ORNL's Newest Petaflop Climate Computer To Come Online For NOAA
bricko writes with a description of NOAA's Gaea supercomputer, being assembled at the Oak Ridge National Laboratory. It's some big iron: 1.1 petaflops, based on 16-core Interlagos chips from AMD, and built by Cray. "The system, which is used for climate modeling and resource, also includes two separate Lustre parallel file systems 'that handle data sets that rank among the world's largest,' ORNL said. 'NOAA research partners access the system remotely through speedy wide area connections. Two 10-gigabit (billion bit) lambdas, or optical waves, pass data to NOAA's national research network through peering points at Atlanta and Chicago.'"
How much a Petaflop Climate Super Computers contribute to carbon footprint...

5-day forecasts are quite accurate. Check for probabilities, and if they're low, check back in a few days. I've been rarely surprised by weather in the last few years - as in, was expecting a warm, sunny day and got instead cold rain all day.
Depends where you live. Right off the Pacific Ocean a prediction is only good for about a day, sometimes not even that. All depends how directly a cell is moving relative to you position. Finding temperature and direction of ocean currents has a bit to say on the matters and doesn't necessarily move in a 2 Dimensional plane.
Living in the midwest, ah, you could see it coming days away. Very predictable over large land area.

It's disheartening that most of the first posters are all trolls wondering why we would ever need this or are just trying to get cheap jabs in on a site for nerds. If you don't like the science behind it (climate sciences), or you don't like the technology behind it (computing systems), then why come here to comment?
Personally, I don't put much stock in the climate modeling capabilities of it just because that is not my area of study or interest. But having another large supercomputer with interconnects running at this speed is pretty cool.
I've worked at a company that had 8 of these 10Gb waves worth of bandwidth between Chicago and NY (and at an extremely low latency), now THAT was fun! On the other hand, the prisms and optics you need in order to separate out the lightwaves were hideously expensive :)
