Re: Scorpio MCTS+NN: What are the strongest nets?

I have never really measured its strength honestly because all I do is check if it works by running it through a set of epd positions. I have nets trained from about 25000 games (actually set of epd positions) called nets-epd and from about 0.7 million CCRL games (nets-ccrl) that can be downloded he...

Re: Tactical 'weakness' of LC0 in a recent CCCC game

I came here to laugh at LC0's blunder but then i realized scorpio-mcts-nn on a P100 makes exactly the same mistake. It does a 14kn/s using a 6x64 net.

Re: Scorpio 2.8.7 MCTS+NN windows version

I have made some significant work with GPU acceleration of NN evaluation in this version. Multi-threaded batching as I have described in the programming section helps a lot and now scorpio can be launched with upto 256 threads even on a 4-core machine and a single GPU and perform well. I get 10kn/s...

Re: Scorpio 2.8.7 MCTS+NN windows version

There maybe an issue with networks trained from PGN games (CCRL games) . I have mostly been using another set of networks that I trained from set of EPD postions. This set was also used for training standard scorpio's eval. Could you try the net-2x32.pb file contained in https://github.com/dshawul/S...

Re: Scorpio 2.8.7 MCTS+NN windows version

Hi Daniel, I played some games against lc0 on 6x64 net too: Lc0-1 9154 1CPU - ScorpioNet : 14,0/14 14-0-0 (11111111111111) 100% +1200 :( by the way: can Scorpio read weights_9154.txt.gz renamed to net-6x64.pb ? Lol ok -- i guess i shoulda expected that. Turn off neural network usage (use_nn=0) and ...

Re: Scorpio 2.8.7 MCTS+NN windows version

Fantastic!!

That is another thing off my shoulders.

Now I can go back to my linux machine and fix multi-gpu issues, as well as making the cpu to
use more cores efficiently.

Thank you very much !

Re: Scorpio 2.8.7 MCTS+NN windows version

Nice!! Lets try and get the gpu version working. Daniel I have now made it so that the necessary CUDA 9.2 dlls come pre-packaged as well. If you have a GPU already, you should have the driver i.e. nvcuda.dll so no need to put that in. The process for installing egbbdll for the gpu should be equally...
