I am going out on a limb here, but I suspect that a majority of the
people on this list lean far more toward the casual administrator types
and not professional cluster admins. Often, I suspect, the issues of
power and cooling only arise in times of scarcity and not out of some
anal-retentive need to quantify resources. They are very likely people
doing science (or other worthy endeavour) and simply use clusters as
tools. Should one quantify the ROI on each pencil and pen in ones
office? I realize that the first pen/pencil in your office is an
important writing device, but why do you have a second and third, given
that the useful life of a pen/pencil, under normal load, is quite
I'll be right back as soon as I justify the dozen or so pens I have
under the seat of my car. Hold it! I don't use the company's crappy pens
and provide my own. I guess beans don't interest me.

If you get a visit from the Meanie Beanies (auditors / cost accountants etc etc) then it'll help cover your A. It's a great way to have your gig cancelled because you didn't have a firm understanding of your $'s in and out. Happens all the time in Industry and in my job it's a sackable offence. No joke. Do some homework and you won't need to be afraid (OK, *as* afraid of the Purple Pen People).
