Re: GPU recommendation needed

I have a dual-Xeon system with 2 Intel Xeon E5-2686-V3 cores or 2 X 18 = 36 cores total. I would like to add a decent GPU card so as to test lc0 but not reach for the top (GTX 2080). What would be recommended in terms of a value purchase: GTX 2070; GTX 2070S; or is there an AMD GPU I should look at...

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

Jhorthos is building and training larger and smaller than the default 256x20b T40 nets, one can download them here: https://github.com/jhorthos/lczero-training/wiki/Leela-Training On several test suites, which combined, were pretty faithful to longer time/position in assessing strength of different...

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...

I can do the tests but I'm doing it with CB, so I need .cbh and not epd or pgn.
And a link where I can download opening200revised and arasan21beta. Others are welcome too.

Re: Leela outplays SF Dev in a position that SF evaluates as draw

Having said all that, I don't think SF is totally off the hook yet. It just sounded like SF was being criticised for not having an evaluation of e.g. -2, when -2 is probably totally wrong. SF (W) & Leela (B) play to this position: 3r4/pp4k1/1bn1Rr1p/6p1/5p1P/1NP2P2/PP1R1P1B/6K1 w - - 1 11 SF thinks...

Re: buying a new computer

I am looking for a new computer since it has been a while. I saw a 2990wx with 16 GB ram, 2080ti, 500 SSD drive for 3k. Overall do you think this is a reasonable deal? Will this be a good setup for a few years? I know new chips are coming out, but will this be good "bang for your buck"? I know a fe...

Re: buying a new computer

It's better to buy DDR4 32 or 64 GB RAM.

Re: 320x24 Jh net is doing well in cccc bonus. Good news for upcoming T60 series!!

As it is early era of NN, no one knows the optimum size of network for current consumer hardwares. Although 20x256 are much stronger than 10x128 in 20xx RTX hardwares, bigger networks did not do well previously. It is the first time to see this bigger net 320x24 doing well in cccc. It is a very goo...

ScorpioNN v2.9.0-n_maddex_INT8 is great:)

INT8 is much better than FP16.

Some days ago at TCEC:
Scorpio INT8 vs LCZero1pct v0.21.2-n42547 +0 =4 -0
Scorpio INT8 vs LCZeroCPU v0.21.2-nLD2 +0 =4 -0

Now Scorpio INT8 vs LCZeroCPU v0.21.2-nLD2 +1 =1 -0

Will LC0 ever use INT8 instead of FP16?
