Re: Is the 320x24b larger net the strongest around for RTX GPU?

There is a basic problem to make test match with longer TC than blitz: You need a hardware with huge RAM. Leela has a very unpleasant behavior namely her memory usage enhances together with the playing time. When you use Leela for infinite analysis it is a natural phenomenon but if you make a conse...

Re: buying a new computer

The huge memory usage of Lc0 is a returning theme on the sites of LC0. But this is the first established answer for it. Why, Dear "crem"? Is it so great secret? I can not believe the developers of Leela can not make modifiable the usage of RAM with an UCI parameter. Maybe it would decrease the Leel...

Re: buying a new computer

I don't think lc0 consumes that much memory and from my calculations it could go upto 17 hours analysis with just 12 gb ram. Thats one of the reason i decided to stick with 16 gb ram. Daniel 1 node takes 250 bytes, or in other words 1GB is needed for 4M nodes. (and also one NN cache entry takes 350...

Several alternatives suggested by Stockfish would have also lost it the game (say, MultiPV shows 0.00 for 3 alternative moves, but one of them loses, how do you decide what to play? And if Stockfish is one move away from randomly...
