Re: Damage 15.3

Krzysztof, thanks. Were these results with your ThreadRipper, as the timing difference for PERFT is smaller then I would expect based upon the clock frequency (3.4 GHZ versus 4.3 GHZ). It could be that the test run in turbo-boost so the actual frequency was somewhat higher. Anyway if it was the Thre...

Re: Damage 15.3

Krzysztof, I want to get an idea of your Threadripper speed, and if the PEXT is the main reason for the lower nodes/second. Could you type in the Damage engine the command #perft 11, to start a perft. You should get next output. As perft (movegenerator) does not use PEXT it might give some clues abo...

Re: Damage 15.3

The program will most likely crash, or play non-sense moves. I left the file by accident. My first priority was to share something with the community which worked (so GUI and Engine). Which seems to be the case. Next priority is to test the improvements i have on my list, so strength will get closer...

Re: Damage 15.3

Krzystof, thanks. I meant to do these simulations with the initial position (so white to move). But I could at least reproduce the 1-core result. See below screenshot fro the Damage GUI. All numbers are the same, only (huge) difference is the search speed. In your case 6.99 MN/s, in my case 17.86 MN...

Re: Damage 15.3

Krzysztof, I uploaded a new version (damageengine153.exe), available in the download link (date should be today 5:06PM) could you check how this behaves? I removed the large pages support as this did not work in my case. As I did not optimize the engine for AMD, is still use the PEXT so speed might ...

Re: Damage 15.3

I know that pdn files as produced by the Damage GUI are still not ok. But again I wanted to finalize an engine for your tournament, and hereafter I can work on some bugs in the GUI. bb-cache=5 is the maximum, as the total database size is 16.7 GByte, and you should multiple the bb-cache size with 4 ...

Re: Damage 15.3

tt-shared determines if all threads use (share) the same (tt-shared = 1) hash table or not (tt-shared = 0). I use this option when I generate many games for the learning algorithm, and every thread deals with one game, and has a separate hash-table. In normal game play tt-shared should be set to 1 (...

Re: Damage 15.3

Sidiki, the databases (.cprx) are from 2015, only the DB64Header.cprx (17-8-2019) has a new format.

Re: Programmer poll: TCEC-like competition for draughts engines

JJ, hope all have hub soon, it would motivate me to really work on the Tournament Manager in the Damage GUI.
See screenshot, which is still work in progress.

Re: Damage 15.3

Yves, I don't understand your post.

The file (s) must be removed from the database folder.

Maybe you can provide a screenshot for clarification.

Re: Damage 15.3

Although I did not test it in detail, one can also use the Damage GUI for the kr_hub engine. One should add all the kr_hub files to the engine directory, and change the damage2020.ini into: boardsize = 10 engine = kr_hub.exe protocol = hub To display the hub messages, one should checkmark the Displa...

Re: Damage 15.3

Yves, then you might have an issue with the preload, as you do not have sufficient memory. Can you try to change the damage.ini file (directory Engines) into: variant = normal book = 0 threads = 6 tt-shared = 1 tt-size = 25 bb-cache = 1 bb-size = 7 bb-preload = -1 or try, variant = normal book = 0 t...

Re: Damage 15.3

Yves, thanks for your email.
For my understanding, you see this message during initial startup?
How much memory does your system have?

Re: Damage 15.3

Herewith some background of the download. Included is the Damage GUI, Engine, and the 7p DB (around 16.9 GB). Also all should work out of the box, just start Damage2020. It could be that additional Microsoft installs are needed, but we will find out soon. The Damage GUI is basically a bug factory :)...
