The problem with this tests fails it is that i try to access normal
RAM from the GPU. Nvidia has a feature called "Zero Copy" in CUDA SDK
that made this possible (not all cards support it). In OpenCL do not
exists a way to ask for this support, i try a test and error method
but as we can see do not work. Maybe this approach works in GPU that
use host RAM memory.
