CCRL Discussion Board

Hi,

I just use the binaries that are available on github. Usually you can find exe binaries for at least 6 engines which are around testing elo +/- 50 points.

Using Process Explorer I can see that it uses only one thread while searching. I could not stop searching by issuing 'stop', it must be done some other way I guess. I’m slightly puzzled by this. When I run the engine from the command window on my PC, I can use ‘go depth 100’ or ‘go infinite’. When ...

Will that extra thread occupy a core constantly? I would not like it because it slows my machine down. Interface and search are running in separate threads, so two threads are used for running the engine. When running the search the usage of CPU goes to full use, but when the search stops, the usag...

A new version of Lambergar engine was released, fixing bug 1 and 3 mentioned in previous posts.

New version is available on
https://github.com/jabolcni/Lambergar/r ... tag/v0.4.1

Hi Gabor, first thanx for testing the new version of engine. 1. I have found the same results. If I hardcode initial value for hash to 256 MB I get twice the size compared to setting the initial value to 128 MB, so it seems there is something wrong how the resized hash table reserves the memory. I c...

I am announcing a new version of Lambergar. Latest version is now v0.4.0, release files for windows and linux are on https://github.com/jabolcni/Lambergar/r ... tag/v0.4.0

New version should be around 2650 ELO Blitz rating.

Thanks for letting me know that. I am already developing a new stronger version with improved time controls and history statistic. While I certainly plan to release this improved version, it won't be in the immediate future, I don’t think I will manage it this year. I will obviously need to look int...

I had to study a little bit for what kind of x86-64 arhitectures I need to release the engine. This latest release should solve the problem. Release x86-64-v3 should work on most moder PCs, I tested it on skylake, which is not the latest and greatest. Release x86-64-v4 does not work on skylake, but ...

I fixed the issue with uci commands (I hope). I added two builds for Intel arhitectures. Latest builds are on https://github.com/jabolcni/Lambergar/r ... ag/v0.3.1b

I put a space after each command and this is how it looks: uci isready quit id name Lambergar v0.3 id author Janez Podobnik option name Hash type spin default 128 min 1 max 4096 uciok It is strange that the outputted lines appear only after 'quit'. Anyway, the requirement to add a space after each ...

The computer where I compiled the engine is quite new, so it might be compiled for new arhitecture. I compiled engine for hashwell arhitecture and uploaded it on github as lambergar-v0.3.1-x86_64-windows-general.exe. This one might be more "general".

Try to put "space" behind each command, that may help. Default value for hash table is set to 128 mb, 534 mb seems strange. Hash entry is 128 bits in size, so if I would miss the calculation of hash size it would be way of. I installed arena and in my arena gui it says that the usage is 18...

Hi Gabor,

indeed I am from Slovenia, my name is Janez Podobnik and there is no need to remain anonymous.

Thank you for adding my engine on the list for testing.

Regards,
Janez

Hello all, I would like to propose a new chess engine called Lambergar for testing on CCRL board. I have been developing it now for a few months. Lambergar is written in zig programming language. Current version is 0.3.1 and is a first public release. Homepage and source is on Github: https://github...
