Not only that you mix two completely different persons, you also mix "to get a recommendation" with "to send something" which is also completely different. This is a quite bad style of opinion-making.

Re: w49921 net

Remember that they still use last official SF10 for testing They do not. They do.

Re: w49921 net

it is just one of hundreds of Lc0 nets. You'll find it here. http://lczero.org/networks/ One of the weakest net in T40. (Among full trained net). None of Leela user use it for analysis. As long as there is no official statement from the lc0 guys "THIS is our official net. Use THIS for rating lists"...

Nobody has anything to say to me at all?
All I can say is that the VICE videos on youtube were a great introduction to chess programming for me.
Keep on going!

Nothing seems to help here. No wonder, 'chessowl' is just infamous for spreading all kind of SF clones.
Indeed. I wonder what goes wrong with guys like him.

Re: Official Release of Ethereal 11.75, supporting MultiPV

It's probably better if you could set the perfect setup for Ethereal 11.75 under Linux/cutechess and then if it's running perfect, my "obviously bad setup" is causing the problem. Why should I? I'm not interested in testing Ethereal like you seem not interested in understanding what processor cores...

Re: Official Release of Ethereal 11.75, supporting MultiPV

Thank you very much for your suggestions not related to Ethereal. This is about Ethereal 11.75 and let's focus on the problem reported. I would appreciate if you could run Ethereal 11.75 on Linux with cutechess with concurrencies you desire and report if you have the same problem that I posted like...

Re: Pawn hash table, a little disappointment

Pawn hash (as well as position hash) are computed on the fly in apply or applyNull and computeHash will early return if already computed if (p.ph != 0ull) return p.ph; applyNull is xoring zobrist key for color and possible ep but this is bad design (this is because eval is returning score from stm ...

Re: Pawn hash table, a little disappointment

This line in your ::eval() seems strange: if (!getPawnEntry(*this, computePHash(p), pePtr)) { ... Seems that by calling computePHash(p) you recalculate the complete pawnhash from scratch? I checked that you already do "delta-hashing" in your movepiece so recalculating should not be necessary and may...

Re: Pawn hash table, a little disappointment

I'm using a total size for this table that is 1/16 of the TT. The table is well used, often there is a ratio of 10 read for only 1 write. But this is a slowdown of about 10% in knps ! I wonder how others engines behave ? There must be something wrong with your code. I would have a look but it seems...
