Re: WHat is Stockfish VLTC time control set to?

Never mind, the link explains it:
120+1.2
I guess a five minute game with a two second increment would be called "SLCTC" for Super Long Correspondence Time Control.

Re: AMD Ryzen R9 3950X new build

I think it is a mistake to use the cost of the CPU in an attempt to determine nodes per dollar. You really need to consider the cost of the entire system. Also important is nodes per watt, because that is a real cost too. So, for instance, the new TR3 chips should probably get dinged for demanding a...

Re: get a tr3 workstation configured

A soundproofing box is less than 1000 dollars. I bought one already for my 64 core box. I want something powerful and upgradeable. I don't want to wimper when the three nanometer stuff is ready three years from now. I am interested in nodes per dollar, but I also hate waiting. Total cost is also imp...

Re: get a tr3 workstation configured

In the first link I gave, you can choose the rackmount enclosure. Even if the thing is stuffed with blinking lights, you won't be able to see them
