It is very surprising that even after 1 year, progress is still going on. If Deep Mind didn't end the project at the end of 44 million games, we could see a much strong AlphaZero chess engine.

Impressive indeed.

I'm curious, have you done any duplicate test runs at any point using 12 threads instead of 20 threads on the Ryzen, to see if the results are the same with SMT, and any analysis on the games re average depths etc ?

If you would read the testing-conditions on my website, you would know, that the NN-Testruns are not running on a Ryzen CPU...

Using less threads? Duplicate tests? Definitly not. Waste of time and resources.
Analyzing games? Feel free to do it. All games can be downloaded on my website. All played moves with eval, depth and thinkingtime.

Yes I know the NN testing is done on your Intel machine. It was more of a general question on the other testing that you do on the Ryzen.

I remember that Alphazero trained only 24 hours and turned that monster (today it has already been overcome). But imagine if Deep Mind left A0 training longer with the resources they have? I think it would reach a level beyond the limits of reality, don't you think?

OK.
The point is, on 99% of all notebooks, it is not possible to switch off hyperthreading. And so, on a 12 core machine, you have 24 virtual cores and there is no way, to use the 12 hardware-cores directly. And the OS distributes the computing power in very small timesnippets to the virtual cores. So, when playing engine-matches with an time-increment, the move- and calculation time is much, much longer and this means, each thinking engine gets "the same peace of cake" from the CPU.
No need, to worry about that.
And using only 12 cores would be just a waste of CPU-Power.And the engines still would not have direct access to a hardware-core, but to virtual cores. So, this makes no sense at all.

TCEC has switched to using 0.27.0+68653 finally.

I played match against J94-130 in GTX card 60+0.6:

Code: Select all

                  
1   68695     +16  +17/=123/-10 52.33%   78.5/150
2   J94-130   -16  +10/=123/-17 47.67%   71.5/150

68695 has 45% higher NPS.
