Why only 8Mb hash?

I gave your previous version 64Mb (instead of the default of 2) and it scored about 100 elo more.

Actually I've changed the default from 2 mb to 8, but you can always `setoption name hash value ..` to make it use more/less. Isn't this how the testers usually set it?

I appreciate the testing you do for Bit-Genie!

Most people test out of the box, thus in your case 8Mb, which is fine for bullet testing, for longer time controls (such as for rating lists or tournaments) it is not. If there is no particular objection I would make the default hash table size at least 64Mb. A hash table of 8Mb is full within a second.

I started the test for the GRL, I have set the hash table to 64Mb.

So I climb the ranking list by switching to more default hash and threads? Or enabling opening book by default?
Testers not setting at least these basic options to common values disqualify themself imo.

Engines testing at OpenBench are requested to use a small default hash because some workers are quite low at RAM compared to number of cores and bench signature run is using the default hash.

The context of my point was a) related to the hash table size only and b) to a relative new engine author. A default setting of 8Mb for the hash table isn't a great idea for a release version.

I'm sure hoping CCRL is setting the TT's to 256 MB (if the engine permits it)... they say so on the website.

One reason to set a small TT by default is if the engine needs to run on a small device, like an older raspberry, or even a microcontroller. Or you'd need to do conditional compilation to set different sizes for different build targets.

Of course.

Stockfish default is 16 mb, and I don't see anyone complaining
