The 2nd ACCA World Computer Rapid Chess Championship has finished and Rybka has won with 13.5/14, ahead of Sjeng, Hiarcs and TerraPi.

A huge thanks to Nick Carlin for handling everything on the Rybka side as well as to Lukas Cimiotti for again running Rybka remotely for us on his 4 GHz Skulltrail. There are various issues with playing automatically on ICC and the setup we used to play in the tournament was quite elaborate.

Jeroen has been busy with his upcoming opening book release (well, that and a few other things :)), so Nick used his own battle-hardened Playchess book, which performed very well.

Thanks also to Charles Roberson for again organizing the event.

Nick's reports during the course of the tournament can be found here.

My pleasure Vas, in retrospect it would have been good not to have used a book in the last round :)

Good luck with your Rybka 3 schedules.

Rybka won the exhibition(Simul),Sjeng Hiarcs8x won the Tournament.Hey thats an idea,can Rybka play more than one opponent at the same time?She would have to somehow store the position and score of each opponent,maybe for each game give it an assignment number and store it to hash,each number triggering where the last position  and score was left off or something along this idea.

I do not under stand,  "Rybka won simul.....Sjeng  Hiarcs8x won the tournament "  I thought rybka won the tournament, and didnt know anything about Simul. What tournament did Sjeng Hiarcs8x win ?
Thank you

In fact Bugchess was awarded 1st prize when they did the calculations that take the hardware into account.

Bug out,
Parent - - By lkaufman (*****) Date 2008-06-23 22:30
This is a humurous reference to a comment by (or about, I forget) GM Larry Evans when Bobby Fischer scored 11-0 in the U.S. Championship in or around 1964, with Larry Evans second at (I believe) 7.5. "Evans won the tournament, Fischer won the exhibition" or words to that effect.

Ah ha, got it, thank you

Larry you are reading my mind.That is where I got the comment exactly only you remember the dates.Larry is it possible to configure Rybka to play a simul in some future date.I know this is way out there but maybe possible in the near future.In other words one program(chess engine) playing multiple players or (programs)at once.Should be possible if not done already.
Parent - - By lkaufman (*****) Date 2008-06-25 01:25
I don't know any reason why an octal computer can't play eight games at once, one on each core, although I believe this won't work with the Fritz family GUIs now. In fact in my autotesting my octal is constantly doing exactly this.
Parent - - By FWCC (***) [us] Date 2008-06-25 01:52
Thanks Larry,I'm talking about a Chess Program playing more than one game at once,not the hardware.The program itself would be playing multiple games(simultaneous exhibition)but maybe what you stated has answered my question.Rybka herself would be playing against others AT THE SAME TIME.A match environment on a computer has a program playing against other engines one at a time.I'm talking about one program playing others at the same time(simultaneously). I see Rybka giving Simuls in the future.

Why would this be useful?

In the 1980s there was a dedicated computer that played simuls.  I think it was called the Mark V. I owned one but my memory is bad.   I think it simply did not ponder and spent a few seconds vs each opponent by remembering up to 12 board positions (not sure of the max).  Probably Steve can comment.

Jim you're right. It was Sci Sys Mark V, the first "micro computer chess champion". It's biggest rival at the time was Fidelity Sensory 9. Mark V was quite a breakthrough, and a bit of a technical mirracle. It used LCD board for displaying pieces, and was able to play up to 12 games simultaneously, and just the way you described it. Later, Saitek had a computer called Simultano, which was able to do the same thing. But there was no magic, if you set 3 secs/move, it would come up with moves for 12 games in about 36 seconds.
Parent - By FWCC (***) [us] Date 2008-06-27 04:02
Well I was correct as this idea(In the Mark V) has been tried,I'm over 20yrs late close to 30.Wow that's really remarkable that something like that was available over 20 years ago.Is this system still around today and if so in what form?A lot has changed in over 20 years and I'm sure if this system (program) was used it would do miracles by yesterday's standards.How strong was this computer probably at expert level at least?Was simul chess the program's main purpose?Lets bring this system back today and implement it to Rybka .

He Larry, that´s great! I don´t believe, that Aquarium can do this. Maybe you can start a Round Robin tournament at saturday, july 12th at 0 a clock. Rybka 3 against seven best opponents (CEGT 40/4 list single core; Fruit/Toga only once); tc=5 minutes, permanent brain on. So you have for each round 4 games à 10 minutes (10 minutes on your octal;) after 28 games each engine played against the other; after 56 games with both sides. After 560 games each engine has played 140 games. Time for this tournament will be ~ 2.3 days; so monday morning, july 14th you will know the rating of Rybka 3! :-) And you can check, if the other engines are grouped well.

PS: Opening book would be a difficult task. I wouldn´t like that Rybka 3 plays with new book. Best choice would be neutral book for all engines!
PS2: I´m sure, that Rybka 3 mp will be better than in this scenario!

Just two practical problems: I don't have any of the latest non-Rybka programs except for Deep Shredder 11, and I don't know which GUI will allow multiple instances to run at the same time on the same computer. Maybe someone out there can answer this question?
Parent - - By Vempele (Silver) [fi] Date 2008-06-25 16:04
Arena, Winboard, ChessGUI.
Parent - By lkaufman (*****) Date 2008-06-25 16:24
OK, thanks. That solves one of the two problems.

I know it is not clean - but it you create multiple accounts you can run the CB GUI's in each account using multiple logons.

I use this to run 3 instances of F11 on a quad without issue as long as you don't try and use the same database in different sessions concurrently.

Hi Larry,

I have used the Shredder GUI that comes with the UCI engine to do this. You can on an 8 core machine open it 8 times and play 8 single cpu matches at the same time with ponder off. Just be careful with hash settings etc and it works really well.

Best Wishes,
Harvey
Parent - By lkaufman (*****) Date 2008-06-25 14:22
Thanks. Unfortunately I made the mistake of buying Shredder 11 thru ChessBase so I didn't get the Shredder 11 GUI with it.
Parent - - By George Tsavdaris (****) Date 2008-06-26 10:08
And with what operating system?
Can Windows XP Home or PRO do that?

Also does Windows handle the CPU resources perfectly giving 100%(or anyway 99%) to each of 8 (engines+GUI)?
Or there are conflicts?

As for hash: If you have 4 GB RAM for example, then giving 256 MB to each of the 8 engine+GUI is fine but does Windows handle them fine or there is the possibility to have memory/RAM conflicts?
Parent - By Harvey Williamson (*****) Date 2008-06-26 10:18
I have done it using xp 64. Windows does seem to handle the cpu resources ok but you can set affinity for each instance of the gui and the engines loaded in it to 1 core. memory seems to not be an issue as long as you obey the usual rules of not allocating more than half your physical memory in total.

Congrats to all concerned!!!

well done Nick and Lukas and all involved,esp R3 as we now call it.
Parent - - By buffos (Silver) [gr] Date 2008-06-23 13:14
that .5 point was a marketing trick so we can all expect rybka 4.0 to make it 14/14 :) :) :) LOL
