After turning on the "Large pages" option, the maximum speed was 53.8 Mn/s. How to enable the option " Large pages " https://www.chironchess.com/support/lar ... ws-7vista/

Krzyzstof, thats fine.

Of course it doesn't speed up the engine but engines that use "large pages" can use a larger hash-table without the usual slowdown when the table gets larger than let's say 1.0 GB.

With the long time-control games you are running and on 16 threads it is better to give my engine a 4.0 GB hash-table by changing the tt_size to 32 in ares.ini.

The test match is still running, after 77 games the score is: 2 wins, 1 losses, 74 draws, KR has 1 point advantage now. Certainly better than the "broken" version, at this stage it already had lost 8 games or so.

Krzysztof,

I've uploaded the corrected version to Dropbox, it also contains a different network:

https://www.dropbox.com/s/cdvxn4ygbbhl5 ... b.rar?dl=0

For the time being this is as good as it gets, probably I have better networks but testing which one is the best takes too much of my time.

Thank you Joost. I can test both versions (but I don't know if I can or if you will allow it). I changed the entry in the "setting" tab - still left the option "Ponder" - On - https://www.uwccpi2021.draughtsprograms ... tings.html

Joost,

i thought about this question, and what happens if i set "threads" to 32.The tournament is played on separate computers.

Then you'll make use of SMT, nothing will happen the engine supports up to 64 threads. Maybe the N/s will go up but I doubt that it will play stronger, possibly even weaker.

About pondering, I still have to add that, the coming 2 weeks I'm on vacation but I will try to add it the last week of August.

The 1.40b version that I put on Dropbox clearly has a problem, my guess is an overflow in the 8bit SIMD code, I have to look at that. If you want to test it be my guest, but I don't think it is very useful.

The past 4 months I tried several different networks, smaller, larger and different architecture. The problem is that I more or less lost track about which one performs best, so I doubt that the network you have over there is the best. Today I will try to find a better one and upload it to Dropbox, then you only have to replace weights.bin with the new one.

Maybe I should give different networks a different name, this would make it more easy to distinguish between one another.

NNUE for international draughts is still in it's infancy, it will get better over time.

Krzysztof,

It seems yesterday I messed up and gave you a bad NNUE weight file. I had to copy the weights from one machine to another via my network and mistakenly created a link to the wrong folder without noticing this. Maybe the engine was not bad after all.

Can you please delete the weight file you already have and replace it with the one at this link:

https://www.dropbox.com/s/lkkxdvx10dfw7 ... s.rar?dl=0

I've been testing these this morning vs Kingsrow 1.63 (16 cores, 90 moves in 1 minute, KR uses 6P EGDB), and the match came out at -11 Elo. This is more or less what I expected. I have attached the games.

Krzysztof,

The NNUE version of my program is only 7 months old, there is still room for improvement. The last ten days of this month I have time to work on it, I will notify you when I find some improvements.

Some tournament information.

Thanks to Jan-Jaap van Horssen for the opportunity to use the program in the tournament. Not all programs have been updated yet. This will happen at a later date. I would also like to thank the other programmers for participating in the tournament.
