Re: What happens with my hyperthreading?

60% speedup from hyperthreading using SF NNUE at longer TC, pretty crazy. What's that? 4 physical cores, 8 logical Games Completed = 100 of 100 (Avg game length = 60.676 sec) Settings = Gauntlet/128MB/15000ms+250ms/M 700cp for 3 moves, D 120 moves/EPD:C:\LittleBlitzer\2moves_80_100.epd(1749) Time = ...

What happens with my hyperthreading?

With mine i7 4790 4 physical cores, 8 logical, I seem to get a tremendous boost from hyperthreading with both SF_dev and SF NNUE, especially SF NNUE. Did something happened with Intel hyperthreading on Windows 10 and I am unaware of? First, SF_dev in ultra-fast games 8 threads vs 4 threads with Litt...

Re: Vintage .... Rating List Winboard from June 1999 (16:42)

Current SSDF rating list looks interesting, and I think they use something similar to ELOStat. https://ssdf.bosjo.net/list.htm They are veterans of 2000-2700 Elo ratings of top engines compared to humans, and the lower part of the table should be fairly accurate with respect to human ratings. Here ...

Re: Vintage .... Rating List Winboard from June 1999 (16:42)

Hi Kai, the current SSDF is very interesting. I think 125 - 200 Elo to high for chess engines and 25 Elo to high for the chess computers (if I compare with my own results). Spectrum isn't easy to explain because it have many reasons I think. SSDF = More higher the ranking, more realistic for myself...

Re: Vintage .... Rating List Winboard from June 1999 (16:42)

OK, so you are saying that CCRL 2600 (roughly CEGT 2400) = FIDE 2600, and that CCRL 2300 (roughly CEGT 2100) = FIDE 2100. So this means that the engine rating lists substantially UNDERESTIMATE rating differences in human terms!! Both you and I have said the exact opposite many times, I think you es...

Re: Vintage .... Rating List Winboard from June 1999 (16:42)

Hi Larry, and same situation we have in Winboard times. All the winboard engines are not very strong in endgames on AMD K6-2 or AMD K6-3. First program really strong in endgames are Shredder! Stefan Meyer-Kahlen developed Shredder 3.0 for Winboard too (a secret mission). I tested WB Shredder 3 vs. ...
