Hi Sylvain,

I gave it a try this morning but didn't work on my acer laptop with
NVIDIA GeForce GT 330M
Driver version: 319.32 on 64 bit Xubuntu 13.10

It's not quite clear to me how to get opencl installed... I installed
a package called nvidia-opencl-dev and opencl-headers but didn't see
anything else in the package manager.

I have not installed glfw3 as it appears to be an optional component,
is that true?
