Hello:

In the command prompt, go to the path where SF is saved . Then type the name of the executable (without .exe) and this:

Code: Select all

stockfish-222-32-ja bench 128 1 12 default depth
128 means 128 MB of hash; 1 means the use of just one core; 12 means analysis up to depth 12; default and depth meanings can be found in benchmark.cpp file.

My modest result, in an Intel Pentium D930 (3GHz):

Code: Select all

===========================
Total time (ms) : 15047
Nodes searched  : 5447426
Nodes/second    : 362027
5447426 nodes searched is the correct number. Other number tells you that the executable is corrupted in some way, if I remember correctly. I found the info (because I also did not know how to do this test) of how to run benchmark command in a topic from Rybka Forum:

StockFish 1.7/1.7.1 Benchmark

I hope I had been enough clear. It would be good if you post the results of your great hardware!

Regards from Spain.

Here's a template, but for linux/OS X

Code: Select all

./stockfish bench 512 8 16 default depth
(Assuming the executable is named stockfish in the current directory.)

Sets the hashtable size to 512, 8 threads, default list of test postions, each searched to depth 16.

Code: Select all

stockfish-222-ja bench 256 2 16 default depth

In the above case you are asking stockfish to setup an
Hash Table of 256MB, start 2 Threads that search up
to depth 16 on a set of default positions with a
"fixed depth" search.

Stockfish’s new signature is: 5447426
(stockfish-222-64-ja.exe bench 128 1 12)

Total time (ms) : 5366
Nodes searched : 5447426
Nodes/second : 1015174

I was clear in my question, but no answers are clear.

If I find the exe, then can I open the exe and then type a command?
do I open with a right click and then admin?
Do I have to go to accessories, command window first?
what is max hash

then what step by step.

thanks

Do you know how to navigate to the stockfish directory in the command window?

Suppose the .exe program is is c:\stockfishfolder
and the executable is stockfish-222-32-ja.exe as Jesus mentioned

go to
start --> all programs --> accesories --> command prompt
(this may be slightly changed depending how the system is set up but it is not the only option http://www.sevenforums.com/tutorials/94 ... rompt.html)

type
c:
cd \stockfishfolder
dir


you should see stockfish-222-32-ja.exe listed.

Then type
stockfish-222-32-ja bench 128 1 12 default depth

as it was mentioned by Jesus

I do no have Stockfish and I am in Linux system :-) but I think this will help you.

Miguel
