Hello Dear Friends,

Honestly,i am surprised and impressed by the latest results of Houdini 2.0c Pro x64 12 Threads (HT ON)

Of course,for a better conclusion more games are needed...
But however,looking at the current results,still i don't expect the ELO performance to be in favor for HT Enabled
Some Notes:
-Since December 2011,SCCT Auto232 Participants are started to use 512 MB Hashtable size
-Houdini 2.0c Pro x64 1c performed approx.10 ELO better than Houdini 2.0 Pro x64 1c
-Houdini 2.0 Pro x64 4c performed approx.10 ELO better than Houdini 2.0b Pro x64 4c
In other words,Houdini 2.0c Pro x64 6c's expected ELO performance to be min 15 ELO stronger than Houdini 2.0b Pro x64 6c
And that means (as i mentioned before) Houdini 2.0c Pro x64 6c is expected to be approx. 10 ELO stronger than Houdini 2.0c Pro x64 12t


Let’s see, what will the HT ELO performance after more games…

Code:

Greetings,
Sedat


You are way inside the "noise window" here. You need tens of thousands of games, not a couple of hundred. This is likely the result of simple SMP non-determinism...
