Re: Jumbo 0.6.96 64-bit Gauntlet for CCRL 40/40

So Sven if you want me to add one more test I can since this is running on a 6 core processor. Just let me know. Sounds interesting, thanks for your tests! If you actually have some spare resources left for another test then I would be interested in something that would allow to compare Jumbo 0.6.9...

Re: Jumbo 0.6.96 64-bit Gauntlet for CCRL 40/40

I don't think you can expect LTC results mirror, or even closely follow, those obtained in hyper-bullet tests, Sven. Sometimes they do, other times they don't. Of course I agree. If you're looking for a confirmation of your results our blitz list would be a better place to look. Currently v0.6.96 i...

Re: Jumbo 0.6.96 64-bit Gauntlet for CCRL 40/40

Thanks for the tests! When comparing current CCRL Jumbo ratings to my own test results for versions 0.6.* I see some significant differences for 0.6.66 and 0.6.96 which I do not understand. For older Jumbo versions both CCRL and own test ratings are matching pretty well. Here are my relative ratings...

Re: New Engine: Allie (NN)

When AllieStein played on Div 4 it was not performing as good using the MCTS and without EGTB, but on the second part it switched to A/B search and it won all of its games except one single lost. You mean the engine was changed during the running division? I don't think so, maybe between Div 4's st...

Re: 20 New NN Engines has been reported to the TCEC

The Baron does not use neural nets (yet). The version registered to TCEC is a NUMA aware compile of 3.44 Richard. Is NUMA awareness currently required at TCEC? Condition for required: Running windows with 64+ threads. Without NUMA awareness you can't get optimal thread to CPU distribution. Conditio...

Required not. Recommended yes, as it is a dual-socket machine.
Ok. Is there a common estimate of the slowdown for a non-NUMA-aware engine on such a machine?

No nothing. It only counts passed pawns, weak pawns, space and king position.
[Only checks if weak pawn is blocked by bishop]
Then only fast and deep search can avoid running into that problem in unlike bishop endgames.

Re: Can't beat fairy-max

Mostly endgame problems in this game:
61...Bg4? changes from forced win to draw (many other moves were winning)
72.Kg5? blunders away the draw but 72...Bf1? misses the forced win again (better Kc4 or Ke4)

Does SchaakMachine handle unlike bishops in its endgame evaluation?

Re: Why is the 64bit version normally faster than the 32 bit?

This is usually true for bitboard engines where processing of 64-bit numbers is being used heavily. A 32-bit version needs to emulate all operations on 64-bit numbers by twiddling with two 32-bit words instead of one 64-bit word.
