A hybrid Stockfish NNUE?
I wonder if it would be possible to make a hybrid version of Stockfish NNUE, with the search running on CPU and the evaluation on GPU. If so, would it be possible to use larger networks?

You can do that with Eman Chimera… No need to make a hybrid on SF NNUE

Instead us with normal CPU who not use graphic cards have had enough of such engines…. If you want one, go and make it yourself.

And then you could replace A/B pruning with MCTS-like search (let's call it PUCT)
And then you can adjust minibatch size to increase speed.
Wait, isn't that Leela?

Yeah and likely stronger.
BTW, is there a parameter to change "eval\nn.bin" ?
90% of coding is debugging, the other 10% is writing bugs.

Re: A hybrid Stockfish NNUE?
Yes, that's certainly possible. And you'd end up with an engine much weaker and slower than SF-NNUE running on CPU.Dokterchen wrote: ↑Tue Jul 21, 2020 2:44 pm I wonder if it would be possible to make a hybrid version of Stockfish NNUE, with the search running on CPU and the evaluation on GPU.

Gee, how come after founding this forum and being on it for 20 years you still can't use a search function???
