From ReadMe
Gull 2.1 @ 17.06.2013
Evaluation weights are optimized with the use of automated tuning (source code included).
Gull's evaluation is no longer almost identical to that of Ivanhoe.
Minor search & time management & SMP efficiency enhancements.

On SMP & Hyper-Threading:
By default Gull limits the number of processes to the number of phisical CPU cores availible.
This is done in order to avoid ELO drop due to significant SMP search overhead at bullet time controls.
However for long games & analysis it is recommended to turn HT on and manually set the number of processes (UCI option "Threads")  
to equal the number of logical CPUs.

On the automated tuning (technical):
Tuning is done in two steps:
1. an estimate of the gradient is calculated;
2. line search is performed.
SPSA (just move a bit along the gradient direction instead of performing a line search) may also be quite effective,
though it's difficult to pick good parameters.
Fairly simple exit criteria are used for the line search. I don't employ SPRT because it's guaranteed to be optimal only for
elo=elo1 vs elo=elo0 hypothesis, whereas in this case we are interested in elo>elo0 vs elo<=elo0 test. However it's still possible
for SPRT (or some other test) to be better for some elo-elo0 values. Shouldn't be very difficult to run a numerical comparision
between various tests.

Very nice, lets see how much ELO gain will this version give to Gull over the last one

When I installed the 32 bit version of Gull 2.1 in my Arena Gui, got this error message:
" The program can't start because MSVCP110.dll is missing from your computer. Try reinstalling the program to fix this problem

Try this Visual C++ Redistributable for Visual Studio 2012

The Visual C++ Redistributable Packages install runtime components that are required to run C++ applications built with Visual Studio 2012.

I have made a new compile of Gull 2.1 with some changes in source.
A small test (1-core, 20 sec per game) shows +14 ELO ±20:

Code:

  Program                       Elo    +   -   Games   Score   Av.Op.  Draws

1 Gull 2.1 x64 Trap           : 2957   20  20   500    52.0 %   2943   55.2 %
2 Gull 2.1 x64                : 2943   20  20   500    48.0 %   2957   55.2 %

1 Gull 2.1 x64 Trap         : 2957  500 (+122,=276,-102), 52.0 %
2 Gull 2.1 x64              : 2943  500 (+102,=276,-122), 48.0 %

Gull 2.2: https://sourceforge.net/projects/gullchess/files/latest/download
Mirror: http://www.spaadyshare.com/386UAP15JGSS/Gull_2.2.zip
5-15 ELO gain in 1CPU ponder off mode is expected. More in ponder on and SMP modes.

just in the right time - I wanted to test Gull 2.1 smile 
Now changed to new Version!
