Utilising the gpu in a headless envrionment
Is there any way to have OpenCL run in a terminal (ubuntu 14.04) but still use the gpu to compute processes?
Depends on the GPU, for AMD yes, NVIDIA I'm not sure. See: http://devgurus.amd.com/thread/160838 for running AMD cards (simple version is just run with sudo and it will see the cards correctly, you can also edit some source files to remove that check). You can also just start an x-server with a fake screen IIRC, but I didn't have much luck with that.
