Booot 6.1 released

[booot]

Hi!
Here is new version of my engine:
1. Booot finally is smp engine! New uci parameter 'Threads' appears. I made simple LazySMP algorithm - seems it works fine!
2. Lots of optimizations, bug fixes etc.
3. Lots of eval knowledges added. Eval function was redesigned.

My quick self-test shows >50+ elo points improvement on single core.

What cpu do you have ? I havent implemented smp myself yet but do you get the 50+ elo improvement from hyperthreading on one physical core ?

I have got 50+ elo points improvement (according my tests) on single core comparing with last released Booot 6.0.2. I have I5 processor (4 cores). When i tested this new version with different number of cores turned on i have got this results:
2 cored Booot is about 65 elo points stronger compared with single core
4 cored Booot is about 110 elo points stronger compared with single core.

I am not sure.. Delphi has poor set of compiling options.
