This fork just provides Android armv8 builds in the release section: https://github.com/Joachim26/FastChessForAndroid/releases/tag/v0.6.3-alpha These builds are compiled on Termux with gcc 10.3 or gcc 11.1.

fast-chess

fast-chess is a versatile command-line tool designed for running chess engine tournaments. Written primarily in C++17, it utilizes doctest as its testing framework.

With fast-chess, you can effortlessly orchestrate chess tournaments, configure time controls, and execute matches concurrently for optimal time efficiency. Extensively tested for high concurrency (supporting up to 250 threads) with short time controls (0.2+0.002s), it exhibits minimal timeout issues, with only 10 matches out of 20,000 experiencing timeouts.

What's New

• Enhanced Cutechess Output: The Cutechess output support has been refined to enhance compatibility with other tools. Simply switch the -output option to cutechess to enable it.
• Extended PGN Data: You can now track nodes, seldepth, and nps (nodes per second) in the PGN output. Refer to the -pgnout option for detailed information.
• Quick Match Option: We've introduced a -quick option for running quick matches between two engines with an EPD book. Specify -quick cmd=ENGINE1 cmd=ENGINE2 book=BOOK to swiftly initiate a match.

Current dev versions are available as artifacts from the CI.

Example usage

Here's an example of how to use fast-chess:

fast-chess.exe -engine cmd=Engine1.exe name=Engine1 -engine cmd=Engine2.exe
name=Engine2 -each tc=10+0.1 -rounds 200 -repeat -concurrency 4

Note that setting concurrency higher than your CPU core/thread count may not yield significant performance gains and could potentially have the opposite effect. Also it is highly encouraged to use an opening book.

Command line options

See man for a detailed description of all command line options.
