cgos 9x9

Hello;
we would like to come back to Computer-Go,
starting with the small 9x9 board; is there any such Cgos running somewhere ?
Thanks to people currently running the 13x13.
Or maybe we should run a 9x9 server ourselves if nobody has this in
his/her agenda ?
Best regards,
Olivier

Photos from Computer Olympiad

Hello,

currently the Computer Olympiad 2015 and Computer Chess World
Championships are underway in Leiden (NL).

In Go the competitions on small boards are completed.
On 9x9 and 13x13 favorite Zen (Japan) took Gold.
Abakus (Paderborn, Germany) collected Silver on 9x9 and Bronze on 13x13.
13x13-Silver for Nomitan (Taiwan).
9x9-Bronze went to CGI (Taiwan).

NNGS go server


Is there a client to watch the games on NNGS go servers?

Thanks a lot

Using GPUs?

I wondered if any of the current go programs are using GPUs.

If yes, what is good to look for in a GPU? Links to essential reading on
this topic would be welcome. (*)

If not, is there some hardware breakthrough being waited for, or some
algorithmic one?

Darren

*: After many years of being happy with built-in graphics, I'm now
thinking to get a "gaming" PC, to show off some WebGL data
visualizations. Assuming the cost is in the same ballpark, I thought I'd
get one that would allow some scientific computing experiments too.

Re: Strange GNU Go ladder behavior

I got through the whole 640-game experiment without a crash!

(The cloud is a wonder, allowing me to play 640 games in under an hour.)

Many thanks to everyone for your help.

One game did run very long, thanks to GNU Go. See the time left signals in the SGF:

Re: Strange GNU Go ladder behavior

So what is the 64-bit problem? (Or did I misread?)

Strange GNU Go ladder behavior

This list may not be able to help, but I'm running out of clues on this one.

I'm trying to run an experiment playing Orego against GNU Go in many games. Some of the games don't end properly. As far as I can tell, here's what happens:

1) Orego plays out a losing ladder. (That needs to be fixed, but that's another problem.)
2) At some point in the ladder, GNU Go quietly dies without responding to the move request.

Has anyone else encountered this?

Re: Number of Go positions computed modulo 2^64; source code available

How much computation time do you expect to reveil the complete exact 
19x19 number? Or is more research necessary before I may ask this?
