So who is gonna write that concurrent self-play client, you? Do have any idea how much effort is required to do this properly without introducing further bugs? I guess you don't...

That's done already - try:

lc0-cudnn selfplay --parallelism=8 --backend=multiplexing "--backend-opts=cudnn(threads=2)" --games=1000 --visits=800 --tempdecay-moves=10
you can also pass different arguments for both players by adding "player1: --argument=x player2: --argument=y"

You should really tone down your language and insults, Milos - why don't you contribute instead of complaining? Let us all see your awesome skills.

We are talking about official LCZero client not CUDA branch from Alex that is anyway already using batching on single instance, because self-play games so far are only played by official client. Multiplexing batches with CUDA is easier, with official LC0 you'd have to rewrite OpenCL part from scratch.

lc0-win-20180519-cuda92-cudnn714-00.7z

Thank You, that was very helpful.
Which CUDA Installer should I use, the exe (network) or exe (local) ?

I used local. It is a big install, with some unnecessary items such as the Visual Studio extras. Don't worry if it complains it can't find it. Once all is installed, including cuDNN, you need to locate three DLLs in all, and copy them in the LCZero folder:

cublas64_92.dll
cudart64_92.dll
cudnn64_7.dll

After that just enjoy LC0 in https://crem.xyz/lc0/ Be sure to configure its UCI options, including the path of the weights file. For example, mine shows: C:\Users\Albert\Chess\LCZero\weights.txt.

Feel free to use the optimized settings described in a previous post in this thread.

Hello,

I thought I installed everything needed but couldn't find/locate the 2 following dll's:
cublas64_92.dll
cudart64_92.dll

Where can I find them/download them from ?

I have now found them and copy them to the same folder as LC0. Unfortunately, I still dont see any increase of nps....?
Any idea what I am still missing?

Nothing. With Cuda 9.2 Leela is only 5% faster, than with Cuda 9.0. No big difference.

I think he meant only 5% faster than the Open CL (non-CUDA) LCZero. So something is wrong.
