Any development on this?
@svanschalkwyk @dakami I've successfully used CUDA 8.0 on my machine (with Titan GPU with Pascal). Did you use the maven update? (It's on the Wiki page right now on this GitHub).
It is only seeing one of the two CUDA devices. I have export CUDA_VISIBLE_DEVICES=1,2
I downloaded the pre-built binaries and they also show only one device. "1 CUDA device found, CUDA version 7.0"

[SOLVED] CUDA_VISIBLE_DEVICES have to follow the numbering that nvidia-smi shows, i.e. 0 for GPU 0, 1 for GPU 1. Suggestions (somewhere else) that the GPU array is 1-based are incorrect.
./getdevlibs.sh doesn't find any 8.0 libraries, and the icc dependency makes it impossible to rebuild locally. Might be nice to have a GPU only build path, but would definitely be nice if I could build against CUDA 8 / these Titans.
