a test of how well cm11 scales from one processor to two

[ozziejoe]

I took a look at how well the king scales from one processor to two. It looks like it gets about 60 points, which I think is quite good scaling.

(Note: ratings of non-king engines not to be trusted since they only played the king and not each other; Note 2 ; I only used single processor version of rybka because the mp version would be much too strong)

Hi Joseph

Thanks for this interesting test - it is reassuring that the improvement seems reasonably consistent between different time controls and test conditions. Which version of Naum did you use?
