How To Use a Terabyte of RAM

Spuddly writes with links to Daniel Philips and his work on the Ramback patch, and an analysis of it by Jonathan Corbet up on LWN. The experimental new design for Linux's virtual memory system would turn a large amount of system RAM into a fast RAM disk with automatic sync to magnetic media. We haven't yet reached a point where systems, even high-end boxes, come with a terabyte of installed memory, but perhaps it's not too soon to start thinking about how to handle that much memory.

    Finally, I'll have enough space to run Firefox, OpenOffice, and Eclipse *all at the same time*! As long as I don't leave Firefox running too long.

      Of course, there's quite a few complete operating systems that can boot in the amount of RAM required by emacs :)

      Yes, but they're substantially less functional operating systems than Emacs.

      Fortunately, you can run vi inside emacs, so it does indeed have a good text editor.

    I have 8 GB of RAM and rarely use more than four of it unless I'm playing a 64-bit game which eats it up (Crysis). Yes, I am running both 64-bit Linux and Windows.
