Looks like Deep Sjeng wins cct12

[Daniel Shawul]

Totally agreed. If you provide the other engines 128 cores, they would just sit on it. So there is no reason why sjeng should be penalized for out incompetence. Infact he should be thanked for participating with such a good hardware. It gives the tournament good advertisement, good motivation for the rest of the group to draw/win it etc..
As to Peter, he runs the tourney as smooth as possible, even accomodating some stupid late comer arriving an hour late Thanks a lot. I had a lot of fun myself throughout the times I managed to stay awake. I hope more participants will join in for next year.

cheers
Daniel

Actually the latest 64bit Win 7 has been a really nice OS. I usually don't like to praise a MS OS, but really I think they got their act together here. The OS is fast, sleek with a small footprint and very stable.

Totaly agreed here....last week I made the big step to purchase and install Windows 7 x64 Ultimate and I must say that it's a fine product....fast,stable and error free....almost,I haven't seen one yet to admit

Agreed.

Respect to GCP and his Sjeng for winning. Are Sjeng and Rybka the only two engines that run on standard-PC Clusters?

Looking at the games though, I enjoyed some of Hiarcs wins more. Just a matter of taste.

You forgot to mention it is using 128 cores cluster. On the other hand, It would be a complete failure, if it did not win the tournament...

Considering that huge clusters have more often not won, than won, it is a very nice victory. A hearty congrats to Gian-Carlo, and to Peter Skinner for a great tourney once again!

Yes, that is indeed true. Historically, clusters haven't performed well enough to win. I used to have discussions with Steve Otto about this at work (he was involved with WayCool). He said he wished they had written a good single proc chess program before moving on to a super computer version. Seems that is what all of the past did - they jumped straight to a super computer. Now, the successes are coming from programs that started as single proc programs.

On the issue of practically cheating, I say bull. I have a version of Telepath that runs on a cluster. It took quite some time to code, test and tune it. There are considerable issues to over come in cluster programming. Some take time, others take large numbers of CPU's. I need more CPUs before I run the cluster version in a tournament. So, I know what kind of effort it takes.

So, Hooray for GCP.

AFAIK, there aren't any open source cluster programs. That is good. If you can't read the manuals and figure it out for yourself, then you aren't capable enough to do it.

Indeed. I was just playing through the pivotal and spectacular Hiarcs-Sjeng game. I'm curious, just how far into the game did Sjeng see clear compensation for the sacrificed piece after 25... Rxa2? In this game, I love how the Rb8 was left en-prise for fifteen moves. Hiarcs' later equalizing shots of 61. b5 and 62. c4 were also very impressive. How much of the resulting KBNR-KBQ endgame was determined by endgame databases?

This would be a game worthy of publication with deep annotations.
