Is computer chess "solved"?
even if, then there is still the game of Go ;-)

Re: Possible Board Presentation and Move Generation for GPUs

I'd strongly recommend you take a look a look at my method inspired by Kogge-Stone parallel prefix networks,
Great, i think i got it...

i could use 8 Threads/Processes in parallel, for each direction one, just have to care for the non-sliding pieces...thanks.

Zeta Dva v 0.1.5.3

weak winboard engine without book support:

changes:
- en passant bugfixed
- incremental eval and hashing -> speedup
- added windows 64 bit exe, not tested

PS: thanks again to Jim for Time Control

Re: Possible Board Presentation and Move Generation for GPUs

No idea with GPUs. Do they have 64-bit shifts with 128-bit SIMD vectors? If yes, I guess Kogge-Stone is the way to go on these architectures.
Yes, they have, i guess i have to get closer into Kogge-Stone, thanks Steffan and Gerd.

Re: Possible Board Presentation and Move Generation for GPUs

Perhaps some more explicitly parallel algorithms could work, say allocating 8 threads for each piece, one for each possible direction, and generating all moves in parallel with a mailbox approach, or using rotated bitmaps and updating them in parallel. Yes, this is some kind of parallel move genera...

Re: Possible Board Presentation and Move Generation for GPUs

On the other hand, you then have a somewhat large amount of data that needs to be accessed efficiently by the different threads. I suspect that is not ideal either. Right, i have to use slow global memory with the magic bitboard approach. Perhaps the most efficient algorithm is simply to ask 64x64 ...
