I've seen reference to them, but I have no idea how rare they are.

I do animation and video. Splitting up the processing into 100 frames
per job or so (depending on the project) I can easily keep a large
cluster busy. There's no processor-to-processor communication going
on at all. I usually have a large amount (gigs) of read-only data
that all processes need, and mmap() that, so 14 processes run very
well on an E4000, sharing one copy of the data.
Some jobs get threaded instead, but I avoid that when possible.
The CM-4000 did get scaled back though, after I saw my electric bill
one month after running two nodes for a couple of days straight...
I've decided that two maxed E4000's is sufficient for now.
