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. I guess they compiled for BMI, but SSE3 builds will be 25% faster. What you are sayi...

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...

Re: Why are super top professional Go players so stupid?

I thought that setting komi (KM) in the SGF file is enough to make Leela play with desired komi. Wrong! Leela engine doesn't support komi setting, it is designed with fixed komi 7.5 and no handicap. Not only that, all the networks are trained to play well only with this komi of 7.5 and no handicap....

Re: Why are super top professional Go players so stupid?

I am pretty amazed having this thing on my PC as free open source software, that's why I posted here. These human players I am writing here about are Gods, and my stupid irreverencies please me :lol: . The most amazing thing IMHO is that in chess, we had ~15 years or so to get used to computers gra...

Re: Why are super top professional Go players so stupid?

If they use only OpenCL and not CUDA (cuDNN) that's really... unclever. :lol: :lol: :lol: :lol: :lol: I believe Ttl/Henrik Forsten has a CUDA+cuDNN version in one of his github branches. AFAIK it is slower or at least the performance difference was completely uninteresting. On RTX cards the OpenCL ...

Re: Question to Remi about CrazyZero

If I understand correctly, Leela Zero and Leela Chess Zero have become a fork. They would probably have made faster progress together if they had kept the same code for both games. Most definitely. There's several things implemented in one engine that aren't implement in the other, both ways. Forki...
