anyone have some good stretches for a pulled lower right back muscle?
Parent - - By Cole [us] Date 2012-10-23 09:01
Of course you are right.   It's just that very few people have a dual Xeon setup to make it a real heavy weight fight.  Whatever you decide I thank you for considering it.

I'm thinking of going the dual E5-2620 route  then upgrade to 8 cores when I get the $$.

If you're going to do that I'd probably buy one e5-2620 rather than 2.

I'm also wondering if I should also wait till march or april for Haswell. I heard they are taking some kind voltage regulator off the motherboard and putting it on the die itself. I couldn't imagine it would affect overclocking because of the huge fan-base this demographic has with intel and mobo manufacturers i.e.(buying more expensive chipsthat are unlocked and enthusiast boards) they would be alienating. Just a thought.

If you wait for Haswell in April that will be the desktop format - it won't be available in the Xeon format then.

Well my machine is also available to rent most of the time.

Anyway, if there's any news I can share, I'll let you know

im curious,would houdini 3 be as strong as the rybka cluster if givin the same amount of time per move?   example.....100 games at 30 sec per move for each of them, who would come out on top?

i would like as many opinions on this as possible

All you will get is opinions until someone rents it and tries it.

Or until you get a match played between the Rybka team and the Houdini team.  Even then, you could have virtually anything happen.  In a recent SSDF match between Deep Fritz 12 and Deep Rybka 4, the match was tied after 10 games until Rybka started running away with it.

Yes, we need 100 games....so someone with deep pockets!

A game was adjourned in the position shown in the diagram below. White sealed his 36th move. Black has a good drawing chances (I think) but White (being a considerably stronger player than Black rating-wise) is likely to punish every Black's mistake. Both players have about an hour for the next 28 moves. May I ask what would (in your opinion) be the best approach for Black (to try to get a draw)? The game is going to be resumed on Tuesday the 1st October at 7.30pm GMT (so I would need your advice by then). Thanks.

P.S.

May I ask why (as it would seem) Rybka Cluster 188 Cores did not show a 32 ply (or longer) line (it would appear that it shoved only a 16 ply line)?

It is set up to display a pv length of at most 14. It's adjustable.

Thanks for the reply.

May I ask if it is adjustable within Fritz chess interface when using Rybka Cluster in ChessBase Chess Cloud (or it is an internal setting)?  Thanks.
Parent - - By Lukas Cimiotti (Bronze) [de] Date 2013-09-30 17:47
It's an internal setting in the cluster config file. Only I can change it, but it's no big deal.
Parent - By robertj (**) [gb] Date 2013-09-30 17:48
OK. Thanks.
Parent - By robertj (**) [gb] Date 2013-10-02 10:23
Drew the game and the game continued almost exactly as Rybka Cluster 188 Cores suggested 36.Bf5 Bg6 37.Bxe6 Kxe6 38.b4... :smile:

Can someone please suggest powerful hardware t be unbeatable at online chess?

16 core xeon? 
16 core AMD bulldozer?

How much RAM?
Parent - - By Fulcrum2000 (****) [nl] Date 2013-01-03 14:37
You will never be unbeatable online even with top engine and top hardware. :wink:
Parent - - By yogeshdg [in] Date 2013-01-03 16:44
Yes sure. I meant do you think a  16 core intel xeon is enough to beat  a i7 6 core or amb bulldozer 16 core?
Parent - By Fulcrum2000 (****) [nl] Date 2013-01-03 19:16
If it has a decent clockspeed yes, it will beat the others most of the time (with same book, engine etc). Maybe something like a 60 ELO advantage.

Lukas,
I recently bought Chessbase 12 (and Deep Fritz 12) specifically to use the Engine Cloud, and especially Rybka Cluster.
I got a valid Playchess.com user name and can log into Playchess.com.
However, whenever I try to use a Cloud Engine, I get one of two error messages from either CB12 or DF13:
"The maximum number of accounts has been reached" or "Serial # invalid".
   Chessbase does not respond to emails. I was hoping you might know something about this problem.
                      Thanks, CMA

email info@chessbase.com

They are the only people who can help. The guy you need help from is Steffen Giehring so address the email to him and am sure he will help.

It can take a few days as they can get really busy with number of support emails they get on a daily basis.

iv  rented the rybka 140 core and pitted it several times against houdini  32 core and sad to say rybka just keeps running out of time.  that is in blitz however i have yet to run a match under standard controls 2 hours /40  etc. the rybka 140 core is impressive  calculating 180 million moves per second but it doesnt phase houdini 3. il have to try some matches at  2:00:00/40. when I do  ram my visa into chessbase again, rest assured those battles will be posted on you tube.
Parent - By Bloodbane (**) [fi] Date 2013-01-24 05:39
Rybka runs out of time because the moves and analysis need to be transmitted from your computer to the cluster and back and this takes some time. Something like 5+3 or 5+5 should prevent timeouts.
Parent - By suj (***) Date 2013-02-12 10:57
houdini 32 core? where did you play ?
- - By Dionmarinos [ca] Date 2013-01-24 14:18
ya it must be the bottlenecks of all those connections.
Parent - By suj (***) Date 2013-02-12 10:51
i would say you are better off playing games with +5s  increments.

Is Rbyka Cluster in Chessbase cloud suitable for correspondence chess? I'm asking this, because I'm seeking a powerful computer and an engine for my cc play.
