Yesterday I sent Harm Geert a PM and asked him if he can make an account for LCZero. He was online this morning and probably missed the PM.
This evening I can set it up, I don't have any experience with LCZero, it probably needs more than 1 thread to make full use of the GTX-1080ti.

Re: On-line engine blitz tourney April
With 1 thread my GTX 980 claims to be at 89% usage (according to nvidia-smi; I don't know how reliable that is). So I didn't bother figuring out how to use more threads.Joost Buijs wrote:Ah, I didn't notice it was a guest account.AlvaroBegue wrote:No, that was me, making sure that I could run it if someone asks me to.

Maybe mamer can be modified to turn off the tourney variable for all participants after the tourney is finished.Volker Annuss wrote:If you leave your engine online after the tourney is over, please check if your tourney variable has been reset.
Enteringmakes sure, your engine is open to accept challenges.Code: Select all

It is supposed to already do that, I think.

Re: On-line engine blitz tourney April
Just give it -tn on the command line. With the 1080ti using 3 or 4 threads seems to be optimal, after a full tune I get around 3500 to 4000 n/s on the initial position.AlvaroBegue wrote:With 1 thread my GTX 980 claims to be at 89% usage (according to nvidia-smi; I don't know how reliable that is).

I want to try to make a modified version which uses cuBlas, this might be better optimized for nVidia. A nice experiment for a rainy day.

Re: On-line engine blitz tourney April
You are primarily going to need convolutions, which cuBLAS doesn't do. But cuDNN does, so perhaps that's what you meant. A cuDNN implementation on a GPU with tensor cores (Titan V or V100) should go much much faster.Joost Buijs wrote: I want to try to make a modified version which uses cuBlas, this might be better optimized for nVidia.

Re: On-line engine blitz tourney April
You are right, I didn't know that nVidia has a specialized library for deep-learning. If it can make use of the Volta tensor-cores it probably runs a lot faster. I wonder if the new (still to be released) consumer GPU based on Volta (GTX-20XX?) will have tensor cores or not.AlvaroBegue wrote:You are primarily going to need convolutions, which cuBLAS doesn't do.

The current version of LCZero (v0.7) doesn't seem to make very good use of the GTX-1080ti, at max. ~50% GPU utilization, so there is still enough room for improvement.
This morning I run some test games on HGM's server, it plays a decent game, very strong openings but a clueless endgame. With just a few games it is difficult to get a grasp of how strong it actually is, my guess is that it is around 2700-2800 Elo on the CCRL scale.
