Re: SSD Problem

Thanks for the info. I have been booting back and forth for many months with no problems. I did find the Easeus recovery tool and ran another recovery tool also (MiniTool Power Data Recovery). There are between roughly 13 and 39 million files on the drive (depending on the tool). I don't actually ne...

SSD Problem

A setback. Looking for a good disk recovery utility. My 1TB SSD had 300+ GB free, but WinRAR and tar could not expand anything saying it was full. This was under both Win7 and Ubuntu. The disk was Win7 NTFS. It was strange. Got the notion that Win7 disk defrag might help. It ran for 3 days... Things...

Re: EVGA GeForce GTX 950 2 GB

I know next to nothing about laptop video cards. That said, personally, I would never run Leela for any long time on a laptop at all. For desktop gpus, I would not bother with any over-clocking or "free" bundled games. The question is the number of fans or the sealed one with just the one fan (these...

Re: EVGA GeForce GTX 950 2 GB

While I am no expert, some general suggestions. Firstly, Leela specifically benefits from some optimizations known as "fp16", which roughly triples the speed in nps. The newer RTX 20XX series cards support this. The older 10XX cards do not. A value-priced option instead of the 2080ti would be a 2060...

Now type "go wtime 5000" and hit enter. If it does a little search then your all ready to install into your chess GUI.
Perhaps you meant go "movetime" 5000" instead of "wtime".

It is playing fine under Winboard.

Is there a specification for the file format used by Syzygy which could be used to independently write probing code?
Yup. Right here:

Re: Chess Fighter Neural Net release

I am no UCI expert, but it might not matter if the engine makes the moves as the GUI will send the position and an appropriate move list each time anyway, I think. Was having some trouble under Arena. Tried under Winboard. Does run, but moves instantly. Have go head off to work. Will look at it agai...

Re: Chess Fighter Neural Net release

Tried with Win7. Had to copy cudart64_92.dll and cublas64_92.dll into the directory. Always searches for around 38,000 nodes for me, regardless of go <w,b>time n command Appears to be making the moves, which should not be done. Some --help info would be, well, helpful. A very good start. Did you use...

Re: Super bullet chess: LC0 v0.21.0 network 41619 vs newest Stockfish dev 200319

With Ponder On and SF getting 4 cores, and Leela typically using 2 cores, just wondering if this was a 6 core system?
Thanks.
