New engine: Caissa

[Graham Banks]

Try it in ChessGUI, which is what I use for my testing.

Where can I download it from?

I don't know, for me it looks like ChessGUI bug.

The options are properly reported:

Odd, because the previous versions have been fine under ChessGUI.

Version 1.9 is the first one without the Gaviota TB options. And it has a new option (show WDL).

Maybe that is the problem. Graham, have you installed v1.9 independently or by duplicating v1.8? What if you delete them then do a clean install of 1.9?

Sorry to bother if that is nonsense.

[Witek902]

I reverted all UCI options to version 1.8 so that "uci" command output is exactly the same as in version 1.8 and I'm still getting the same behavior (hang on Edit Engine Parameters leading to engine kill). I'm out of ideas...

[Gabor Szots]

When I start the engine these lines are displayed.

AdjustTokenPrivileges failed, error code: 1300
Caissa 1.9 (AVX2/BMI2) by Michal Witanowski
info string Loaded neural network: E:\Sakk\UCI-engines\Caissa/eval-13.pnn

What is that error? Does it matter?

BTW, can it be the new net causes the problem?

[Witek902]

The error means that the engine failed to enabled large pages (the exe needs some privileges set up in Windows settings), but it shouldn't be a problem. I think this error is printed since early releases and wasn't causing any issues.
The net shouldn't be a problem, because it loaded successfully and isn't used till "go" command is called.

[Graham Banks]

Could you compile an exe for me that uses 1024mb hash, 4 cores and uses the tablebase path E:\SyzygyTablebases by default?

[Witek902]

Could you compile an exe for me that uses 1024mb hash, 4 cores and uses the tablebase path E:\SyzygyTablebases by default?

It's not needed. You just set this exact command line options string in engine settings:

Code: Select all

"setoption name Hash value 1024" "setoption name Threads value 4" "setoption name SyzygyPath value E:\SyzygyTablebases" 

Basically all strings passed in command line in quotes are executed as an UCI command.

Thanks. I'll give it a try.

[Ray]

OK I can duplicate this in ChessGUI as well (although I haven't used that for years now)

Perhaps it does not like the "/" or the brackets in the UCI engine name, that is all I can suggest.

I was trying everything, nothing worked. So far I know it started to happen after I switched to using CMake to generate Visual Studio solution. Some project settings were different, but it still doesn't work when I made them the same. Very weird... I'll try building Caissa with GCC and see if it works

Eng07 (caissa-1.9-avx2-bmi2) <- AdjustTokenPrivileges failed, error code: 1300
Cancelling StartEngineTimerEvent() for caissa-1.9-avx2-bmi2 at 0000000189899531.

ChessGUI thinks the failure to allocate large pages is a critical error and then aborts ?

However, I still think that "/" in the UCI engine name is an issue. ChessGUI saves a file to disk, and that is not a valid character for a Windows file name.

Perhaps you could change that and generate a new exe for us to try ?

[Ray]

Solved it by manually editing the ChessGUI config files.

[Ray]

In the file ChsGUI_Eng.TXT

[Caissa 1.9 (AVX2-BMI2)]
MyName=Caissa 1.9 (AVX2-BMI2)
OriginalName=Caissa 1.9 (AVX2-BMI2)
EngineFile=C:\ChessEngines\Caissa 1.9\caissa-1.9-avx2-bmi2.exe
EngineAuthor=Michal Witanowski
CommandLine=
EngineCode=571763226312736 157288800 128 0 0 0 0 0 0 0 0 0
EngineInts=0 1 2 -1 0 0 0 0 0 0 0 0
EngineWords=0 0 0 0 0 0 0 0 0 0 0 0
EloValue=2400

In the config folder:
Make a plain text file called
Caissa 1.9 (AVX2-BMI2).uci

Put the following into it
option name EvalFile type string default eval-13.pnn
option name SyzygyPath type string default C:\Syzygy5
option name Hash type spin default 1024 min 1 max 32000
option name MultiPV type spin default 1 min 1 max 280
option name MoveOverhead type spin default 10 min 0 max 10000
option name Threads type spin default 4 min 1 max 1024
option name SyzygyProbeLimit type spin default 7 min 4 max 7
option name UCI_AnalyseMode type check default false
option name UCI_Chess960 type check default false
option name UCI_ShowWDL type check default false
option name UseSAN type check default false
option name ColorConsoleOutput type check default false

Then go edit engine and edit parameters and it should work.


However none of this would be necessary if the "/" was removed from the engine name. I'm 99.9% sure that that is the issue.

[Ray]

Shredder GUI is obviously coded to deal with this, when it creates the .eng file it silently substitutes the "/" automatically with an underscore.

Not only in FRC. I played a very short match between 1.12 and 1.13 but interrupted it after 12-0 in favour of 1.12. Can it be that the default of <empty> is not enough to play with the internal net?

Indeed setting EvalFile as "<empty>" causes no net to be used. Can you workaround it by forcing EvalFile option to an empty string? I'll try to prepare a fix soon
