Date: Tue Nov 27 08:53:14 2018 +0100 Timestamp: 1543305194 Simplify casting extension On November 16th, before the removal of the depth condition, I tried revising castling extensions to only handle castling moves, rather than moves that change castling rights generally. It appeared to be a slight Elo gain at STC but insufficient to pass [0, 4] (+0.5 Elo), but what I overlooked was that it made pos.can_castle(us) irrelevant and should have been a simplification. Recent discussion with @Chess13234 and Michael Chaly (@Vizvezdenec) inspired me to take a second look, and the simplification continues to pass when rebased on the current master. This replaces two conditions with one, because type_of(move) == CASTLING implies pos.can_castle(Us), allowing us to remove the latter condition.

Date: Tue Nov 27 08:39:23 2018 +0100 Timestamp: 1543304363 Turn on MADV_RANDOM for Syzygy mmaps (on Unix-like builds) When running on a cloud VM (n1-highcpu-96) with several NVMe SSDs and some non-SSDs for tablebases, I noticed that the average SSD request size was more than 256 kB. This doesn't make a lot of sense for Syzygy tablebases, which have a block size of 32 bytes and very low locality. Seemingly, the tablebase access patterns during probing make the OS, at least Linux, think that readahead is advantageous; normally, it gives up doing readahead if there are too many misses, but it doesn't, perhaps due to the fairly high overall hit rates. (It seems the kernel cannot distinguish between reading a block that was paged in because the userspace wanted it explicitly, and one that was read as part of readahead.) Setting MADV_RANDOM effectively turns off readahead, which causes the request size to drop to 4 kB. In the aforemented cloud VM test, this roughly tripled the amount of I/O requests that were able to go through, while reducing the total traffic from 2.8 GB/sec to 56 MB/sec (moving the bottleneck to the non-SSDs; it seems the SSDs could have sustained many more requests).

Date: Tue Nov 20 08:00:19 2018 +0100 Timestamp: 1542697219 Force time check on TB probe in search. Because of aggressive time management and optimistic assumptions about move overhead, it's still very easy to get Stockfish to forfeit on time when we hit an endgame and have Syzygy EGTB on a spinning drive. The latency from serving a few thousand EGTB probes (~10ms each), of which there can currently be up to 4000 outstanding before a time check, will easily overwhelm the default Move Overhead of 30ms. This problem was first raised by Gian-Carlo Pascutto and some solutions and improvements were discussed in the following pull requests: https://github.com/official-stockfish/Stockfish/pull/1471 https://github.com/official-stockfish/Stockfish/pull/1623 https://github.com/official-stockfish/Stockfish/pull/1783 This patch is a minimal change proposed by Marco Costalba to lower the impact of the bug. We now force a check of the clock right after each tablebase read. No functional change. see source |

We wrote this patch specifically to address a problem that arose while running Stockfish with 7-piece tablebases as a kibitzer at TCEC for extended periods of time across multiple games. It was noted that after some time, the NPS of the kibitzing Stockfish (which is usually 3x faster than the Stockfish actually competing) would drop precipitously, eventually falling to preposterously low numbers until restarted. Their eval bot basically inputs FEN, go infinite, stop and loop, it probably didn't do ucinewgame either. As time goes it gradually slowed down and OS starts to use swap, this is not reasonable since the engine only uses 16GB hash and the machine has 1TB physical RAM and does nothing else.
