative method of extracting pointers to GPU array data in which the pointer returned is a CPU pointer and can be dereferenced on the CPU side. Without the cudaPointers value set that pointer would be a GPU pointer to an array of GPU pointers and could only be dereferenced on the device.
Installation
To use this node enable omni.graph.tutorials in the Extension Manager.
