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:

Code: Select all

variant = normal
book = 0
threads = 6
tt-shared = 1
tt-size = 25
bb-cache = 1
bb-size = 7
bb-preload = -1

or try,

Code: Select all

variant = normal
book = 0
threads = 6
tt-shared = 1
tt-size = 25
bb-cache = 1
bb-size = 6
bb-preload = 6

You should modify the number of threads, don't know how many cores your processor has.

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:

Code: Select all

boardsize = 10
engine = kr_hub.exe
protocol = hub

To display the hub messages, one should checkmark the Display GUIDE Messages in the EngineView settings

On can activate this dialog by right clicking in the EngineView Window and select Settings
The Engine view should look like below after start-up

KR_HUB.PNG (32.23 KiB) Viewed 13573 times

So far a game with Fixed Time seems possible.

Bert,
I found the problem.
The file (s) must be removed from the database folder.
It's ok to play.
Yves,

[BertTuyt]

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.

Bert

[Yves]

databases.
"database" to play.

Hi Bert,

For me, download it's in progress. I want to know if we can use the old endgame database or this it's different ?

Thank.
Sidiki.

[BertTuyt]

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

Thank Bert,
I downloaded all the files, i will try a dxp games.

Thank again.

And what does it mean tt-shared.

[BertTuyt]

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 (so tt-shared = 1).

Thank you for your answer Bert.

Damage 15.3 does not save batches properly pdn. I still have a question Bert - what can be the maximum number of options bb-cache and tt-size.

[BertTuyt]

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 GByte to get the total.
As many computers have 32 GByte or more, it was not my priority to find a better compression, or convert to the DBs made by Ed.

tt-size , i never tested this, but guess you could go to 31.

will check this...

DXP works correctly in the program - there are no problems. Option test tt-size and bb-cache. Below test of these two options. Bert whether large pages work correctly in the program.

variant = normal
book = 0
threads = 16
tt-shared = 1
tt-size = 30 or 29 - Please take a look at figure No.1
bb-cache = 5
bb-size = 7
bb-preload = 7

variant = normal
book = 0
threads = 16
tt-shared = 1
tt-size = 28 - Please take a look at figure No.2
bb-cache = 5
bb-size = 7
bb-preload = 7

variant = normal
book = 0
threads = 16
tt-shared = 1
tt-size = 27 - Please take a look at figure No.3
bb-cache = 5
bb-size = 7
bb-preload = 7


variant = normal
book = 0
threads = 16
tt-shared = 1
tt-size = 26 - Please take a look at figure No.4
bb-cache = 5
bb-size = 7
bb-preload = 7

variant = normal
book = 0
threads = 16
tt-shared = 1
tt-size = 25 - Please take a look at figure No.5
bb-cache = 5
bb-size = 7
bb-preload = 7

As for the tournament, I already know when it will take place. Information is not yet available to the public. Please believe me you can easily improve the format png. I even think you can make a book for the program.
