There is an ACCA event being run on the ICC this weekend:

http://www.taccl.org/ACCAWCRCC/2008ACCAWCRCC/2008WCRCC.html

Rybka, HIARCS, Thinker, Sjeng and DIEP are participating along with 30+ participants.

Round 1 just finished, Rybka had a comfortable win:

HIARCS is having a pretty straightforwards win over messchess with the black pieces also.

Second round, a nice Sicilian, Rybka's first move out of book with a +0.52 eval


Rybka(C) kibitzes: depth=14 time=5.94 node=3073750 speed=529974 score=+0.52 pv="Nxd5 Bf2 Bb7 O-O-O Bd6 Kb1 O-O Bc4 Ne5 Bg3 Qc7 Bxd5 Bxd5 Bxe5"


so possibly the opponent was underbooked

Also (surprisingly) it looks like HIARCS (with the white pieces) will lose against DIEP.

Looks like another book win against Alaric (=TerraPi) in round 3.  Rybka came out of book but then went back in, this has led to a considerable advantage on the clock also as can be seen in the attached image.

Round 4, Rybka and Yace both lead with 3/3 and meet eachother.  Without wishing to denigrate the engine, I think that Yace has done this well so far largely due to Armando's book, but now he has to play us who hopefully should be wise to his Playchess Hernandez-inspired h3 tricks :)  Note the comment from Luminarydebris (Zacks) :)

EDIT: Move 27 we are +7 score, USCF commentator John Timmel says:

TimmelJ(64): Rybka really knows how to advance pawns for an attack

EDIT 2. Again we came out and went back into book, fortunately outbooking Armando ... Yace resigned on move 31

Rybka will now take sole lead on 4/4, but a long way to go (14 rounds in total).

Great performance so far. When's the next games starting?

Parent - By Sesse (****) Date 2008-06-21 18:04 Edited 2008-06-21 18:19
Actually, HIARCS is now playing a game against Telepath, and Rybka just disconnected and came back in... What's happening?

Edit: Rybka vs. TheGiver seems to have started.

Edit 2: And Rybka seems to be heading for a win on knockout, after both players exiting their books very early.

Thanks Steinar, this next game started three minutes late (Rybka autologged out due to inactivity, something which isn't supposed to happen with the "keepAlive" winboard option as it should enter the "date" command every 30 minutes) but we're off to a win I think, I started followed the game late, but possibly our first move out of book had an eval > +0.5 for white.

Our current opponent is TheGiver = Crash Test Dummy/The Baron from Richard Pijl - operated by his 13 year old daughter I believe.  Here is the latest grid:

The Hamsters have played a reasonable opening. (1.d4 d5 game ..)

EDIT: 0-1.  HIARCS fought really well, but absolute and unadulterated class from Rybka, hats off to Vas and Larry.  Just look at move 54 from black! Well timed and brilliant, freestyle-like.  This game completes Phase One in our revenge on HIARCS for CCT10 :)

(Rybka-Sjeng coming up)
Parent - - By Sesse (****) Date 2008-06-21 19:27 Edited 2008-06-21 20:04
Both engines seemed to agree that Rybka was better off by half a pawn or so in a rather defensive game (nobody even crossed the middle line until the 20th move). The score is dropping, though, so nothing is decided yet.

Edit: +5 for Rybka now... Pretty much game, set and match. Nice!

Edit 2: You have to admire the ending... Suddenly Rybka had three queens, almost as if to spite Hiarcs. "Look what my bishop pair turned into!" :-)

Just chatting with Enrico, HIARCS was on 2 x 9775 @4.1 for this game.
Parent - - By Lukas Cimiotti (Bronze) Date 2008-06-21 20:37
4.1 GHz is difficult to achieve. It only is possible if you overclock FSB - the Intel Skulltrail board doesn't like that too much. Under normal conditions it is best to stay at a FSB of 400 MHz and only raise multiplier. Btw my "big" Skulltrail reaches up to 4.2 GHz, but it has next to no advantage over the "little Skully" that is currently in use. That "little Skully" has the advantage of very good hand-picked memory modules running at really good timings. But anyway - Rybka is much much better than Hiarcs - you would have won with your own computer as well - I think. :)
Parent - - By Nick (*****) Date 2008-06-21 20:43
Your machine is truly awesome Lukas :)  Rybka on it is slicing thru the competition.

Enrico says his ambient temp is 21-22c and his cpu's run at under 50 full load (2 apogee gtx waterblocks). Mult x FSB = 10 x 410.  I can't recall if your Big Skulltrail is on water or air?
Parent - - By Lukas Cimiotti (Bronze) Date 2008-06-21 20:50
My big Skulltrail is on water (2 Apogee GTX waterblocks ;) ) and a Mora2 Radiator (not Morra ;) ) with 8 12 cm fans (max 9).
I didn't read anything about that tournament on Hiarcs Forum - now I understand why :)

Round 7 against Sjeng looking reasonably good, Rybka made a > +0.5 book exit and is currently evaluating +1.04 at move 12

TimmelJ(64): Rybka - in the middlegame,,,the way it tied up Black's pieces...

Sjeng bites the dust, comprehensively outplayed.  Rybka 7/7.

