Re: Breaking news from Caruana, Leela is essential part of his preparation

Breaking news - sounds like a joke,
due to the fact that nearly every chess player on earth know: chess pros are using Leela.

Breaking news: They are using also Stockfish, Houdini and Komodo :shock: :shock: :shock:

Re: Scorpio 2.8.9 with TensorRT support

Does it loses many elo points when using int8 precision calculations?

Re: Scorpio 2.8.9 with TensorRT support

Hi, Scorpio 2.8.0 MCTS+NN with TensorFlow and TensorRT backend is available here https://github.com/dshawul/Scorpio/releases Changes: a) Implemented TensorRT backend with the option of FLOAT/HALF/INT8 precision calculations. There are now two formats for the network UFF on the GPU, and PB on the CP...

Re: One piece sacrifice by Leela at move 12. (she gains material back in 50 ply later)

Yes but you need a 44 core tcec Stockfish to beat LC0 on rtx 2080 ti.
If LC0 could use int4 in a good way, it would be stronger than Stockfish with 44 cores.

This has already been answered. The lower precision comes at a cost.
How to improve this?

Why LC0 still can't use INT4?

This would improve the speed by a factor of 4.
For example:
RTX 2080 Ti = 36k speed.
With INT4 = 144k speed.

How long do we need to wait for INT4?

Re: Lc0 speedup on 2 GPUs

With a normal alpha beta engine running on a CPU, it is well known that a doubling of cores has a search efficiency cost. Stockfish on 2 cores is somewhere around 1.8x faster than on 1 core (though the nps will be about double). What is the equivalent with Lc0 going from 1 graphics card to 2? Maybe...
