First I must admit Arena 3.0 is very good now. After 2 months use I have't seen a single crash or time loss! It only takes a long time to set
appearance as You like it. But when running tournament I noticed, that some engines don't use allocated hash memory. I have set in UCI settings common hash 128M, but Stockfish don't use so much

Re: Arena 3.0 and hash table problem in tournaments?
Seems to be totally random, if hash size (128 MB) sent to engine or if it's using default value (32MB)...

Re: Arena 3.0 and hash table problem in tournaments?
I have noticed the same thing. Inconsistent use of pre-set hash value (in UCI tab in Arena 3.0) by Stockfish.Jouni wrote:Seems to be totally random, if hash size (128 MB) sent to engine or if it's using default value (32MB)...

I'm not sure if it is true for other engines or not as I use Stockfish almost exclusively so the bulk of my time is spent with that engine.

Re: Arena 3.0 and hash table problem in tournaments?
I started 3 engine tournament. Observation: in first 3. games everything
correct after that only default hash for all engines e.g. Sf, Critter and spark. May be i must set restart arena after every 3. game
