Mirek,

I do not know whether you are asking for something sophisticated but I am attaching a very basic example of OpenCL in U++. It is the traditional �Hello World� example. The OpenCL code is in the file �example1_kernels.cl�.

In my case I downloaded the NVIDIA OpenCL drivers and other OpenCL files from the Khronos Group web page. I included the appropriate instructions in the Package Organizer.

My knowledge of OpenCL is limited but I am condemned to use it in the near future, due to the fact that for intensive math calculations is a fundamental tool.

Best wishes,

Javier

Roger that.

I am happy to hear that you are interested in OpenCL.

By the way, what about NTL with OpenCL? Can they work together?

Best wishes,
Javier

Do not know yet.

What I know (because I have been studying it currently) is that NTL would not work with SSE2. The problem is that SSE2 has requirements for memory alignement that basic U++ memory allocatator is unable to satisfy.

I am however thinking about fixing this issue.... Well, maybe impossible for Array containers, but should be possible for Vector.
