"Shared analysis doesn't work with more than 3 processors".

"Shared analysis doesn't work with more than 3 processors".

Possible ! I don't have a such machine !

"Shared analysis doesn't work with more than 3 processors".

Even with the ChessBase recommended (for text-file Rybka 3 32-bit .uci_b)?:

[ENGINE]
Parameter=%PID 1
[OPTIONSA]
Preserve Analysis=true

Yeah, but you are still right. On a Quad it will only use 3 cores. Also if you kill shared analysis your main analysis engine will not go back to using 4 cores, the main engine will be left using just 2 cores. All this even with the changes to the (b) engine uci_b file.

Yeah, seems the max is (CPUs / 2) + 1, so on an octal Shared analysis can only use 5 cores?!
