Re: TCEC Lc0 Configuration

I repeated your test on my machine. It has dual RTX 2060 GPU. Dual RTX 2060 practically has the same chess power as a single RTX 2080 Ti has. I used lc0_v0.21.2-RC1 and T40.T8.610 net file for test. Parameters are: Backend=multiplexing Backendoptions=cudnn-fp16,(GPU=0),(GPU=1) NNCachesize=9900000 (f...

Re: TCEC Lc0 Configuration

If Backend = RoundRobin it is enough 3 threads for two cards. As "TCEC.jpg" shows the value of position is 2.83 pawns for White. But as "one RTX 2080 ti.jpg" shows your machine displays only 1.00 pawn advantage for White. I think you do not use T40.T8.610 net file as TCEC does it. Or maybe your net...

Re: TCEC S15, END of an ERA event is much more Brutal than I thought!

It's comical to see people rate chess engines by their performance in TCEC. TCEC is pure entertainment. Many specialized opening suites already exist to do proper testing. TCEC has only two issues: 1, !00 games are too few to get an exact Elo 2, They use opening position what were selected on their...

Re: T40.T8.610 net for TCEC15 SuFi

Among developers of Leela and among the fan of Leele was a long dispute about which net would be sent to TCEC final. There were peoples who thought T40.T8.610 would be the best because it is optimized to 7 men syzygy and there were peoples who wanted to send the last 42xxx net. I made a test between...

Re: Bluefish vs Leela in TCEC , who will win? BF =170 Threads, Lc0 =2x GPU
