Re: Missing input in ponder
Looks like you need to examine what the input parser is doing. It is clear that the input is "go ponder wtime 9675 btime 9833 winc 1000 binc 1000" Why it only saw "go ponder"? Sure the engine reads "go ponder wtime 9675 btime 9833 winc 1000 binc 1000" but it gives no more input after that. In the l...

I have tried with only 1 thread.BeyondCritics wrote: ↑Thu Apr 15, 2021 12:06 pmYou have a bug that seems to break some basic abstractions, so it smells like UB.
Do you have several threads? If so, try to use only a single thread and see if the bug still happens.
I have used the sanitizers to check the engine but there aren't errors.

Missing input in ponder
I've tried my engine with cutechess-cli and ponder on and I've found a bug.

Android build with pgo
How do you build an android executable with pgo with the NDK? I've tried with these commands: $(NDK)/aarch64-linux-android21-clang ./main.c -s -static -pthread -O3 -flto -std=gnu11 -DNDEBUG -Wall -Wextra -lm -march=armv8-a -DNEON -fPIE -o ./Pedone_armv8 -fprofile-generate qemu-aarch64 ./Pedone_armv8...

Re: New release Pedone 3.0
Yes it's original, I've not used stockfish code, I've implemented only a similar idea with small differences to the net and with my own training code.
The net has been trained with 300M positions evaluated by Pedone with traditional evaluation at depth 14.

Re: Website engines
I have seen that the site has an old Pedone's version, to have always the latest one I suggest to add a link to Pedone's webpage https://sites.google.com/site/pedonechess

Re: New release Pedone 2.1
I don't know exactly why but this is the compilation command:
Maybe -fPIE could make the difference but I'm not an expert of arm environments.
Code: Select all
aarch64-linux-android21-clang ./main.c -s -static -pthread -O3 -flto -std=gnu11 -DNDEBUG -Wall -Wextra -lm -march=armv8-a -fPIE -o ./Pedone_armv8
