Dev Builds » 20120930-0819

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 node limited search Handle also the SMP case. This has been quite tricky, not trivial to enforce the node limit in SMP case becuase with "helpful master" concept we can have recursive split points and we cannot lock them all at once so there is the risk of counting the same nodes more than once. Anyhow this patch should be race free and counted nodes are correct. No functional change.
