It's the same as CUDA from Nvidia, but standardized and not limited to  
GPU.
You write a task (using the C subset provided by OpenCL), and then,  
you ask OpenCL to execute it on the what it found (CPU, GPU, DSP,  
other processing unit).
There is a sample code on wikipedia:

And you can also have a look at the official OpenCL web site (http://www.khronos.org/opencl/ 
). There is a slideshow that present it.
