backgammon bots and GPUs?

When you fill up the matrix with vectors you loose the ability to prune the bad moves, so it is a tradeoff.

The overhead of the transfer to the GPU looks too much for the small matrixes we have :(

SSE is a lot easier to use, it is widespread (sorry G4/G5 folks), the overhead is small (not so small with Java) and no problems with driver support. I'm curios how much AVX will gain. From my experiences with Java and 32/64-Bit / several operating systems / CPU the speedup were *very* different (from close to nothing with AMD+32Bit OS up to 70% i7 with 64-Bit OS).

ciao Frank
