Re: Dramatic drop in performance with LC0 after updating Cuda drivers

Actually I did download what was the latest Cuda drivers from Nvidia … I think it was version 10. But somehow installing those drivers installed like 8 different subsets of drivers, including Physix (or something like that) and a bunch of other stuff that I have no clue what they were. Most likely ...

Re: Deus X Neural Network Progress

How has the progress of the 'Deus X' neural network been going? Block sizes, Games, Current plans, Playing Style, Elo, etc ... With no selfplay games I would guess that progress may be a little slower in terms of improving strength. PS: Would be nice if you developed a website / blog. Hi Ted, Thing...

Re: Does Leela Chess Zero analysis depend on the processor?

Quite probably it depends on the phase of the moon. AZ search would make a good random number generator. Miraculous that the threads and the parallelisation manage to work at all. but they do. Maybe Crem can explain the algorithm. You are right, the randomness in Lc0 is very large. Would it be poss...

Here was my commandline: lc0-v20rc2.exe --cpuct=3.4 --backend=roundrobin --backend-opts="(backend=cudnn-fp16,gpu=0)" --minibatch-size=512 --weights=11250.pb --nncache=5000000 --threads=3 --smart-pruning-factor=0.000 Your election of parameters --cpuct=3.4 --smart-pruning-factor=0.000 is better than...

Re: My non-OC RTX 2070 is very fast with Lc0

No, in the second case there was no GPU usage for sure. Roundrobin is a new multiGPU option I used in v20, and that is remarkably efficient in single-GPU as well. Here was my commandline: lc0-v20rc2.exe --cpuct=3.4 --backend=roundrobin --backend-opts="(backend=cudnn-fp16,gpu=0)" --minibatch-size=51...

Re: My non-OC RTX 2070 is very fast with Lc0

OK, something seems off. Why are the 2080 depth 17 nodes so many more than the depth 19 with the 2070? Maybe I am missing something. Thanks. Probably different nets used. But the speed should be fairly uniform with the latter test30 nets, so nps are probably fair to compare. I used 11250, which I h...
