looking for Lc0 newest Version

Hi. How would you know if Lc0 is using your CPU or GPU? Cheers.

Simple! The dnnl & openblas versions-we were talking about-are CPU only. Cheers!

That's why you need a GPU. On my low end RTX 2060...

Thank you.

Hi. How would you know if Lc0 is using your CPU or GPU? Cheers.

Sorry for the confusion. What I meant was "How would one know if Lc0...". Cheers.

From ChatGPT:

When you run Lc0, it will output some basic information about the device it is using. For example, if Lc0 is using a CPU, you will see something like this in the output:

Code: Select all

info string CPU Backend: nn-x86-64

On the other hand, if Lc0 is using a GPU, you will see something like this:

Code: Select all

info string GPU Backend: CUDA

In addition, you can also check the usage of your CPU or GPU while running Lc0 by monitoring the system resources. For example, you can use the Windows Task Manager or the Linux command-line tool 'htop' to monitor the CPU and GPU usage of Lc0. If you see high GPU usage, it means that Lc0 is using the GPU to accelerate its computations.

That's explains it, thanks!
