Add OpenCL support with Aparapi for Geoprocessing in gvSIG desktop

 * Product: gvSIG Desktop
 * Possible mentor: Cèsar Ordiñana
 * Possible student: Paula Navarro

Aparapi is a library which allows Java developers to take advantage of the compute power of GPU and APU devices by executing data parallel code fragments on the GPU rather than being confined to the local CPU. It does this by converting Java bytecode to OpenCL at runtime and executing on the GPU, if for any reason Aparapi can't execute on the GPU it will execute in a Java thread pool.

Large amounts of geographic data-processing might be involved in the execution of a geoprocess. And many geoprocessing algorithms are suitable to be converted to parallel code, allowing for much better execution performance and capacity.

The objective would be to integrate the Aparapi library in gvSIG, so it might be used in the development of new parallel geoprocessing algorithms which take advantage of current GPUs. Also some geoprocesses would have to be developed or converted to use the Aparapi library to check the benefits and the proper operation of the idea.
