Hi all-

I got a nice speed increase (~8-10%) for these aio (all-in-one) builds:

Looks great, Norman, thanks.
Seems to work in nnue-gui 1.4 too, pity I don't know, if directory eval was empty, when I tried previous leraning- binaries, now it is, which aio- binary doesn't expect to be so now as for gensfen- command.
Trying to copy an already existing net into eval?

What does UseEvalHash do? Seems it can be chosen together with EvalNNUE?

Norm, a lot of us, less computer/programming savvy, owe you a big thanks for all the work you did over the years: for Robbo, Fire, and now the SF NN. I regret you did not persevere with the GUI project -- I am sure it would be an excellent piece of software too. Your focus on clarity, ease of use, comfort/options is almost unique here.

Hi Peter-

The EavlHash is an extra hash for nnue evaluations...
Some users on nnue discord noted: 'I am observing a 7% speed gain when disabling EVAL_HASH on Stockfish bench (without any network loaded, which might distort the results).'

but it's possible it's beneficial during training...?
Therefore I have included a UCI Option to enable/disable it.

That's kind of you
Thanks Boban

Hi Siddhartha,
I have no intention of integrating NNUE into Fire...
perhaps others will take this step.

I'm enjoying working on Stockfish NNUE at this point.

Is this working with the CB GUI? I seem to get an exception error when I try and load the engine.

Well there's a workaround that seems to work...it seems CB/Fritz may have an issue with the default UCI option EvalFile path as it stands (which has recently changed in the master)
./eval/nn.bin

Try this:
change that to
nn.bin
and make sure that file is in the same directory as the binary

I'll spend some time trying to see why that is, and fix it when I have some time

For me popcnt- compile works in cb12 and in Fritz 14.
