Re: Intel AMX with TMUL on Xeon Sapphire Rapids (2021?)

Sorry, I deleted the post you referred to....here it is... A simple trick to increase accumulated NN size could be to split the NN into opening, middle and endgame, up to 30 distinct NNs indexed by piece count for example. -- Srdja Indeed that could definitely help some. I actually do it for the end...

Followup...

Fujitsu put 32 GB HBM on their ARM based A64FX processor with 1 TB/s

Re: RMO - Randomized Move Order - yet another Lazy SMP derivate

Just a further remark...

RMO will probably not profit from SMT, Hyperthreading, with an overall NPS
speedup of ~1.5x, my experiments with Zeta on gpu showed at least 1.8x is in
need.

Re: GPU rumors 2020

Seems Intel plans to boost NNs on CPUs not only via AVX-VNNI but also via its upcoming AMX, Advanced Matrix Extensions, maybe with the new Xeons in Aurora supercomputer aimed for 2021... https://www.tomshardware.com/news/intel-powers-on-sapphire-rapids-processors-scheduled-for-2021 we will see how t...

Hi all,

I can’t get into GitHub this morning, I’m getting Oops 500 and a Server Error?

Is this just me, or are others having problems?


Thanks,

Al.
Had the same issue here from Germany, now it works again for me.

Because a lot of eval patches are written with (losses against) Leela in mind.
Yea, evolution and co-evolution. I guess LC0 and SF will become a kind of binary-star.

Re: Running Leela and Fat Fritz on your notebook

There are external GPU solutions via Thunderbolt out there, just google for it.... regarding performance: http://talkchess.com/forum3/viewtopic.php?f=2&t=72696&p=824192#p824192 I was thinking of getting a 2 in 1 laptop with an external gpu (2080ti) connected to thunderbolt or a desktop with the 2080...

Re: GPU rumors 2020

Yea, despite the talk about the death of Moore's Law we still have the 5nm and 3nm fabrication process in pipe, and maybe some unknown reserve, hence some 2^3 8x improvement of NPS for neural networks within 10 years possible...not to mention new kind of combinations of search algorithms with NN, or...
