Re: Chess.com 2018 computer chess championship

There's no indication that the CPU engines will be given full access to the anemic CPU machine during games against Leela.
Fortunately, that wasn't the point I was making ;)....

Re: Chess.com 2018 computer chess championship

Well, all the other engines won't be sharing resources while playing LC0, so she will face engines with 40-something "real" threads with no memory or disk contention. On the other hand, while the conventional engines will face weaker competition than Leela, they will also be weaker when doing so... ...

Re: Chess.com 2018 computer chess championship

I'm quite familiar with hyperthreading. My concerns remain. Indeed.... Ponder is bad enough when threads < physical cores, but with using hyperthreads contention is guaranteed. The real danger is not in CPU though, but concurrent TB access.... unless each program gets its own SSD with its own copy ...

Re: Google lets you put TPUs in your own machine

Yeah, I can't imagine why anyone would buy into that platform when Nvidia cards are there, which handle a much, much wider array of compute tasks with an already robust ecosystem. Or even next gen AMD cards will likely be far more generally useful. But whatever... people are free to sell their wares...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

Hold out for the next gen cards.

Either will get better perf/watt & absolute performance, or will very likely be able to buy previous gen cards for cheap as they become 2nd tier for mining.

Re: Run LC Zero in LittleBlitzerGUI

The amount of memory for hashing is the resource
Exactly like the presence of a GPU ;).

Re: Run LC Zero in LittleBlitzerGUI

What about hash size? Different engines take up different amounts of space per TT entry. If one is more efficient than the other, then assigning a fixed amount of hash size to both engines will result in one having few entries available and thus be at a relative disadvantage. Perhaps each engine sho...
