U.S. to build world's fastest computer
Spinner
Birmingham, UK
Viewing supercomputers as crucial to scientific discovery, the U.S Energy Department will announce plans today to build the world's fastest computer at a research laboratory in Tennessee.

Yea, but will it overclock well?Energy Secretary Spencer Abraham was to make the formal announcement in a speech Wednesday, in which he will call development of the world's fastest computer for general science "critical to our nation's competitiveness."

N82E16819103428 $689.00
$1,378.00
Subtotal » $ 7,896.98
So, basically, each node has:
2 2.2GHz Opterons
8GB of RAM
550.5GB of RAID 5 disk space with 15,000rpm disks. For $8,000 each.
Divide 400,000,000 by 7,896.98 and you get roughly 50652. So say 50,600 nodes. Which would be a total of:
222,640GHz
404,800GB of RAM
27,855,300GB (that would be 27,855 TERABYTES) of hard drive space
Now, according to www.top500.org, a 2816 node, 2GHz Opteron cluster has a theoretical maximum speed of 11,264 gigaflops, and an actual benchmarked speed of 8051 gigaflops.
If you scale those numbers to the cluster I just outlined, you get a theoretical maximum speed of 222,640 gigaflops, and a real-world speed of about 159,133 gigaflops.
To put that in perspective, the current top supercomputer, the NEC Earth Simulator, does 35860 gigaflops, with a theoretical maximum of 40960 gigaflops. In other words, the beowulf cluster I just outlined would be about 4.4x faster than the current fastest supercomputer. That is Hella Fast (highly technical term).

The software used is probably Open Source, so cut total cost in half versus cost with proprietary software. Lessee, weather modelling takes OOODLES of storage, so does complex modelling like atomic particle research, TAX compliance records and figuring out who owes what, etc. Guess is, they need it for complex stuff and are not talking about the details of how complexe it is.
AFAIK, NEC included software costing also, at a guess this budget is hardware only and they are getting bulk discounts in massive percentages-- you get to bid to sell that kind of thing to gov't, and for that large-cluster kind of purchase some of the mfrs probably bid direct sale bids. AMD will happily sell units of 1000 Opertons to anyone with good money to spend. And WD will and does bid direct sales to gov't. Etc....
this article cites a 25 million dollar budget:
