Dev Builds » 20230223-1222

You are viewing an old NCM Stockfish dev build test. You may find the most recent dev build tests using Stockfish 15 as the baseline here.

Use this dev build

NCM plays each Stockfish dev build 20,000 times against Stockfish 7. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

Add support for ARM dot product instructions The sdot instruction computes (and accumulates) a signed dot product, which is quite handy for Stockfish's NNUE code. The instruction is optional for Armv8.2 and Armv8.3, and mandatory for Armv8.4 and above. The commit adds a new 'arm-dotprod' architecture with enabled dot product support. It also enables dot product support for the existing 'apple-silicon' architecture, which is at least Armv8.5. The following local speed test was performed on an Apple M1 with ARCH=apple-silicon. I had to remove CPU pinning from the benchmark script. However, the results were still consistent: Checking both binaries against themselves reported a speedup of +0.0000 and +0.0005, respectively. ``` Result of 100 runs ================== base (...ish.037ef3e1) = 1917997 +/- 7152 test (...fish.dotprod) = 2159682 +/- 9066 diff = +241684 +/- 2923 speedup = +0.1260 P(speedup > 0) = 1.0000 CPU: 10 x arm Hyperthreading: off ``` Fixes #4193 closes https://github.com/official-stockfish/Stockfish/pull/4400 No functional change
