when you spend a significant fraction of your budget
on non mass-market hardware.
IMO, of course, and I know I'm presenting an ultra-orthodox position,
but that's the whole point of philosophy. purity not practicality ;)
to me the point of Beowulf is the hack factor:
using mundane hardware that's been cheapened by volume production
to do work traditionally done with very specialized, expensive boxes.

I'd argue it's not, but I know most Beowulfers would disagree.
I'd even argue that SCSI, because of it's prepetual 2-3x premium,
is not beowulf material.
sure, Ultra160 is way cool, as is Myri2, as are 21264's.
but you won't find any of them in my local computer store...
