Zeta OpenCL Chess - Developer Release 09521 - YBWC fails

[smatovic]

fyi: i published the Code of my GPU-YBWC approach on github:

https://github.com/smatovic/Zeta/tree/zeta_nvidia_09521

the implementation doesnt scale with more than one SIMD Unit activated:

At least the algorithm produces correct results....

Works on windows 7 x64??

I have a AMD GPU I'm downloading the AMD APP SDK 2.6 x64 for windows and I'm curious to test it

Thanks

Ive tested only Linux64.

I can make an amd branch for you, but i can not test....

I have downloaded the amd version that you have on github but it had two files COPYING and README files

That sounds good, I will apreciate that

Thanks
