Something's not right there. Rybka should no way be down the bottom.

It is strange that Rybka not lose time on slow systems and make it into systems faster. I think that could happen with danasah me otherwise.

Swami, I believe that in your tournament now play some programs (mp) with 4 processors and others 1. Such the possibility of playing with ponder = on for all engines and 2 processors for those who can?

Hi Pedro,

I think Bright and ETChess was using more processors as well, other engines are just working well, except Rybka beta. How do i configure the engine to use 2, 4 processors etc?

I have seen the games also, I couldn't do anything other than just let it go. Engines don't use ponder on, I will see what happens in the rest of the division also.

I imagine that when an engine is MP, the number of processors must be configured in the ini file (rc, cfg, etc ) of the winboard engines and through the interface-gui in engines uci.

I do not know if any engine uses all processors and leaves no change. In the case of Toga there are different files for 1,2,4 and 8 CPUs

Thanks, I will check out for the Ini file before launching any tournament, however Rybka only comes with executable. Also How do i configure through Interface GUI in engine UCI?

In Arena --> Engine 1 --> Crtl + 1
Engine 2 --> Ctrl + 2

Or he could just right click>go to configuration..

Surprise super last by Rybka 1.0 beta.
I suppose Scorpio played without 5-piece egbbs.
With them, it should have scored much better.
Brights super first is also a surprise to me.

Best,

My guess is that bright was run with 4 cpu's, gaining ~120 elo over the single cpu version.

Swami, are your Rybka beta the patched one that shows right number of plies and nodes per second? The patched Rybka is known with its time losses, I think Rajlich said something about that

I think I downloaded it from superchessengine.com.

If you know of any reliable rybka beta, can you send me the link,I will download it again and run the tourney.

of course

This version of rybka also keeps forfeiting on time.

Another engine supports parallel search, I didnt even have a clue until I was configuring it today...

Hermann 2.3 Leiden

- option name NumberOfProcessors type spin default 1 min 1 max 8
# The number of processors used for parallel search.
# (More exact: The number of threads. It is possible to give a
# higher number than processor cores available.)
