Deep Rybka 4 - Houdini on fast hardware

[beram]

For those interested,

Deep Rybka 4 on my new fast hardware, is better than Houdini (though not so much)

Code: Select all

AMD Phenom II X6 1090T 3200 Mhz,(Fritzmark 23,1)
TC Blitz 2m2sec, 512 Mb Hash, 100 (Nunn2+privatbook) positions
                             
1   Deep Rybka 4 SSE42 x64   +28/=57/-15 56.50%   56.5/100
2   Houdini DEVEL x64 8_CPU  +15/=57/-28 43.50%   43.5/100

Apparently Houdini performs worse on AMD processors compared to intel. I have AMD as well and it's not topping my tournaments but it's comfortably leading my intel laptop tournament in 32 bit OS. Btw a question you have six cores, what version you used 4 cores or 8 cores? Did you make sure they used same number of cores?

Hi Taner, to me it looks that it performs better on 32 bit Windows environment and secondly on fast hardware.
I let it run with the 8 core version and both using 6 cores (checked also with task manager)

I just finished a first match of Houdini 1.02 (released yesterday) against DR4. Houdini won this first match 26,5 - 23,5
I am letting it run a second 50 games Nunn2 match now will update this later on.

Code: Select all

AMD Phenom II X6 1090T 3200 Mhz, F12 gui (Fritzmark 23,1)
TC Blitz 2m+2s, 512 Mb Hash, 50 privatbook positions, ponder off, both using 6 cores
                                   
1   Houdini 1.02 x64 POPCNT 8_CPU  +12/=29/-9 53.00%   26.5/50
2   Deep Rybka 4 SSE42 x64         +9/=29/-12 47.00%   23.5/50

Run 1000 games at that TC and you may be surprised.

Best,
Gerold.

Houdini is a very strong engine but on the other hand it is reported that DR4 scales much better than anything else so it's anyone's guess.

But I agree that 100 games is too few. I suggest shortening the time control and maybe increase number of games to something like 300-400.