I must admit that as an unregistered ICC user (who cannot kibitz or whisper or even send messages to people) it is a bit frustrating with all the people kibitzing "OH LOOK Rybka is at +4 but Sjeng is at -4, clearly one of the evaluations must be completely wrong!!11". :-)

/* Steinar */
Parent - - By Dark Horse (***) Date 2008-06-21 21:18
arent each of the evals from the engines point of view ? so if Rybka says +4 and Sjeng -4 then it is the same thing ?
Parent - - By Sesse (****) Date 2008-06-21 21:25
Yes, usually. (Some of the engines, like Crafty, differ, though, probably for using a different GUI or protocol.) The problem is that people don't seem to understand this, and the commentary thus becomes, err, less than intelligent. And as an unregistered user, I have no ability to communicate with these people...

Diep-Rybka. Rybka out-booked Diep by quite a bit, giving it five more minutes on the clock and a roughly equal evaluation as black. At some point, Diep sacrificed a knight (against a pawn) in what looked like an attempt at an attack, but then its evaluation suddenly dropped (from about equal to -1.8) and now both engines seem to think Rybka is winning (+3.30 for Rybka, -3.532 for Diep).

Edit: It should be mentioned that Diep is running on quite inferior hardware (dual Athlon MP 2600+) by modern standards. That alone makes it really hard to try to challenge the eight-core monster used for Rybka :-)

Edit 2: Yet, it saw the mate in 17 while Rybka was still searching at depth 8. Sounds a bit weird to me. But 0-1 and perfect score for Rybka the first day. Congrats!

Thanks for the games. Looking at the website I am not totally sure, is Rybka running on 4 cores and Hiarcs is running on 8 cores?
Parent - - By Nick (*****) Date 2008-06-21 15:54
We have quite a complicated set-up, but Rybka is on 8 cores @3.8 (Lukas' "Little Scully" machine, he can tell you more about it I guess) and I believe that HIARCS is also on 8 cores as per the ACCA website.
Parent - - By M ANSARI (*****) Date 2008-06-21 22:10
Good results guys ... seems like a cake walk for Rybka. I am a little confused why Hiarcs 8 is playing ... or is the newest Hiarcs playing?  And I guess now the standard hardware for engines to be competitive must be 8 cores.  8 cores overclocked really are a big boost for chess engines and the Skulltrail platform is perfect for chess.  I am surprised of the 4.1 Ghz ... how do you overclock the memory on the 5400XS ... I couldn't find that option in the BIOS.  I managed to get 4.2 Ghz on air ... but it is not 100% stable (although almost).  I guess maybe with lapping and using better HSF it is a very reasonable goal.
Parent - By Nick (*****) Date 2008-06-21 22:13
Hey thanks Majd, they were using the latest development version of HIARCS.   Perhaps Lukas can address your hardware questions, I think 4.2 on air could be pushing it for 100% stability?
Parent - By Lukas Cimiotti (Bronze) Date 2008-06-22 07:41
Some memory modules work at 410 MHz, most don't.
In my 2 D5400XS boards I use handpicked modules that run CL 4-4-4 at 400 MHz. This should be faster than CL5-5-5 at 410 MHz.
I didn't reach 4.2 GHz on air but with good water cooling it worked, but VCore was too high (1.45V). So I returned to 4.0 GHz.
Parent - - By Nick (*****) Date 2008-06-22 07:46
Also Majd, did you ever get your custom dual phase running on your Skulltrail?  If so what ghz did it manage?
Parent - - By M ANSARI (*****) Date 2008-06-22 08:04 Edited 2008-06-22 08:08
Oh yes ... I got to 5.2 Ghz ... but really I was only able to be 100% stable at 4.8 Ghz (I will email you the Fritzmark pix).  I had tried two different insulation methods on the CPU's ... one of them was 10C better so that probably slowed things down a bit ... so I took it all apart to redo both processors equal... I should work on it in a week or two and this time I hope to get my earlier goal of 5 Ghz on 8 cores stable.  The idea is to get this performance 24/7 and not simply to benchmark.  I am pretty sure I can get 5Ghz very stable as the design of the phase change I did had absolutely no problem keeping temps at the highest loads (2 x 1hp compressors versus Vapochill LS 1/3hp) ... I think it only dropped like 3C on load versus the Vapochill which would drop 20 or 30C.  At 4.8 Ghz the Fritzmark was 42.92 and something like 20600 knps !!! Also on Playchess some people were telling me I was getting more knps that a 16 core system with Zappa when I used it in a non Rybka tourney there.  It is a monster indeed.

As for the memory ... I used Mushkin memory which seemed quite good and can run perfectely at 4 4 4 12 ... but I did not see any performance difference.  I used a laser temp gun on the MCH ... and boy that thing gets really hot.  I do think there is a big pefromance gain to be achieved by sub zero cooling the MCH and memory modules.  But again this would make the project very complicated ... maybe I could watercool the MCH ... and the memory modules instead of phase cooling them ... we will see.  Already I am thinking of Nehalem.

Best regards,

The Games are on ICC - If you can figure out what numbers they are.  If you so - reply.

"observe Rybka" (or shorten "observe" to "ob") and you'll get her game. If you are registered, you can also "follow Rybka"; otherwise there seems to be no good solution except to hammer. :-/
