Re: Fritz 17

Werewolf mentioned some odd behaviour with Fat Fritz, possibly a bug in the NN or it just needs an Update.
Not buying it till all the bugs are ironed out.

Re: Fat Fritz Flummoxed

Different weights = different results I suppose. But don't you think there is a possibility that there may be something wrong with the NN that your Fat Fritz shipped with, if its getting flummoxed so easily ? Maybe you should ask Albert Silver or Chessbase for an urgent Update for the Fat Fritz NN....

Re: Fat Fritz Flummoxed

I was advised by Albert to use either 3 threads with RoundRobin or 4 threads with Multiplexing. I tried both and Multiplexing was slightly faster. I've also tried Lc0 here and it gets it very fast. Different weights = different results I suppose. Fair enough. And Yes, the weights definitely matter....

Re: Twin 2080Tis and large NN

I don't think everything is cut and dried as far as lc0 is concerned and there are a lot of variables involved. And I don't choose my opponents ; I play them as they come. It's thrilling enough for me to DEFEAT AB engine users using an AI Engine using GPUs, something which just a few years ago every...

Re: Fat Fritz Flummoxed

Is it proven that Multiplexing is better for 2x 2080 Ti? Not only better, it is REQUIRED if you are using TWO 2080 Tis ! If you select cudnn-fp16 in backend, ONLY ONE, the Primary GPU will be utilized by lc0, causing a drastic reduction in Kn/s. ONLY when Multiplexing( or demux or Round Robin) is e...

Re: Fat Fritz Flummoxed

TCEC use 3 threads for 2x RTX cards. Also why do you use not use fp16`? Are you talking to Werewolf or to me ? Anyway, glad to know TCEC uses 3 Threads like me. But Werewolf (and I) are correct to use "Multiplexing" in Backend and not just cuddn-fp16,as we are both running TWO 2080 Ti cards togethe...
