Re: Scaling of Lc0

The main question to me is, how does Leela play chess? AB engines calculate, and the more cpu power they have, the more can be calculated (theoretical) Leela seems to be different. Maybe I am wrong, but it seems like Leela is searching in her weights file. BAsed on what can be found there, the actua...

Scaling of Lc0

Me again I am quite new with Lc0, but highly interested. What could be the ELO benefit from 1 x RTX 2070 to 2 x RTX 2070 ? In analysis I noticed that the main line does not change after 10 - 20 seconds. So maybe the benefit is very low compared to energy hunger and the investment of a second RTX car...

Re: how to run Lc0 on two RTX 2070 ?

Gee, how can you guys be so clueless???
Its okay to be clueless. Forums like ccc can help with experience, thats one of the reasons to be here.

Giving advice while being clueless is human :D

how to run Lc0 on two RTX 2070 ?

Hi there
does anyone know how to run Lc0 on two RTX cards?
Are they automatically detected? Or is there a need for setting up parameters? If so, which one.

How many RTX cards does Lc0 support?

thx in advance for help.

Re: Lc0 v0.20.2 (33003) Vs. Stockfish 080219 64 POPCNT

Hi

is it really 16GB hashtables for Stockfish??
I think its too high for that time controll. Will not affect the game too much.
Thinking per move is average 1min?

Anyway, thx for the match.

Lc0 and future of rating lists

Hi All

I am curious about what the rating lists are thinking about Lc0?

A list is quite incomplete, as long one of the top 1-2-3 is missing.

Isn't it time to add Lc0 based on e.g. RTX 2060?

regards, C.K.

Re: Stockfish Cluster MPI

Thanks Timo I am a little rusty about all those things, times of ClusterToga are long gone. I will install Win10 on the second machine. To create a UCI engine the runcmd program is needed. Also I have to install my Mellanox InfintyBand cards and create a subnet. Think it has to be done in the Window...

Re: Stockfish Cluster MPI

Question: Why does it start like a normal engine? should this engine start in consolemode only if MPI is installed ? regards, C.K. Ahh I tried to compile it like normal stockfish :p I turned on MPI in the makefile and also checked during the compile it said mpi: 'yes'. Hope this one works. :) https:...
