PVS are identical for me using the stockfish bench command. I'm going to try a GUI as Ingo did and see what happens

The interesting bit for me is

32-bit compile
Time: 4921

SSE42
Time 4701

GCC SSE42
Time 3611

The 32-bit compile is only approx 5% slower than the normal 64-bit one. In all 3 cases though, 5416292 is nodes searched, and the PVs are identical.

Hello Zlatin.

could you please run

Code: Select all

./stockfish bench
from the command line and see what searched nodes you get? You should have 5416292.

Thanks
Hello Marco,

Where must type this command?

Best wishes
Please take a look at this post. If you do not know how to change directory in command prompt, I recommend you the following: right click on the folder where the desired executable is and select something like 'go to command prompt', then type what I said in that post. Good luck!

Regards from Spain.

Well, the Stockfish bench command is suspect I think. In a normal GUI, currently the normal SSE42 version shows 1286 kn/s and the GCCSSE 1260 kn/s. Not the dramatic difference that the bench command shows.

And the PVs *are* different in a GUI.

Since the 'bench' test reported same node counts I'd assume the 2 binaries are 100% equivalent.
Yes, bench is giving identical results on my AMD as well

the Intel compile with 1255515 nodes/s and the "normal" compile with 1155352 nodes per second. The "Intel" Compile is about 8 to 9% faster ON AN AMD then the normal compile. (Remove the normal compile, no one needs it)

1) From command line or from GUI ?
2) Number of threads set or let SF to choose automatically ?
Classic GUI, both engines set to 1 Thread. Test run at the same time on the 6 core machins with 256 MB Hash (IPON conditions)
mcostalba wrote: 3) What command did you give ? depth limited, time limited, infinite ?
Just switched on "analysis", waited a minute and switched off manualy. I repeated that just a minute ago and get the same result (see above). Most striking is not the different speed but the different selective depth - and again this is reproducable!

As I used a GUI I am abolutly sure (expecialy with this GUI) that both engines got the same commands.

I'll wait a few days with testing :-)

Same here, in GUI the speed difference is much lower than the 8% from the bench and the PVs ARE different.

I agree with Ingo, with the Shredder 12 GUI and the AMD Phenom II X6 I'm seeing the same behaviour as him.

It is not the Phenom2. On an i5 I have the same odd behaviour.

Interesting is, that the GCC Intel compile is a bit faster, but the "normal" compile is faster in reaching a certain depth.

There is some work to do in the version :-)

with a simple 'bench' you can verify functionality is equivalent. For a guess about speed it is better to test with

Code: Select all

./stockfish bench > /dev/null
so that console output time is not included.

Did you run from starting position ?

Interesting - in the GUI, the PV for 32-bit and the PV for GCCSSE are the same. It is the normal SSE42 version that is different
