I'll just rent em when I need em. :-)
It was funny, tho. I read someone talking about all the "nosql" databases,
and how people were complaining SQL doesn't "scale". He said "SQL scales
fine. What the people mean is that SQL doesn't scale if you want to use a
commodity piece of hardware like Amazon rents. This is what we have in my
office for testing:" and gives the stats on a 96-CPU 256G RAM SQL processor.
He says "That's the low-end base machine for testing, not the production
system."

Well, a 24GB system is expensive but main-street now.
(I built one in june): based on i7 implied triple channel memory, and
therefore most single i7-supporting motherboard are limited to 24GB.
Finding a set of 6 Ram-stick to fill the slots is rather easy too, as
memory-maker/seller make kit ready to install (and with warranty).
Motherboard: about 200€
Memory: about 800€
CPU: anywhere from 200 to 1000€
Box: from 50€ to 200€ (according to the cooling and other
easy-life-making: hand-screw, clip-on...)
and so on for the small details (mouse, keyboard, graphics card(s),
display...)
There you go, a system with more than 16GB.

Presumably that's not x86 though.

I didn't look into it that deeply. Why would you think it's not?

I got the impression that x86 CPUs are designed to communicate with only
a fixed number of peers.
For example, a socket 939 Athlon can only be run in a single-chip
configuration. But a socket 940 Opteron has an extra pin which enables
it to run in single-chip or dual-chip configuration. (But not
triple-chip or more.) In later Opteron generations, part of the model
number tells you what the maximum number of chips you can wire together
is. I gather Intel Xeon chips use a similar system.
Given that the reviews talk about 1-chip, 2-chip, 4-chip and even
8-chip, I very much doubt anybody has bothered to design a 96-chip part.
Who would they sell it to, after all? (And wouldn't it need 96 extra pins??)

I wonder if POV-Ray 3.7 could be compiled for this monster:
http://en.wikipedia.org/wiki/Jaguar_%28computer%29
It has more cores than the maximum number of threads POV-Ray would use for
an average-sized image (iow. you basically get a core for each square to which
the image is subdivided by POV-Ray for rendering).
A giant poster-sized image could perhaps require rendering more than one
square per core...

I think the first job should be rendering a 300 DPI 1:1 scale image of the
computer it ran on. :-)
