[fpc-pascal] OpenCL

[Lourival Mendes]

Thanks a lot for your answer Dmitry,

   Sorry for my dummy questions, but if I got the idea, the OpenCL
implementation, from NVidia for Windows, is available as .dll. and the
Pascal binding should be adapted to work with it. Also, there is some
troubles with the OpenCL and if I understood correctly, for while,
OpenCL is not available in a spread way to work in Windows, Mac and so
on, but probably CUDA is, but we don't have bindings for Pascal code
yet.

Hugs

Lourival
