Re: A more interesting question about GPU verses CPU

To 'compare' algorithms you should first define a metric for algorithmic complexity. You seem to focus (completely arbitrarily) on the number of multiplications. One might just as well only consider the number of branches. With the same number of branches per second, Stockfish would not be a match ...

Re: A more interesting question about GPU verses CPU

For a chess engine, which gives more Elo per dollar? The other measurements are not nearly so important. An even better measure would be the quality of analysis per dollar, but that would be much harder to pin down. For me the most important measure is tera-flops, as I am only interested in algorit...

Re: Instruction for running Scorpio with neural network on linux

I am getting link failures like below though I am pretty sure that I have followed all the steps. Also some people have reported such errors and suggested the solution is to add _all_ lib files that tensorflow produces. https://github.com/tensorflow/tensorflow/issues/15013 I will try that if there ...

Re: Instruction for running Scorpio with neural network on linux

The compilation failed after 5 hours while building the Eigen library. Any ideas ?

Re: Instruction for running Scorpio with neural network on linux

Thanks! Though I was using 2015 community edition, it didn't come with the SDK.
The cmake configuration went through after doing that and also installing python.

Re: Instruction for running Scorpio with neural network on linux

Fyi building tensorflow_cc for windows is not very straightforward (easily takes a whole weekend), but possible. What we did for LCZero is described here: https://github.com/glinscott/leela-chess/issues/334#issuecomment-382848569 I've just read in TCEC chat that not having windows build is the reas...

Instruction for running Scorpio with neural network on linux

Hi, I just added notes on how to run Scorpio with neural network evaluation on a linux machine here https://github.com/dshawul/Scorpio#nns No idea how to do this on Windows since tensorflow_cc does not support it. The easiest way is to use the docker images but you could also build and install the t...
