Leela - Best Practice

[Stephen Ham]

Hello All,

On my home PC, I was advised that with just one GPU, I need two CPUs. So, that's the way I operate.

However, I may soon have access to two high-end GPUs. Then, should I step up to a total of four CPUs (retaining two CPUs for each GPU), or is best performance obtained with still keeping just two CPUs? I see that in TCEC where Leela has two GPUs, only a total of two CPUs are retained.

Thanks in advance for your advice.

In GTX card 1 cpu has always been better in bench and testsuites! Never trust recommendation, but test itself .

Just to be pedantic, it's cores not CPUs.
Which cards are you using? On a 4090 a core is almost as fast as 2, so maybe one core per GPU is best.

To be even more pedantic, I think you'll find it is threads not cores
