I have a GTX 980 with the second revision of the web driver for Yosemite. I can't seem to get CUDA to work at the moment. Any attempts to use the card with CUDA throw the following error:
Code:
all CUDA-capable devices are busy or unavailable
Despite this, the system can properly read all the CUDA properties of the card:
