...if it calculates it's own impact on the enviornment into it's calculations.

 

Seriously, how damn important is predicting the weather? Is a few points of a percentage accuracy really worth the cost? Oh gee, I might not have my umbrella one day when it rains. Golly.

 this is for nataional weather not News at 9.

 

But hey if you don't want people to know about he huricane out to sea that will hit sire in a week go ahead shut down the super computer. And when THOUSANDS DIE because they didn't see the huricane until it was on their doorstep you better be ready to explain to alot of people why the shut down the machine that predicsts that kind of stuff.

If the British Met Office shut down the supercompter people would then start complaining about inaccurate weather reports, so either way some one is going to bitch no matter what.

I think there's a couple zeros missing.  According to the top 500 list, that thing tops out at 156 Tflops, not 1 as stated in the article.

Actually, it's about the most power efficient you can get if you don't want to spend a whole bunch of time re-writing your software for the GPU or Cell.  It's a BlueGene/P system, and they crank out 372 Mflops/Watt.  The cell offers 536 Mflops/Watt, but I'm sorry to say that those supercomputers are going the way of 8 track tapes.  They're simply too hard to program for, and people simply don't want to invest the time requred to port the codes over when they could be running simulations instead.  So, the next generation, BlueGene/Q, will simply be multi-core CPUs.

So this thing can do what equilibrates to 1 TFLOP (1000 * 10^9 = 10^12 = tera-). Pretty pathetic in the world of supercomputers.

An nVidia Tesla 1U server can crank out an average of 3.935 TFLOPS and it consumes 0.067% of the amount of power this weather supercomputer does. Hell even at double precision, you'd only need 3 of 'em and consume only 1,200 W...not 1,200,000 W.

 

As such, I'd venture that this thing is pretty old.

 if you math is correnct how much would they have to invest to upgrade :-)

Also what would they need to transfer their softwhere?

 

It's a interesting quandry

I would imagine that the expense of "upgrading" would be well worth
the savings (at $0.07/kWh cost @1.2MW = $84/hr vs. @2.4kW $0.168/hr).

 

However, I'm inclined to go with penguinboy 156TFLOPS is much more reasonable for a supercomputer.

I would like to get the pc on my f@h team!

all through the time of weather forcast a large %  of the forcasts are wrong... it will stay that way .. that is the nature of weather

 

how many times have you been told.... gonna be a bright sunny day ... as it is raining

i'm not saying some people do not need the weather forcast.. i am saying that no matter how much money and computer cycles are thrown at forcasting, it will often be wrong

*sigh* when are people going to learn you cant have both ends of the spectrum..least not yet, you cant have a fuel sipping car and go 0-60 in 3 seconds. Just as you cant have low power usage and compute the world. i like the gpgpu idea however while the watt per packet of data my be a huge leap, the total wattage may increase if a symilar physical space is used as the present super computer.  also most of the energy goes to cooling not the actual processing.

There is a man in Britan that can predict severe weather a year in advance. He is suppose to reveal his formula on Oct 28, 2009. ABC News did a story on him. The address to the video is below. If this comes out then they might not have a need for the supercomputer anymore.

 is that a shot of the british super computer or stock? If it's the former those look pretty modern, cant do much there if it's the latter i bet all these new low TDW processors and GPUS would cut that footprint in half.

Give me a break. What do people think you need to predict weather patterns, a Blackberry? It takes serious computing power to run those models, and super computers don't run on AAA batteries. This whole "Green" movement is getting rediculous. We need to conserve where it is practical, but accurate weather prediction can save lives, so this is not the place to let the tree-huggers impose their uninformed will on the rest of society.

the very nature of weather makes it dynamic changing continuously. those models you speak of look good on paper but 5 min into a weather event they are worthless, again the nature of weather

 

if you are going to pound on a drum maybe you should find one that is worth pounding

Sounds to me like another self-generated story created in an effort to get new funding. Busybodies in government are always looking for new "problems" to solve.
