Yeah, I convinced the moderators to update the link to a newer version of the paper. But keep in mind that a paper published in 2013 probably describes research performed in 2012 on hardware purchased in 2011 (if they're lucky). Getting back to hardware, the premium for 4-socket servers appears to be much smaller than it used to be, so now you can get a ton of DIMM slots for a reasonable price.
I'm confused. I think the link changed to a different version of the paper. The numbers I went by aren't even in there any more!
