Hi!

Here is the situation:
I have Core 2 Duo 3GHZ, Windows 7 Ultimate, 2GB RAM
I open Fritz 12 GUI, choose a particular engine, analyse a game using Blunder Check.

Observation:
While the above operation is ongoing, I check Windows Task Manager and see processes which are running, and note that:

If the particular engine is Rybka 3, there shows two (2) Rybka 3 engines in process.
If the particular engine is Fritz or Igorrit or Firebird 1.1 only one is in process.

I checked the parameters of Igorrit and Firebird and selected 2 CPU, but still one process shows for each engine.

Is the above normal?

I finished a 7-game match between Rybka 3 x64\Core 2Duo 2.2 GHZ versus Igorrit v9 x64\SU7300 and the results favor Rybka 4/7. Time control is 10 minutes/game. I know the SU7300 is weaker but I was looking for an excuse, hence I entered this post.

Also, 7 games is not enough I think. But the way I did was tedious, manually entering the moves on two computers. I have my network configured as Workgroup, as I have not learned how to connect PCs in LAN as Server/Workstation, which is how Fritz auto232 would accept only. Or is there some workaround to this?

Thanks

Pogi,

Regarding the number of processes yes this is normal that Rybka shows several processes running and other engines show only one. The important thing to check is the % CPU being used by the process. If you have a 2 core PC then if you run a single processor engine CPU in task manager will be 50% but if the engine is using 2 cores then the process will show 100% (or almost as the GUI uses some). Similarly on a quad processor if the engine is using all 4 it will show 100% CPU in task Manager, whereas Rybka is different it will show 4 x 25%.

Goldminer thanks for explaining.

Meanwhile I continued with testing Firebird 1.2x64 which I let run on the slower SU7300 versus Rybka 3x64 running on Core 2 Duo 3.00. Ten minutes per game. Rybka using Fritz12.ctg and Firebird on Rybka.ctg.

3 games were finished last night, the first two games drawn. The 3rd game reached the endgame with equality and for a while I thought there will be another draw. Three games drawn by Firebird using weaker resources is noteworthy in itself. Although that was not the case because Rybka lost.

I really must start to get things going on auto232 so that I can have more data.

Again thanks a lot!
