Re: CEGT - rating lists July 14th 2019

Note that Stoofvlees doesn't support pondering (yet), so I would expect it to be weak in pb=on rating lists.

Re: Ryzen 3000 series is out

Yes, otherwise I don't understand the scores. Do they say if they allowed the Boost? i9 9900k on 1-2 cores can go to 5.0GHz, while Ryzen 3900X 1 core to 4.6GHz. If they allowed the boost, many single-thread benchmarks will look bad for Ryzen in this comparison. Leela is a curiosity in this benchmar...

Re: Ryzen 3000 series is out

I'm already talking about the revised numbers. The original ones (now deleted) showed that the 3700X was the same speed as the 2700X, which obviously couldn't be true.

In the new data it clearly gains, but not enough to catch Intel.

Re: Ryzen 3000 series is out

AnandTech included SPECint2017 benchmarks, which include Deep Sjeng: https://images.anandtech.com/graphs/graph14605/111160.png The results were...surprisingly bad, i.e. clearly worse than Intel cores. I wonder why. This is one thread benchmark? It's actually a bit confusing: "Moving on to the 2017 ...

I wonder if the BMI2 slowdown is finally fixed.
PEXT/PDEP still take ~18 cycles. You don't want to use those.

Re: Is Blas, or OpenCL really the right way to go

I hope they drop OpenCL and switch to something that doesn't crash when doing clGetPlatformIDs, so I can run GPU Leela at all. If your drivers are broken then switching APIs isn't going to fix it. I assume you're not on an NVIDIA card or you'd use the CUDA build, so what hardware is it, and what dr...

Re: Finally, Norway found the solution to end all agreed draws

I dunno about you but I watched 4 classical games that lasted for hours and ended up drawn because the players were saving their energy for the Armageddon.

Then the Armageddon was a crapshoot especially Aronian - Grischuk.

Solution looks worse than the problem to me.

Re: armageddon in norway chess

BTW do you know, if the armageddon games count for the blitz ratings, or if they are simply discarded for blitz elo? (Or may be, if this becomes an adopted new way for future tournaments they will create a new list?) The details for URS are not published but from the high level description such a s...
