I see, seeing how 88 is half of 176 it seems as if they did that so that komodo would get to use more processing power than if it was just 128 threads with hyperthreading. >For SF, maybe it's better to not use all the threads due to NNUE using more CPU instruction and CPU power, so leaving 4/176 free improves stability ? They are afraid that stockfish will fry the tcec computer :P They find it unfair that stockfish will use more electricity so they decided to reduce the number of threads :P Where in tcec can I see the threads used? I still haven't found the spot. |
| 31455 | Mrert 2020-09-25 17:39:34 | @sad13: K is supposed to support up to 128 cores. 88 is the number of physical threads. Except if they have a code to disable hyperthreading for K (using 88 physical cores instead of 176 hyperthreads) on the fly while running, I don't see any reason for that setting.
For SF, maybe it's better to not use all the threads due to NNUE using more CPU instruction and CPU power, so leaving 4/176 free improves stability ? All of this is just speculation |
| 31454 | sad13 2020-09-25 14:04:47 | >Fire and Ethereal have 176, SF 172 and K 88 threads
That could explain komodo's poor performance.. I guess komodo doesn't yet support more than 88 threads? Why stockfish only 172 though? Where in tcec can I see the threads used? |

| 31452 | hww 2020-09-25 09:14:52 | the misguided idea of embedding is not suited to frequent downloading of abrok binaries as you will wastefully download the same net again and again multiple times
repeatedly wasting storage and wasting bandwidth the links of the nnue nets have been removed from the download page because of embedding roman can fix this 31034 @roman set up poll so he know what we the users want result has to be clear enough that he remove embedding from his exes here please restore sanity to stockfish Vote default net NOT embedded https://www.strawpoll.me/20882042 |
| 31451 | Mrert 2020-09-25 07:05:29 | Wait, what the hell are those thread settings ?
Fire and Ethereal have 176, SF 172 and K 88 threads |
| 31450 | Mrert 2020-09-25 06:55:01 | already 2.3... looks like the opening was busted |
| 31449 | Mrert 2020-09-25 06:46:48 | SF-K underway, let's see if SF's loss was due to a busted opening |
| 31448 | Lalit Mohan Bankoti 2020-09-24 21:44:14 | WCN,But stockfish team have to work hard on Sicilian all variation due to lost against komodo.otherwise stockfish was unbeatable in tcec season 19 premier division. |

| 31442 | Mrert 2020-09-23 19:28:43 | yes x64 uses sse2 |
| 31441 | abroke-WATCH! 2020-09-23 19:12:54 | I just worked it out! :)
hww and sad13 are the same person doing multiple Posts! :( How can we STOP! this nonsense!!! ? |
| 31440 | Franky 2020-09-23 14:51:49 | Thanks for your efforts Mrert, always answering everybody's questions... |
| 31439 | GregC 2020-09-23 09:57:16 | Many thanks! :)
Do you happen to know what level of SIMD the x64 code uses? I think it's SSE2, which has been around since the dinosaurs. |
| 31438 | Mrert 2020-09-23 06:41:24 | it would be interesting to know how much faster the most modern instruction set are (AVX512, vnni256, vnni512). But you need a very recent high end intel...
Actually x64 is not that slow compared to the first NNUE compiles where it was abysmal, several times slower than bmi2. They did a pretty good optimization job |
| 31437 | Mrert 2020-09-23 06:37:53 | Great idea actually.
Running SF12 with "bench 64 1 14 default depth NNUE" (1 thread, depth 14, use NNUE) 3 times per compile: x64: 654 kN/s ssse3: 806 kN/s -> 23% faster modern: 816 kN/s -> 25% faster AVX2: 940 kN/s -> 44% faster bmi2: 989 kN/s -> 51% faster Interesting. modern doesn't bring much more than ssse3, while leaps between other compiles are clear. |
