Pedone memory consumption

[xr_a_y]

I'm running a tourney with many engines including Pedone.
I asked for 256Mb TT for every engine, all of them roughtly respect that but Pedone is currently using 1.5Gb.
Anyone already saw the same issue with Pedone ?

Maybe you have used a lot of threads or maybe you have used a larger trasnposition table and you have changed it without sending and ucinewgame. The transposition table is allocated once the engine receive an ucinewgame.
Are you using the tablebase or not? What are the commands that the gui sends to the engine and what gui are you using?

Thanks for your answer. I'm using cutechess, and ask for a 256Mb TT.

I think it is possible not all UCI GUIs send ucinewgame.

But the default hash size of an engine is probably not 1.5gb?

Cutechess cli or the gui? What OS are you using? Linux or Windows? I will have a look

I've found that under Cutechess Pedone refuses to run when you set concurrency greater than 4. Not a big issue, but strange.

I detected the issue under cutechess-gui for Windows.

I have solved the allocation problem and now it works also with concurrency. I have changed the development version so the fix will be available with the next release. Thank you for reporting me the problems.

Great. Thank you.
