Re: Stockfish One Thread Challenge
In CCC one thread SF (NNUE) beats 250 threads Ethereal! And plays equal to 250 threads Komodo or SF classic. Definitely doubling of cores don't give 70 ELO anymore :) . Looking at the first event, Dragon had 37 point out of 60 vs 1 thread SF. Now I don’t know if that’s a better or worse than expect...

Re: CCRL 40/15, 40/2 and FRC lists updated (6th March 2021)
... because testing GPU engines is a total pain in the arse. No concurrency, even if you had a machine with dozens of cores you can run only one match. Hi, Why is that? Do the GPU engines use all the available cores? I am thinking about getting a new PC with a GPU, that's what I am interested. I've...

Re: Zahak, a GoLang based chess engine
I am using a garbage collected language, I cannot really control when memory is freed when searching. So, the increase during search is probably normal. But why does it stay high even after search, I might have some memory leak, need to check, which is not exactly an easy task :( Ideally you would ...

Re: Zahak, a GoLang based chess engine
Nice work. I played 4 games against it with leela2200 (lc0 running a 16x2 T10 distilled net on cpu) on lichess. All tied up at 2 wins a piece.

Re: NNUE Research Project
Note that nets trained on non-stockfish data often have to have their scores multiplied by a factor in order to fall into a good range for alpha-beta. Values between 1.5 to 2.5 are common. I use a python script to adjust the final layer for this. The toga net used a 1.55 multiplier, if I recall. If...

Re: NNUE Research Project
I am looking for more engines that moved to NNUE. Anyone? The data so far is too less for conclusions. Toga III https://github.com/dkappe/TogaIII/releases Solly, ignore previous post, real numbers - SF12 -> RMS=72.63 | SIM=46.22 SF13 -> RMS=72.20 | SIM=45.65 Note that nets trained on non-stockfish ...

Re: NNUE Research Project
You have serious comprehension problems. Did you try at least to completely read Andreas first post? (We know your main expertise is a kind of childish trolling, but still...) Here is the part you cut off and 'replied' too. Ofc you have to look at remark #2 otherwise it makes no sense to reply at a...
