OpenCL

[Gabriel Jacobo]

Hey everyone, I was wondering if someone could give me more information about the implementation of the OpenCL proposal: http://wiki.cython.org/enhancements/opencl

I've found some discussion about it from early 2012, but besides that it doesn't seem it got implemented at all, is that correct?

I was playing with OpenCL kernels + cython wrapped C++ code and translated it into plain Python + pyopencl.
No performance loss was observed. pyopencl is really great (even if bound with boost)

I know it does not answer your question but it may explain the lack of interest on the Cython/OpenCL part.

I think the closest you'll come in spirit is the CUDA support in Numba.

Thanks, I was looking at something more along the lines of the prange/openmp implementation, but I guess a more "manual" approach won't be that difficult to implement.
