Sure. We can use the word official for the Ethereal 12.75 SF-NNUE.nabildanial wrote: ↑Sun Oct 11, 2020 6:32 amI've deleted my compile since Andrew has released the official(?) one.
So I took a trick that I learned from some forum, and then saw put into practice in Cfish. Which is to look at the things defined when march=native is used, and then set the flags for vector maths basedon those. Its a brilliant trick. However, it assumes march=native. When you built for release, march=native was not set, and those flags were not updated. So you were using the slowest possible Ethereal compile. I imagine it was 2x or even 4x as slow.

I'm interested in that Ethereal without NNUE actually beats out Komodo and Houdini. Maybe an indicator that Ethereal's evaluation is very solid? I would not be surprised if it beats Komodo's. They've got more knowledge, but I'm confident mine is tuned better.Rebel wrote: ↑Sun Oct 11, 2020 12:31 am Ethereal 12.75 SF-NNUE +172

I have compiled one yesterday for people w/o popcount (but still SSE 4.1), because there is no suchnabildanial wrote: ↑Sun Oct 11, 2020 6:32 amI've deleted my compile since Andrew has released the official(?) one.
in the 'official' download at all. If someone is interested or needs it, just PM me.

Welp, that was a huge slowdown! Sorry I didn't test the compile, I assumed the "make release" was the appropriate compile flag for it, because you know, it says release on it haha.

Hi Andrew,
thanks for your Ethereal version.
Time for a new FCP Tourney, but the old tourney is not ready yet.
Later ...
Best

It looks like Andrew Grant might not be done with Ethereal yet:

Re: Final Release of Ethereal, V12.75
A few weeks ago, when everybody else was posting about Ethereal's final release version 12.75, Andrew Grant announced that he was writing his own neural network trainer, and then Halogen 7 came on the scene with a NNUE network that was trained on his trainer. So I thought, well, Andrew Grant probably doesn't want to get rid of his hard work on Ethereal's handcrafted evaluation function after trumpeting how much Ethereal's handcrafted evaluation function meant to him, so that is the reason why this was the final release of Ethereal, and his future would be working on Halogen with Kieren Pearson. But then earlier today he said that he wasn't working on Halogen; he was just testing his trainer with Halogen, which then brings up the question, then why did he write the trainer in the first place? Turns out in the dev version of Ethereal, he replaced whatever previous code he was using for endgames with a NNUE net, presumably trained using his trainer.MikeB wrote: ↑Thu Nov 12, 2020 9:49 pmOnce it gets in your blood, it's hard to get out.
