Great that it's so easy to configure.

Re: How good is the RTX 2080 Ti for Leela?

Thank you ! Can you or someone else explain me what is fp32 and fp16 and how to set that? Is that also existing with other GPU such as the 1080Ti and or 1060 ? rgds Small update, Ankan added the 2080 to his benchmarks: with cudnn 7.3 and 411.63 driver available at nvidia.com minibatch-size=512, net...

Re: Chess.com 2018 computer chess championship

We may consider doing TB adjudication in the future. That said, our time controls are short, and I believe we've seen some interesting games and positions because we haven't adjudicated. I'm open to suggestions! Perhaps for TB draws... but for wins, let's see it played out!? For tournaments which a...

However, there do seem to be some differences with the CUDA cores between Quadro and Geforce.
Forget that comment - I see why it's wrong now.

What's FP16 accumulate?

May I recommend that you don't get a dedicated machine for chess and use Google Cloud?
How does that actually work? Can you install your programs on their systems? I can image that would get very expensive for long analysis on big hardware.

Re: How good is the RTX 2080 Ti for Leela?

It's not the CUDA cores that will be doing the FP16 computations, but the tensorcores. They are specifically designed for neural network inference, because that's what the new raytracing technique is using to make it work in realtime. Fortunately for us those cores are perfect for Lc0 as we use a v...

Re: How good is the RTX 2080 Ti for Leela?

I don't know from where people got the rumors that Nvidia crippled non-tensor fp16 math on 2080Ti. Milos has no idea what he is talking about... But it's not from Milos, it's from Wikipedia: https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units#GeForce_20_series Unless you're sayin...

Re: How good is the RTX 2080 Ti for Leela?

It should be very similar to a Titan V for lc0. It has tensor cores enabled, and it's peak fp16 tensor math throughput is almost exactly same as a Titan V (114 Tflops vs 110 Tflops): https://www.anandtech.com/show/13282/nvidia-turing-architecture-deep-dive/6 I have one, but I can't post any benchma...

Re: Fritz 13 SE?

I've just splashed out on ChessBase's Fritz 16 package. It comes with "Fritz 13 SE" already installed (as well as Fritz 16 aka Rybka 4.1). The engine dialog says it's a native ChessBase engine by "Franz Morsch". It has a few options and can only uses one thread. I've done a brief search and can't f...

Re: If you could buy any single CPU system for chess . . .

I see that TCEC now uses Dual 2699v4, which strongly suggests that the secret to CCC is "cores, cores, cores" There's no secret. Overall search speed is a function of clock speed multiplied by core count, allowing for search inefficiency as core count increases. The fastest systems will have many c...
