I am using Nsignt in Visual Studio 2015 for analyzing performance of a NVIDIA Optix application. The UI of the application is written in Python.
As you can see in the Timeline, there are completely empty columns between 2.6152 to 2.6163. I don’t understand what CUDA is doing right there, nor why it is empty. The last Driver API and Function Calls before the empty columns is cuEventElapsedTime
I have only One GPU, the ray-traced scene is simple and only device to device copy should occur for outputs.
Please help, thanks
