I've been to New Mexico, and it's nice enough if you are into desert (I liked it fine.) But...
a) As was alluded to in the article, self-sufficient in 5 years? I expect it'll be obsolete by then, unless ongoing upgrades are planned. Most machines on the top 500 are off the list within 2 years except a few that were built out and expanded. I simply wonder what demand there is for buying time on a cluster that is 5 years out of date.
b) The bigger issue... This isn't the 1950's. Ya don't walk up to the computer operator and toss them a stack of punch cards or a tape to feed into equipment physically connected with the machine. The two ways I've seen of feeding in info: 1) Internet connection. Sounds ridiculous, but internet2 has 100 gigabits per second on all links and some other research networks have similarly ridiculous speeds. 2) One place I've visited that does astronomical interferometry, they have a crap 56k leased line (making option 1 impossible), so the remote stations send hard disks* via UPS to the central station for processing, then the central station sends them back. As the old saying goes, "Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway."
*The station I visited actually still uses tapes. They were sent a box of Deskstars, the one guy there pointed out Deskstars are crap, he was told they'd be fine, and on the first run about 75% of them croaked. Apparently the central office never replaced them and just had them use the old reel-to-reel tape drive instead. I can't make something like this up 8-).
