You have to take into account that there is time needed to load base position and score the game after playout. I remember that in my old tests it was around 180 cc per move.

Re: [computer-go] Digital Mars
Success! I was able to build on WinXP using Scons and minGW (with gcc4.3.3). Here's what (finally) worked for me: 1. Install Python 2.6.2 http://www.python.org/ftp/python/2.6.2/python-2.6.2.msi 2. Install minGW (using TDM's installer on empty minGW directory) http://downloads.sourceforge.net/tdm-gcc/tdm-mingw-1.902.0-f1.exe 3. Install SCons 1.2.0 http://prdownloads.sourceforge.net/scons/scons-1.2.0.win32.exe 4. add C:\Python26\Scripts\ to path (for scons.bat) 5. add C:\MinGW\bin to path (for g++.exe) 6. unpack latest version of libego http://github.com/lukaszlew/libego/zipball/master 7. edit SConstruct (CXX = g++.exe) 8. run scons.bat (from root directory of libego) 9. run build\example\opt\ego.exe (from root directory of libego) 10. report benchmark results The benchmark results for me were: 31.0417 kpps/GHz Hope this helps.

Re: [computer-go] Digital Mars
After I used a better MinGW build, with a newer gcc (the one Ben suggested), I
get must better results with no compiler warnings:
40.0609 kpps/GHz
Lukasz, the march options of native, i686 and core2 all worked and came out to
similar results with i686 being slightly faster for me.

We can run the binary on a system without cygwin if we provide
cygwin1.dll.
That is great.
Another good idea is mingw.

Re: [computer-go] Digital Mars
That seems like a good speed.
On my Intel(R) Core(TM)2 Duo CPU T5450 @ 1.66GHz, using linux and
the exact compiler libego was tuned for, I get 42 kpps/GHz.
On my AMD Athlon(tm) 64 X2 Dual Core Processor 5000+, using the same
compiler, I only get 37 kpps/GHz.

Lukasz, the march options of native, i686 and core2 all worked and came out
to similar results with i686 being slightly faster for me.

No too much :)
Can you try -march=i686 and -march=core2 (if you have core2) ?
And I was able to create a DLL like this:
C:\Libego\lukaszlew-libego-476a46885f80e1f4d83494bb632398b3974e901bg++

-frename-registers
46274.8727441 pps
SUCCESS! Thanks for everyone's help.
Here are the contents of exported.cpp:
This is almost the same as Benchmark::do_playout in benchmark.cpp
#include ego/ego.h

There's a big difference between kpps and kpps/GHz! For your system, you need to divide by two (and on my core2, divide by 1.66). For raw kpps, I think I had 70 on my core2 and 100 on the AMD64.

Re: [computer-go] Digital Mars
Just to add my 2c for the performance freaks. I've noticed that code generated by g++ 4.3.x was about 40-45% faster non-optimized when compared to previous versions of g++ (native linux platform). When optimizing code (-O3), 4.3 generated code that was 20% faster. This is probably the more relevant number for those that optimize their code anyway. Don't know about you, but I was impressed by 20% gain. If you already use g++ 4.3, pardon my interruption. But if you don't, you will be pleasantly surprised once you upgrade to it.
