Re: Is in this world really no compile of Sf-NNUE for arm-8?

I managed to make android version (from nodechip source) using standalone toolchain, and i want to ask you something. Why your compilation is 1.446 KB while mine is 723 KB, also your is faster about 200 nps, did you make it on Linux PC? Or there is another way for engines compiling with NDK's clang...

Re: Stockfish NN release (NNUE)

I think this happens because your script is not compiling all required files. You need to compile all files corresponding to the SRCS variable in the Makefile. Yes Peter you are right, i overlooked some files, tnx! That file does not exist. I think it should be: D:\Downloads\0\toolchains\llvm\prebu...

Re: Stockfish NN release (NNUE)

For recent NDK versions you no longer need to create a standalone toolchain. You can run the compiler directly from the bin directory created when unpacking the NDK zip file, e.g. something like d:\android-ndk-r20b\toolchains\llvm\prebuilt\windows_something\bin. Ok Peter, so what now? https://i112....

Re: Stockfish NN release (NNUE)

I'm using NDK's toolchain with Clang (not GCC) for android engines, on my PC (Windows 7 x64). Since android's Clang doesn't have a shell (the shell appears only once, when clang generate engines). I'm using a batch file with follow commands (eg for normal Stockfish arm7). echo Generating 32 bit eng...

Re: Is in this world really no compile of Sf-NNUE for arm-8?

Here is a version for 64-bit Android that should work at least for Android 7 and later: https://www.dropbox.com/s/zz6cgi5kxbupdv6/sf_nnue_armv8_api24?dl=1 I needed a small patch to enable ARM NEON vector instructions, which on my Galaxy S10 phone makes the engine about 2.75x faster than without vec...

Re: Stockfish NN release (NNUE)

start the engine in terminal and type "ucinewgame" - you should see a message confirming the nnfile was loaded. If you do not, you may have that missed that the build command was changed for building NN e.g., make ARCH=armv7 build COMP=gcc would become make -ARCH=armv7 nnue COMP=gcc Hi Mike, thanks...

Re: Stockfish NN release (NNUE)

Hello guys! I have a couple questions regarding android engines. I've made engines armv7 and armv8 (from nodchip's source code), and when i start the engine in the Droidfish, engine's behavior is identical to normal SF (although nps are much lower). Also in Droidfish/uci directory i've created a fol...
