Re: Question for Nelson Hernandez - TCEC power consumption

Seriously, I've been trying to get an answer on this question for close to a year now. Somebody must have some kind of measurement of this thing. Anyone? TCEC, two machines, 1) CPU-centric, 2) GPU-centric. What is the electricity draw of machine 1, machine 2?

Question for Nelson Hernandez - TCEC power consumption

Question: What is the precise power draw from the A/B machine and the NN machine in the current TCEC 15 Superfinal? We can calculate this value based on hardware specs, but I want to know based on actual measurements, such as with a Kill-A-Watt or similar. Even better, I'd like to see a power use gr...

Re: CPU vs GPU...fair play...keep it simple

Equal power consumption. That is by far my number one criteria. After that would be memory; each machine should get the same amount of memory. I think eventually hardware prices, which are driven by marketing, tend to level out. So I think CPU vs GPU should be judged by watts drained out of the wall...

Leela Ratio and wattage

Does the Leela Ratio reflect CPU vs GPU watt usage? https://blog.lczero.org/2018/07/04/leela-ratio/ I.e., if a computer running Stockfish compared to a computer running Leela Zero registers a Leela Ratio of 1.0, and then we measure power usage of each computer (say using a Kill A Watt meter), will t...

Re: Cfish 9 is OUT!

How was the rusftish source created? Is it generated from the C++ source, or is it hand built?

Re: Stockfish / Glaurung abstract base classes

If you're curious, this "abstract base class" is a concept from the realm of object oriented programming. For instance, you might have a program part of which deals with bicycles. In particular, say you have some mountain bikes and some road bikes. Some things are different between those. Perhaps on...

Re: "Intrinsic Chess Ratings" by Regan, Haworth --

Wow guys, thanks so much!! I was seeing some discussion of the "rating inflation" question over on the Chessbrah forum (on a "Discord" server). Some basic googling led me to the 2011 paper but nothing more recent. Your feedback (particularly from an author!) is much appreciated!
