1) petsc4py will provide a method Vec.getCUDAAddress() that will return a plain Python integer (and a corresponding restoreCUDAAddress()). Any other name to suggest? Using "CUDAArray" would be a bit misleading in Python land.
Perhaps "getCUDAHandle()" is better? Please help me to decide, I'm really bad at naming things.
I like handle. That is the traditional name.
Thanks! Take a look at branch dalcinl/cuda-handle

Great! Thanks, Matt
PS: Ashwin, you could use contextmanager https://docs.python.org/2/library/contextlib.html#contextlib.contextmanager to handle the get/restore using Python's with statement, eg.
with gpuarray(vec) as array: launch_cuda_kernel(array)
