I am playing Leela Zero on OGS, Thursday (Mar. 15) 2 pm US PST!! Leela Zero will be run on Intel Xeon E5-2690 v4 CPU, 4 x NVIDIA GTX 1080 GPU. I will be recording a video as usual.

There should be no complaints about hardware this time!

The game has been played:

The game ended with Leela Zero winning:The score B+2.5 (after komi) given by Leela seems wrong to me though because the seki in the upper right corner is counted wrong IMHO. "My" score is B+7.5.

P.S. I don't know why Haylee didn't take the upper left corner in move four.

I'm sure someone will complain the hardware is too good and gave her no chance .

[Mike Novack]

Yes, "really powerful" hardware compared to the typical home computer. But please do note, there are degrees of "really powerful". This is hardware comparable equivalent to a powerful workstation, equivalent to what some devoted gamers who have money might have. Not powerful in the sense of a "super" complex.

Also important to remember that LeelaZero was playing at about 10 seconds/move, which is really fast.
They could have easily have it do triple the amount of calculations but decided on 10sec/move.

Which basically means, if you have 1 GTX 1080 Ti instead of 4 (remember that scaling isn't linear), you can reach the same strength with just giving it 30 seconds per move, which is quite a normal time setting.

Or, with a midrange GTX 1060 you could give it about 100 seconds per move to reach the same strength.
So still very doable! My GTX 1060 gets about 800 n/s while in the game against Haylee they reported 7000-8000 n/s median.

Remember to go to zero.sjeng.org, download the client, and donate your spare GPU cycles!

I wonder how strong is LZ now - I guess at least as strong as AG FanHui version?

[Gomoto]

Leela Zero is already very strong with one Nvida 1080 Ti on a home computer, beats the currently strongest commercial available Go engine Zen 7 easily.
