Note that the performance for many tasks will be far inferior to an actual GPU, but you can learn the programming model with an emulator.
Problem
I do not have a GPU card installed in my system. I would like to know if there is any way I can code in CUDA and access CUDA libraries on my GPU-less laptop?
