Fast-chess
fast-chess is a lightweight command-line tool to run engine vs engine matches in chess. it is a reinvention and further improvement upon cutechess-cli with focus on having less overhead, simpler compile process, and support for higher concurrency. It also offers several additional features such as pentanomial match statistics and the ability to pause and save tests. It has been extensively tested for high concurrency (supporting up to 250 threads) with short time controls (0.2+0.002s) where it exhibits minimal timeout issues, with only 10 matches out of 20,000 experiencing timeouts.
