So I'm trying to get the K80 to work on Ubuntu 14.04 with Cuda instead of the OpenCL buy using https://github.com/Genoil/cpp-ethereum miner. I have followed the instructions for Ubuntu 14.04 and Cuda, and have followed the steps multiple times but now cannot get Cuda to work. here is a printout of 'Nvidia-smi'

I have read that the k80 has 2 sets of processor it has 24gb of ram available in 2 * 12gb you can only see the 1 of the processor above.
I downloaded cpp-ethereum followed the readme, I've never used CMake before but here is the output

What am I doing wrong?
Thanks
Also I'm confused by this step, "sudo apt-get https://github.com/Genoil/cpp-ethereum/blob/master/README.md -y install software-properties-common" apt-get then a git repository, what is trying to be accomplished here?
Best Answer
This was caused by somebody who tried to make copatibility with Fedora work. add
--std=c++11to the NVCC flags in CMakelists.txt in libethash-cuda folderSo, actually, you have to make some change to the cloned source.

Change from
To, by adding --std=c++11; :
