I remember to read, that neither SF nor Komodo has real NUMA support. According to Houdini document it has +50% boost to nodespeed with dual XEON and NUMA! Where did you get that number? People continue to be confused about 1) support for more than 64 logical processors in Windows, and 2) true NUMA...

Hopefully at some point we'll get the feature set that TCEC needs in mainline cutechess. Currently they're using this fork (which has some pretty impressive features) which is 534 commits behind mainline and it's almost pointless to try to debug it: https://github.com/jeremybernstein/cutechess If t...

Hello Darko, sometimes weird things happen in a time-limited match that cannot be reproduced by infinite analysis. During the game the hash table is fi...

For Houdini 6 updates I'm sending announcements without download links, so that the mail triggers less spam filters. So far it appears to be effective. Below the full text of the announcement. The Houdini 6.02 update is now available. The update provides support for Polyglot opening books . There is...

With 6-men Syzygy. I can confirm that even with 5-men Syzygy the solution is not easily found. Looking at the variations, I think it's because of this kind of 6-men position: [D]rn2R3/8/8/8/8/1PK5/8/6k1 w - - 0 6 Won for white, but you need a deep analysis to prove that without tablebases. The winni...
