Stockfish team is doing a Herculean job and soon Stockfish engine will exceed Houdini 3. What is, then, the version of stockfish best to date?
Thank you for your attention

Hi Waldemar

I have a doubt! Are these versions that supports Syz based from the new engines arisen in the development site?

Hi Waldemar

The Original DEV Stockfish code has been aligned with the syzygy tablebase code. So, you are still playing the super strong Stockfish engine (no clone) but with the added benefit of syzygy 3-4-5 tablebases and 6 piece if you are lucky enough to possess 32 gigs of RAM or more! (jealous)

as is.

On my initial tests this looks like the strongest yet, halfway through my 100 game test with Houdini3 the new Stockfish is +5 ! Best previously was 091013 which was +2 at this stage, and 151013 which was +1. Cheers - Eric

Hi all

Has anybody compared different compilers ?
I mean benchmarking stockfish and making it more faster.

We have now Mingw compiled stochfish nice and fast in http://abrok.eu/stockfish
And even with syzygy end game tables smile 

How about intell icc and micro$oft vs2008/vs2010 ?




Zimmy

descriptionStockfish - Page 6 Emptycompilers....

OK

vs2010 express and vs2012 express do not have PGO optimization
No idea to benchmark without good optimization tools

So - MinGW64 is my tool in linux64 and win7x64 smile

Timestamp: 1383292575

Set timer to a fixed interval

And remove a complex (and broken) formula.

Indeed previous code was broken in case of TC with big
time increments where available_time() was too similar
to total time yielding to many time losses, so for instance:

go wtime 2600 winc 2600
info nodes 4432770 time 2601 <-- time forfeit!

maximum search time = 2530 ms
available_time = 2300 ms

For a reference and further details see:

https://groups.google.com/forum/?fromgroups=#!topic/fishcooking/dCPAvQDcm2E

Speed tested with bench disabling timer alltogheter vs timer set at
max resolution, showed we have no speed regressions both in single
core and when using all physical cores.

No functional change. http://www.abrok.eu/stockfish/
