Now that the Knights Hill has been cancelled, what does the future roadmap for the Phi look like? Should we be considering future Phi upgrades for our systems, or is the Knights Mill essentially end of line?
Knights Mill 7235/7285/7295 are a variation designed for deep learning. They are not the successor to the Knights Landing but a supplement to it.
As for whether that's the end of the line, I think you'd need a crystal ball to answer that one. However the USDE Aurora computer is supposed to be fitted with the successor to the Knights Hill design in 2021 so there's at least that.
