Which Toga for this tournament ?

[Spock]

Following on from my last 90+30 tournament
http://kirr.homeunix.org/chess/discussi ... f=7&t=3026


I'm going to do another one soon with 8 strong free engines

Hardware etc
Dual Core Opteron 185 2.6GHz
Arena GUI
90'+ 30" with ponder on
512MB hash each engine
5-men tablebases
book HS-12moves.abk
round robin, 4 rounds, 112 games

Engines will be
Rybka 1.0 64-bit
Fruit 2.3.1
Toga (which version....)
Spike 1.2 Turin
Glaurung 2.0.1 64-bit
Naum 2.0 64-bit
Bright 0.2c
Frenzee Dec07 64-bit

Any alternative suggestions welcome. I'm still trying to decide on the Toga version, there are so many now....

.....and it's based upon testing at long time controls,this is the version which is climbing fast my rating list toward the Rybka's highest section

Ah - now that's what I call a top tip !!

[Spock]

Hmm... and which compile for my AMD64 Opteron ?

The downloads that I have are

TogaIIv3.1.2SE_P4_SSE2.exe

and the Denis Mendoza ones
Toga II 3.1.2SEp3.exe
Toga II 3.1.2SEp4.exe

I like it really when authors keep it simple, one compile fits all...

EDIT:
Oh, and these...
Toga64_SSE2.exe
Toga64_SSE3.exe

[Spock]

Well I tried them and they all work

This one is fastest on my machine

Toga II 3.1.2SEp4.exe

So I'll use that. But the differences are negligible, barely 5% between fastest and slowest

[Ovyron]

Toga II 3.1.2SEp4.exe

Could you please use these settings? (Chekov by Eelco de Groot):

[OPTIONS]
Verification Reduction=6
Futility Margin=125
Extended Futility Margin=325
Delta Margin=55
Quiescence Check Plies=2
Material=102
Piece Activity=103
King Safety=125
Pawn Structure=105
Passed Pawns=105
Toga Lazy Eval Margin=245
Toga Extended History Pruning=true

They performed better on my computer and in matches made by NATIONAL12 (from the Rybka forum) relative to the original but they haven't been tested enough, so it would be very interesting to see them play if possible

[Spock]

Unfortunately the tournament has already started

[Ovyron]

Ok, maybe next time
