If you need any additional info please don't hesitate to > ask. 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. saludos, alain
