Re: Chess NNs In Humans And Programs

There is the same concept of shapes, straight/diagonal movement in NNs too. The way residual neural networks work is that the top layers figure out basic shapes and movements and the following layers figure out increasingly complex concepts. I am sure I have seen visualization of a chess ResNet that...

Re: Intel AMX with TMUL on Xeon Sapphire Rapids (2021?)

Indeed that could definitely help some. I actually do it for the endgame when the number of pieces <= 14. With many divisions other than opening/midgame/endgame though, there is going to be lots of redundant knowledge encoded in each net. Handwritten evals seem replaceable with NN on the CPU now, bu...

Re: Intel AMX with TMUL on Xeon Sapphire Rapids (2021?)

The NNUE stuff probably could probably benefit a lot from it. But I have my doubts with how far you can with that approach with such a tiny net. At some point, you have to increase the net size to improve further, which then necessitates use of MCTS over AB .. I don't have the energy to implement NN...

Re: Help with Scorpio 3.0.8

Another good news is that we may have reached 3000 ccrl elo! I was actually surpized to find this out yesterday because I was thinking maybe it is 2500 elo. Selfplay elo on the webiste is as we all know inflated. The net is starting to beat 2-thread Scorpio alpha-beta. If that result persists we hav...

Re: Help with Scorpio 3.0.8

Well, the good news is that the new version is using the GPUs very well: C:\Users\dannc\chess\nn-dist-master\Scorpio\bin\Windows>C:\Windows\System32\DriverStore\FileRepository\nv_dispsi.inf_amd64_86e7a5db5f94798e\nvidia-smi Wed Jun 24 01:27:59 2020 +-------------------------------------------------...

Re: Help with Scorpio 3.0.8

No harm :)

I feel like only the most patient people such as Dann get through the complexity of Scorpio.

One problem is I don't have or can't even rent a machine with GPU and windows so problems pop up there
now and then.

Re: Help with Scorpio 3.0.8

The egbb files (egbbdll64.dll and libnnprobe.so) will be in nnprobe-windows-gpu/. The client.bat calls the installer script if it can not find the Scorpio/ folder under the nn-dist/ directory. So to reinstall Scorpio, all you have to do is remove the Scorpio folder and call client.bat again. The thr...

Re: Help with Scorpio 3.0.8

I do not seem to have this problem on a windows CPU machine though. Maybe multi-gpu mode is broken somehow, but I think you updated scorpio with last version that added resign. I haven't touched anything that affects multi-gpu mode since then. Unless you did not do a full reinstall of Scorpio (maybe...

Re: Help with Scorpio 3.0.8

Ok I will check what is wrong with the windows version.
Btw you have to run "scorbio.bat" not "scorpio.exe", the latter will segfault.
So do this from the bin/Windows directory

Code: Select all

scorpio.bat go quit
Cliff and Gary are able to contribute with the new binary but they are both running on linux.

Re: Help with Scorpio 3.0.8

Dann, we updated the client and you need to reinstall Scorpio too, or you could just copy the windows exe from zip file: https://github.com/dshawul/Scorpio/releases/download/3.0/scorpio30-mcts-nn.zip and overwrite the scorpio binary you have in bin/Windows. This may be a better option than reinstall...
