Efficient parallism
Efficient parallism in Chess is hard. I try different approaches. The multi-window one gives the best results so far.

Beated by the GPU in Chess
Okay, I am not that strong player but I got beaten by my chess chess eninge written in CUDA running on a NVIDIA GeForce 8800 GTX.

Tiny chess engine running
After performing some tests I have a chess engine running as one block on a multiprocessor, using alpha/beta using killer moves as well

Parallel move generation
One of the advantages of using GPU's multiprocessors. Instead of generation all pseudo legal moves for a given chess position in sequence, I use 64 threads to generate all legal moves parallel!
Alpha beta
Recursion is not possible on the GPU, because the processor on the GeForce 8800 has not stack. Therefore I needed to implement recursion with a state machine and a array which simulates the stackpointer.

TCSP
I used Tom Kerrigan's Simple Chess program as a starting point to test if chess would be possible on a GPU.

Challenge
I started this challenge in january 2007. The challenge is to implement a chess engine purely running on graphical adapters. The idea came after the launch of NVIDIA's CUDA, a SDK to program GPU's.
