According to the information on the website it consists of 48 Origin2000
with 128 CPU's each. Each machine has 12 HIPPI-800 ports, connected via a
3-dimensional torodial interconnect (with 36 16-port switches).
The flyer notes that they plan to upgrade the interconnect in 1999 to
HIPPI-6400 and 32-port HIPPI-6400 switches.

4-way machines according to the information I found. Looks like they have
a new "machine" on their way, with a total of 5856 CPU's (1464 4-way SMP
machines) for "closed side" (classified stockpile stewardship computing ?)
>From the information it looks like they have 2/3 of these already, which
should put that relatively high on top500 list if it had been included.
Both uses 4-way 332 MHz PPC604e, but there were old notes about planning
to move to Power-3 in "1998". Looks like that have been delayed thought.

Lots of interresting links in that top500 list :-)
