Re: stockfish 10 vs. Mephisto III S Glasgow

What is MC69030 @20 Mhz ?? And what is your point. Mephisto III uses an 8 Bit cpu with 3.5 or 6 MHz. Not what you said at the beginning. You said at the top, "Mephisto III S was running on a 68000 with 12 Mhz and made 3-5 NPS. " I owned a Fidelity Mach II LA and the Spracklen program did 1000-2000 ...

Re: stockfish 10 vs. Mephisto III S Glasgow

My point was that higher nps is not needed for chess. Because there are ways to rely on knowledge instead of search. Why should I now increase nps ??? Of course Stockfish is the master of bean counting. I have no doubt that it will Win. But my point was that all those nps are irrelevant if you want...

Re: oldie but goody

I think that number is wrong. Sounds more like a sigma 6/7. IIRC, the sigma 9 had a .73 microsecond clock, which would translate to about 1.3MIPS. If every instruction referenced memory it could not run that fast, but it was pretty fast for the day. Today my Apple watch has more computing power. :)...

Re: oldie but goody

I don't know if I have ever released this, but I was looking through old files and ran across a REALLY old version of my chess program. WAY before it had the "Cray" in its name. This is version 6.9, dated 1977, which sounds right. Right after the WCCC that year, I decided to get rid of the highly s...

Re: My failed attempt to change TCEC NN clone rules

Nah, if they wanted that you'd have been asked about what was your favorite movie, and if you disliked some parts of it and stuff like that, some creative process, not force you to watch some movie and tell what it was about. The problem with a movie summary is that there's some expected standard, ...

Re: My failed attempt to change TCEC NN clone rules

So for the record, you agree that the lc0 cuDNN/CUDA backend is a very critical part to the strength of an NN-engine? I think I've been very clear and said *numerous times* that the cudann backend is a very important critical piece of code...But to be very clear, the sentiment I was relating above ...

Re: What the heck happens here?

I took the Sim tester which has some 8,000+ quiet positions with unclear best move and tested engines, including versions of Lc0 nets, all at 1 second / position and additionally SF_dev at much longer 10s/position and 30s/poisition. Also, for some check, one Lc0 at 0.2s/position. Hardware: 4 i7 cor...

Re: Linux flavors - opinions

... The other option is to compile the compiler itself from source. Good luck with that. Yes, you'll need it. After what seemed like weeks of preparation in my free time, I compiled an m68k cross-compiler using an 2.5GHZ AMD Phenom-II x4 830 which took about what seemed like 45 minutes. On an m68k,...
