I have a problem similar to: http://www.mathworks.com/matlabcentral/answers/137378-is-it-possible-to-run-matlab-with-parallel-computing-toolbox-on-amazon-gpu
I cannot get Matlab 2014a to see the K520 GPU on a g2.2xlarge linux instance. I am connected via ssh. I would appreciate any pointers to make matlab see the gpu on the machine...

Hi Deniz
I started a g2.2xlarge Linux instance and got R2014a to use the GPU, output is below. A possible difference is that I used a desktop version of Ubuntu 12.04 LTS.
