TheKing 3.50 engine ponders during opponents thinking time !

[Sedat Canbaz]

Hello there,

Does abnybody noticed it,where TheKing 3.50 engine ponders during opponents thinking time by using 1 thread(CPU)
Normally the GUI's option is set to ponder off,but anyway it still continues to ponder,if its a dual machine thats means 50%,if its a Quad machine,then TheKing uses 25%...

This problem appears under all GUIs(Fritz,Arena,Shredder,Winboard)


And here is my Fritz configuration:

[ENGINE]
Name=The King 3.50 x64 t4
Author=Johan de Koning
Filename=Wb2Uci.exe

[OPTIONS]
Program=TheKing350x64.exe /t4
InitString=cm_parm default\ncm_parm opk=228561\ncm_parm tts=134217728 opp=100 opn=100 opb=100 opr=100 opq=100 myp=100 myn=100 myb=100 myr=100 myq=100 mycc=100 mymob=100 myks=100 mypp=100 mypw=100 opcc=100 opmob=100 opks=100 oppp=100 oppw=100 cfd=0 sop=100 avd=0 rnd=0 sel=14 md=99\n

Hi Sedat,
I remember - there is no solution.
So I used a dual to test single-single engines with ponder off
and I used my quad to test TheKing with 2CPUs
to be sure to have the same conditions.
In eng-eng matches TheKing does not ponder but it is using the free CPU.

Hello Werner !

In other words...currently i set TheKing's option to t1 against mp engines.However if we set the option to t2, it again uses 1 thread thats means its will be disadvantage for the rest of the mp engines

Hi,
if you set t=2 and play eng-eng against another 2CPU opponent on a quad all is ok.

Hi,
A golden hint from the good doctor :
Yes,The King 3.50 always reserves 1 cpu even with ponder off,but....as the author of the engine stated once,it does not actualy ponder and if the opponent of The King 3.50 needs the cpu,it will get a full advantage of it
Sedat,try to make the following:
Match the engine with ponder off and t2 against another MP engine and notice the Kn/s of the opponent,then check with t1....there will be no drop in the performance and you'll see that the statement of the author is correct....
The King 3.50 expert regards,
Dr.D

P.S.IIRC,Ray Banks can confirm my statement

Thanks for the medicine my dear doctor

Yes...i think i will set it to t2 against mp engines,at least it will be more near to equal conditions

About t4 i can use it only against single processor engines

You welcome Sedat

Yes ...Wael,you are rght,i have tested TheKing 3.50 x64 using 1 thread and 4 threads against Rybka 3 and noticed that the kns of of the Rybka engine were same in both cases.

So i will continue testing The King using 4 threads against mp engines

...be careful with that medicine

I have watched some games and after 10 moves or so TheKing suddenly does not give that thread free...

In my testings,TheKing 3.50 x64 t4 even up 10 moves uses 1 thread during opponents thinking time and still not sure that will affect the performance of the mp engines if i set the option to t4 ?!
