Hi Jeorg, Marco, Tord, ...

Before starting the big mSD6--mSD7 (8 threads) match, I decided to spend some time benchmarking some 4 thread configurations. The data below seems to suggest that mSD=6 or 7 and MNTpSP=4 is good. Not sure how to reconcile this with Jeorg's results.
I see mSD5 and MNTpSP=4 is very good also, indeed the second run of mSD=7 is not so good and mSD5 always takes less time to finish the search.

...yes....I bet my 5 cents on mSD5 and MNTpSP=4 :-)

Thanks Louis !

this for me is _the_ news of this sunday :D


Waiting for mSD7 vs mSD6.....
You'll need to wait a bit longer than expected. Maybe mSD7 needed a cigarette break. :shock:

Code: Select all

Started game 377 of 1000 
Game 377 ended: 1-0 {Black disconnects}
Stockfish 1.6.2-mSD6 64bit wins the game as white
Score of Stockfish 1.6.2-mSD6 64bit vs Stockfish 1.6.2-mSD7 64bit: 62 - 81 - 234
Finished match
I have no idea what happened.

I will start a 624 game match and add 61 - 81 - 234 to the results.

Here's the crash report. Looks like Thread 4 needed a smoke.

It crashed somewhere in qsearch() (at offset 1056 ?) It would be interesting on which instuction it crashed, if you have compiled with debug info (as is the default) perhaps it is possible that the debugger finds out what we have at +1056

Could you disassemble what we have at qsearch() +1056 ?

eventually with objdump -C -S

I don't know CrashReporter, perhaps it has some already built-in disassembling facilities.

Hi Marco,

I have no experience with this.

I used

Code: Select all

otool -tV ./stockfish-1.6.2-mSD7
and searched the assembly code to find

Code: Select all

Is this helpful?

Re: Stockfish-1.6.2 Benchmarks for 1 to 8 Threads

Post by Joerg Oster »

Hi,

thanks for doing all these Benchmarks, Louis.
This points me to MNTpSP=4 and MSD=5 or 6, but also MNTpSP=3 with MSD=5 and MNTpSP=5 is maybe worth a try.

Problem I have with these numbers is, you don't know exactly what is causing these differences.

Please have a look at my approach.
I took 8 opening positions(4 full moves from the starting position) and 8 endgames, and let them all calculate by SF 1.6.2 default with 1 Thread and with 4 Threads.
I calculated the scaling factor (nps_4T / nps_1T) and summed up the time to reach a certain depth.

Code: Select all

        MNTpSP=5	MSD=4		MNTpSP=5	MSD=4		MNTpSP=5	MSD=7

	Opening 7	1	232		   3,73	34		    3,19	70

	Endgame 7	1	60		    2,61	32		    2,95	47

You can find some pretty interesting details. :D
The default setting scales quite well in the opening, but not so good in endgames.
While the MSD=7 scales better in endgames, things get worse a bit in the opening. Especially the total time is much worse. That might explain why this setting seems to do a bit worse in my test match.

As you can see, I'm just at the beginning. I'd like to do some more testing with MNTpSP=5, 4 and even 3, before picking the 2 or 3 most promising settings for test matches.

So Marco, I have a question: can you provide a Stockfish version, where I can set this value (MNTpSP) down to 3? Maybe compiled by Jim Abblett again? :oops:
Unfortunately I have no experience in compiling source code.
In case you need my e-mail address I will pm it to you.

Any comments welcome, of course.

Joerg.

Some notes: the above numbers are all rounded.
