Zappa Mexico (8 cpu) vs Top free UCI engine

[Daniel Charles]

Engine testing condition

New Zappa Mexico 8 cpu vs 10 top free UCI engines
CPU 2 Xeon 5365 (8 x 3Ghz)
Time 4 Mn 2s
128 Mo , 512 MO for Zappa Mexico 8 cpu, 512 Mo For Glarung (4 cpu)
Egtb 3,4,5
Book perfect9.ctg
Gauntlet 10 games vs 10 Top free UCI engines
Total Games 100
score 74.5 %



Zappa Mexico is Very impressive on 8 CPU (just look at the match RybkaSMP vs Zappa Mexico!!)

That s why I decide to test it on my 2Xeon 5365 (8CPU 3ghz)

Zappa was able to score 74.5 % vs 10 top Free uci Engine!!! (and this is just The 32 bits version)

It managed to score positive record vs all opponent (only Strelka draw it, I was alittle bit surprise )

Toga,Strelka and Glaurung SMP (it was on 4 CPU) did very well vs Zappa Mexico (A top 2 commercial engine )

This is the first Time I saw a Top Commercial engine other than Rybka that could beat easily the top 10 free UCI engine ...

It was a big surprise to see Zappa Mexico score 80 % vs Free Rybka 1.0 (A top 3 free engine , maybe the best free engine).
It gave a chess lesson to others free UCI engine (95 % vs Pharaon !!! 80 % vs Fruit 2.3.1, 80% vs Spike 1.2 ...)

Hi Charles,

I'm absolutely convinced that Toga II 1.3.1 would fare better than 1.2.1par. On a single cpu Pentium 4, I ran a 32 game match with Toga II 1.3.1 vs Zappa Mexico, Toga won quite convincingly with a score of +14-7=11.

[Daniel Charles]

probably Toga has his chance in a match 1 cpu vs 1 cpu.

However Antony Cozzie is a specialist for SMP Chess engine ... And looks like that with 8 CPU , Zappa Mexico scale very well and is simply in the top 2 commercial engine on big hardware ...

It managed to score an impressive 74.5% vs very strong Free UCI engine

I just want to say wahouuuu ....

[Vinvin]

Could you estimate the speed up nodes/sec on 1 CPU vs nodes/sec 8 CPUs on your machine, please ?

I'm a bit deceived with zappa 8 cpus (50% against strelka 1cpu ???).

Anthony should work more to improve Zappa 1 cpu then he could get +100 elo on all CPU configuration

This is true, however, I just don't see the point of pitting it against weaker, older versions of programs. At least use the latest free versions, it would give a more accurate depiction.

You talk as if there is a 100 point difference between 1.2.1 and 1.3.1.

Nice test, But I don't think it's fair putting 8 core monster versus 1 core engines. (AFAIK only glaurung and maybe naum supports MP). So this test doesnt prove much becuase of the hardware differences. A surprisingly good result for Glaurung. I don't know why people still tet Strelka wasting time on it after its validated as a clone already.

Zappa on monster hardware is a beast no doubt about that. when these machines become more affordable its going to be interesting to play games with such high level and speeds.

Thanks,

Hello Daniel,

Congratulations for your new hardware''CPU 2 Xeon 5365 (8 x 3Ghz)''
I wonder which smp engines do not support 8 threads ?!

A such information will be very useful !

Thanks,
Sedat

Hello Sedat

Thanks for your neutral books .ctg .
I still test eng vs eng 80% with some of your neutral book

Good question about chess engine that could support fully and scale well with 8 cpu ...

For sure Zappa Mexico and Rybka SMP (they were running both on 8 cpu at Mexico )

for commercial engines I could not answer , because I don t have a lot.
Zappa was on my very short list to buy ... Like Rybka 3 will be ... beside that I don t plan to buy a lot of commercial engines .

However I will test free UCI/WB engine SMP like Scorpio,Glaurung,Deep Patzer, Crafty, Smash SMP ... we will see if they are doing better on 8 T ...
and which one scale better from 1 to 8 T

Thanks

Daniel

If not a 100 point difference, then pretty massive, 50 elo minimum. 1.3.1 gets better results, bar none. We might as well put Rybka 1.2 in a match vs Zappa Mexico to see which engine is better.
