Thanks, looks good. Any JA compile ?
Dont forget to 'get ideas from Robbo code' to get a big boost as stockfish 1.7

Main changes:
* SMP support (max 8 threads). If hyperthreading is turned on, please set number of threads to number of physical cores.
* Support of "searchmoves" UCI option (useful for IDEA)
* Decreased middlegame pawn value, but much larger passed pawn bonuses
* Added some endgame heuristics (KRPKR, KQKP, opposite colored bishop endings)
* Somewhat slower NPS, but faster time-to-depth
My own single thread testing against Critter 0.52b shows 42 ELO improvement (with error margins +-7). I don't have a precise figure about performance vs. other engines.
Enjoy,
Richard
Seriously, I've been waiting an MP release since like 0.42 or something.
Protector 1.3.4 JA 64-bit,
Crafty 23.2 JA 64-bit,
Scorpio 2.5 JA 64-bit,
and bright-0.5c will likely be its first opponents. Maybe some version of Toga also.
Congratulations,
Peter

Re: Critter goes SMP (version 0.60 is released)
Thanks. The CCRL list helped . It's kinda tough to find some decent amateur SMP engines, so I might through in a stronger engine (Thinker, spark, or Shredder probably) on a single core.Graham Banks wrote:Sounds like a sensible selection of opponents.alpha123 wrote: Protector 1.3.4 JA 64-bit,

Re: Critter goes SMP (version 0.60 is released)
I'm sure this one is going to jump in CCRL's top 10 on 4 cores. And sorry if it's an underestimation.
Nicely done!

Any plans for a linux compile? I - and I bet many more people here - would love a linux version. (Or maybe the source...)
Anyway, thanks for the engine.

I've been waiting for this.
I'm going to run a Gauntlet on my 4.0 GHZ I7-920. Look for the crostable and a link to the games on the "Computer Chess Club: Tournaments and Matches" forum, sometime before the weekend.

Hello Richard!
Looking forward to test your engine.

Re: Critter goes SMP (version 0.60 is released)
Hi, Richard!
Why Critter needs gtb.dll?
In uci options seems that gtb use are not allowed..
Are there any site to download gtb.dll?
Or are in alpha state?
Thanks in advance

Re: Critter goes SMP (version 0.60 is released)
There is some unportable windows specific code which needs to be rewritten first (mostly the threading stuff). But the windows compile runs just fine under linux + wine.nepossiver wrote:Any plans for a linux compile? I - and I bet many more people here - would love a linux version. (Or maybe the source...)
