Stockfish-1.6.2 Benchmarks for 1 to 8 Threads

[Joerg Oster]

Probably not a good idea. Just a first effort. I'll do some speed testing using the default positions in the bench command.

Well, this sounds much better.
I guess a set of at least 10 positions might give a first good impression.
But how do you change the options? Is there a way in changing them via command line?

Joerg.

Joerg.

I will compile 6 copies of Stockfish-1.6.2, identical except for the default value of Minimum Split Depth (which I'll set at 4, 5, 6, 7, 8, 9). (I'll make the max value for Minimum Split Depth equal to 9). I'll then run them in succession, invoking each with the bench option. I assume that the bench is run using the default values of the various uci options.

For reference, how does Crafty do on this hardware, NPS wise, with 1-8 threads?

Hi Luis,
I've try a little bit:

When i type immediately >stockfish-16-ja bench 256 2 16 default depth< (in a fresh) command line then it works.
I get:
Total time (ms) : 202238
Nodes searched : 337415986
Nodes/second : 1668410

but at the end >Press any key to exit< works not. I get no DOS-Prompt, i.e. no E:\UCI_Engines> and no exit.

I must leave the Dos-box by clicking the X in the right above corner.

That was the Failure (no Dos-Prompt) what happend in my 1st case.

I typed first only for fun >stockfish-16-ja< which gave an info-line (but no DOS-Prompt at the End), i don't aware of this.
Then i typed >stockfish-16-ja bench 256 2 16 default depth< and get >Unknown command< as in my previous post shown. Even the command dir no longer works.

Strange behavior. Is my command line faulty? Only in a fresh command line works >stockfish-16-ja bench 256 2 16 default depth<
My OS: W7 64-bit

The program was still running, awaiting a uci command. Try typing

stockfish-16-ja

at the DOS-prompt. After you see the info, try typing

uci

and hitting return. Do you get a long list of options? Then try typing

quit

, to terminate stockfish. Does the DOS-prompt return?

Strange behavior. Is my command line faulty? Only in a fresh command line works >stockfish-16-ja bench 256 2 16 default depth<
My OS: W7 64-bit

Probably not, but I don't know Windows.

[Joerg Oster]

OK, I expected to get this answer.
I have absolutely no experience in compiling a Program.
So I must do my testing by hand.

[Paloma]

Hi Louis,
you are right, it works! Many Thanks !!

[IanO]

I'm willing to help, but first I need to find a suitable GUI for use on my Mac. I have Sigma Chess (a fabulous program but now rather old), which doesn't allow time controls less than 1 minute. Any suggestions? I know Tord uses a Mac. Guess I'll do some Googling.

cutechess is very good I don't know if there is a version also for Mac.

Yes, it also compiles on a Mac once you obtain the Boost C++ libraries it depends on. I use Sigma Chess to run most automated matches, but I use cutechess for winboard engines (like Crafty) and UCI engines which don't load in Sigma (like Rybka+microwine). Cutechess's main limitation is its inability to use sudden-death time controls, but that would be easy to fix.

ExaChess can also host UCI engine matches, but it is more finicky about UCI support and has no interface to customize UCI parameters.

Also, search this forum for the big cutechess thread. I think someone posted Mac binaries.

Here are benchmark results for stockfish-1.6.2 using 8 threads, for Minimum Split Depth (MSD) = 4, 5, 6, 7, 8, 9.
Note that each run involves a 'default' collection of 16 positions. There are two runs for each value of MSD.

Based on these data, it appears that MSD=7 is perhaps the best choice for 8 threads. Note that Maximum Number of Threads
per Split Point is set to its default value of 5 for each run below.

I plan to run a match of 1000 games at game/40s between stockfish-1.6.2-MSD4 (the official version) and stockfish-1.6.2-MSD7.
I'll use cutechess-cli and Marc Lacrosse's performance.bin truncated at 10 full moves. Results tomorrow, I hope!
