Hi,
We have an application that must be able to work on image (texture) and it should run on CPU and GPU.
So, I would like to know if there is a way to efficiently transfer theses data to the kernel ?
1 - If I'm on the CPU, I transfer an array of bytes as any other information.
This way it work too for the GPU.
2 - If I'm on the GPU, I can use OpenGL interop ! But it will not work on the CPU !!!
So, is there a way to create one unique method to transfer and to work on theses data without looking if we are on the CPU or GPU?
If I'm on the GPU, will I got better performance if I use textures ? Or it is better to have my image in global memory ?
Thanks
