My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

This week I updated three of those posts — two really old ones (primarily of interest to computer architecture historians), and one from 2018: July 2012: Local and Remote Memory Latency on AMD Processors in 2-socket and 4-socket servers. December 2013: Notes on Memory Bandwidth on the Xeon Phi (Knights Corner) Coprocessor.

On July 5th 1982, Leslie Lamport (initial LaTeX developer, Microsoft Researcher and winner of the 2013 Turing Award), Robert Shostak and Marshall Pease published a paper named The Byzantine Generals' Problem. Several system architectures were designed that implement Byzantine Fault Tolerance. The Byzantine Generals' Problem.

The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. twitter.com/slightlylate/status/1139684093602349056 455 06:18 AM · Feb 28, 2020.
