Firenzina

http://dgusev.cs.edinboro.edu/GameDev/Chess/firenzina.html

Firenzina is a free, open-source UCI chess engine by Yuri Censor (Dmitri Gusev), a clone of Fire 2.2 xTreme by Kranium (Norman Schmidt).

Firenzina 2.2.2 says MSVCR110.dll is missing.
I found the file on the internet, and installed it into my windows, but I still get the error.

Thanks, what about Firenzina 64bit (not-popcnt) ?

unfortunately does not work for AMD ....

What's new in Firenzina 2.2.2?

Try this new MT compile that does not require DLLs from Microsoft Visual C++ 2012 Redistributable Package (x64):
http://dgusev.cs.edinboro.edu/GameDev/Chess/Firenzina_2-2-2_xTreme_popcnt_sse4-2_intel13_MT_x64.zip
I will release less restrictive compiles (no-popcnt, x32, etc) soon. I just need to test them as I make them.

It's a clone. New _mm_popcnt_u64 intrinsic replaced the old hardware popcnt, which, rather counter-intuitively, was slower than the software emulator of popcnt. The new hardware popcnt is faster, as it should be. Also, now you can have up to twice as many threads as CPUs. Not that you would want to, but you can.

Your test must have been flawed. There are several possibilities:
(a) You used Jose Velasco's no-frills Firenzina compile capable of running on my Intel Core 2 x64 Quad at work. (It doesn't support SSE4.2.)
(b) You forgot to set the number of threads to be the same for both engines. For Firenzina, set Max_Threads to be equal to the number of CPUs (say, 8 for a hyperthreaded Core i7 Quad).
(c) All of the above.
(d) You configured RobboBases for one engine, but not for the other one. (This is highly unlikely.)
I posted the results of the initial (02/25/13) Firenzina compile long time control 40/40 match against Stockfish 2.2.2 (sse42_ja_intel) at 6 threads for each engine at http://dgusev.cs.edinboro.edu/GameDev/Chess/FirenzinaMatch1vStockfish222_nunn_40-40.zip

Will do, as well as a compile for x32, which others have requested.

Are you kidding me? the test is 100% accurate/correct!

Your compile does not work, so i used his compile.

No.

Very funny.

That explains it, thank you. What equipment are you using? If your computer has a modern Intel processor that supports SSE4.2 and hardware popcnt, then you should be able to run my /MT compile that I released yesterday to remedy the problem. It's available at http://dgusev.cs.edinboro.edu/GameDev/Chess/Firenzina_2-2-2_xTreme_popcnt_sse4-2_intel13_MT_x64.zip
The initial /MD compile required DLLs from Microsoft Visual C++ 2012 Redistributable Package (x64). I overlooked it, because, as a developer, I have the DLLs, and I didn't realize that they're uncommon. I ran a 500-game 1/1 match to quickly make sure that the /MT compile is no weaker than the initial /MD. The match ended in a tie today, +75-75=350, the kNodes/sec numbers were similar. The /MT executable is noticeably larger, due to static linking.

Compiler capabilities vary quite a bit, see some performance test results at http://software.intel.com/en-us/intel-parallel-studio-xe . Jose Velasco's is an MSVC compile.

Thanks for the new engine Yuri. Keep up the good work.

My sincere apologies and big thanks for helping catch the mistake! I was working on generic 32-bit and 64-bit compiles simultaneously and accidentally mixed them up. Neither has been linked to the Firenzina website yet. Will fix.

Please try again! The link is the same,
http://dgusev.cs.edinboro.edu/GameDev/Chess/Firenzina_2-2-2_xTreme_x64.zip, but the archive contents changed. One 64-bit compile is LP, the other one is NLP (No Large Pages). Both are no-popcnt. I would like to know if they run okay on 64-bit AMD machines. (I don't have one.)

Thanks Yuri.

Thanks for testing! +7 Elo against the factory compile is not bad for a generic no-popcnt compile, where the new intrinsics don't play a role.

Compile Firenzina 2.2.2 for Mac OS X?

can we have a 32 bit version of the engine???

I don't have a Mac, but if you or others are interested in doing that, you're most welcome!
