add CUDA should work, just tried it locally. I would try it in a fresh project and post any errors here/on GitHub if you still run into them.
Still I have lots of code lines written
with CuArrays, and was wondering if sentences like…
I believe most all of the CuArrays interface should be exported under the CUDA namespace now. Porting should be a simple find-and-replace (e.g. just tested CuArrays.zeros → CUDA.zeros)
Hopefully somebody can explain the status of things now?
You can safely get rid of CuArrays, CUDAnative, CUDAdrv and CUDAapi now! See this announcement.
