Re: NNs seem to solve the Gusev Qxe5!! easily.

On the other hand, I have positions where NN engines toil for an hour without finding a tactical solution that alpha-beta engines find in a few seconds. When you only have a hammer in your tool kit, everything looks like a nail. A point often purposely (or otherwise) overlooked by NN advocates. Nei...

I think this is a key position in the game. White has many possible moves.
Hmmm...

I'm not sure there was a key position, but if there was I'm pretty sure this isn't it.

Re: Space/Time Tradeoff in year 2020+: What can the community do with 20TB+ Hard Drives?

It's long been the case that it's more cost, time, and power efficient to store every root position that's analyzed longer than a second. This includes all position not already stored in an EGTB even if 128 byte records are used. The analysis is a little more complex for non-root positions but many...

Re:Cost of 256gb ECC Rdimms

https://www.newegg.com/nemix-ram-256gb- ... 003Z-016M2

So about $20K to fill 8 dimm slots. 2P systems would cost about $40K to fill assuming only 8 dimms per CPU socket.

Re: My predicted 3rd Gen threadripper prices

Looking at this board: https://www.gigabyte.com/us/Motherboard/TRX40-AORUS-XTREME-rev-10#kf I think maybe you could put 4x 2080 supers in there. Of course, that would eat up ALL of your PCIe 4.0 slots. I suspect that there may be (or will be) PCIe 4.0 GPUs available. With the doubled bandwidth of P...

https://www.pcmag.com/news/371784/seagate-will-ship-18tb-and-20tb-hard-drives-in-2020 While there has been a lot of talk about new CPUs, GPUs and maybe flash storage (or "optane") technologies, hard drive progress continues to march forward. Seagate will release 18TB "Conventional" Hard Drives next...

Re: My predicted cost/performance ratios

Approximate cost performance ratios for the R9 3900X, R9 3950X, Threadripper 3960X and Threadripper 3970X for a new build with a RTX2060 super and 64GB DDR4-3200 ram. The only specs that differ is the CPU, MB (AM4 vice TRX40), and power supply is larger for the two threadripper systems. Does not inc...
