My 'can access' simply means that I'm able to access the values in the variable in python by typing x1 or x2. My understanding is that if the variables are stored on different GPUs, then I should be able to type x1 and get its values when ctx1 is active and similarly, I can type x2 and get the x2 values when ctx2 is active, not when ctx1 is active.
