The fact that you built it demonstrates it's not "off the shelf" - it's a
custom build. ;-)

Yes. Now go to Best Buy and buy a system based on that system board.
That's what I'm talking about when I say "off the shelf". I can get
laser pointers pretty much anywhere I go, but to get something more
powerful, you have to go to a place like Wicked Lasers - yes, you can buy
stuff "off the shelf" from them, but they're a specialty vendor, which is
my point.

It seems nearly all boards for i7 take up to 24 GB, and certainly in the
"mainstream" shops here you can buy i7 systems for a normal price.

Yes, a conspicuous number of supercomputers use Opteron and not Xeon.

I meant that the CPU has to be designed to operate with X number of
peers - so you'd have to design a Opteron or whatever with pins for 96
other peers. Which presumably AMD haven't done.

"The 75xx models have four QuickPath interfaces, so it can be used in
up-to eight-socket configurations, while the 65xx models are only for up
to two sockets."
Also... They make 8-core Xeons now?! o_O I bet those a cheap.

Bugger that:
http://en.wikipedia.org/wiki/List_of_AMD_Opteron_microprocessors#Twelve-core_Server_processors
Heh. 12-core chips in a 2- or 4-socket configuration? That's, like, 48
cores or something! That's crazy...
(Then again, last I heard Opteron isn't as fast as Xeon.)

Shows how recently I've purchased a system. :-)

I actually have pretty free access to about 50 computers of about this
capability, but exactly the opposite problem -- not enough free time to
do any serious POVing that would warrant their use.

Surely there's profit to be made there! ;-)
