I know teacher, I know!! Can I answer, pretty please??

Bruce McCulley <[EMAIL PROTECTED]> asks:

Precisely! (Except that I'm not a psychologist, so I don't know if
you're delusional or not :-). You can buy 8, 16, or 32 processor
systems (at 731MHz, currently...), and then subdivide them into
8 processor chunks if you so choose, by using some console commands.
Note that the larger systems will tend to have more than one PCI box
(and each box holds a dozen or so PCI slots, but a given box can go
to only one of the partitions.). So, if you want 2 partitions, you
need at least 2 PCI boxes, so long as you have at least one PCI box
per partition. The CPU chunks are actually divided into "QBB" - quad
building blocks of 4 CPUs and some associated memory, although
it is technically a NUMA configuration, so the configuration permutations
get a bit crazy. The QBBs all talk to each other and the memory and
the i/o on a very large, very fast crossbar switch.
One of the marketing tools that we employ is selling incremental
capacity, wherein customers are shipped a system with 16 CPU's, but
have 8 of them turned off by the software license. If they want to
buy (or rent) the incremental additional capacity, we send them the
appropriate software license (for Tru64 UNIX or OpenVMS, not Linux).
So, yeah, it's a pretty incredible machine... I have fun with mine,
believe me.
