Does Gaviota Not utilize Large Hash Tables?

Post by mhalstern »

I am running a G30 match with gaviota 64 bit as one of the engines. I told the Fritz 12 Gui to unify hash at 1024 meg however, the windows task manager shows Gaviota using around 114k.

Gaviota is a Winboard engine. It won't read UCI parameters.
Did you modify the file: gaviota.ini.txt
?

Dann is right. Check gaviota.ini.txt to modify the values. 1024 M should not be a problem.

I forgot about the ini file. I use wb2uci.exe and often forget which engines are not native winboard.

It appears that I am using the deafult entry of:

hashmem = 64 M

I'll change this for longer games.

What does the entry:

ref_table = 32 M mean?

Can and should I increase this as well?

That is a refutation table only. It contains the move but not the score. Increase it proportionally to the other.

At one point I thought it was a good idea (I could pack the info in much less memory) but I do not think so now.
