CERN Collider To Trigger a Data Deluge
slashthedot sends us to High Productivity Computing Wire for a look at the effort to beef up computing and communications infrastructure at a number of US universities in preparation for the data deluge anticipated later this year from two experiments coming online at CERN. The collider will smash protons together hoping to catch a glimpse of the subatomic particles that are thought to have last been seen at the Big Bang. From the article: "The world's largest science experiment, a physics experiment designed to determine the nature of matter, will produce a mountain of data. And because the world's physicists cannot move to the mountain, an army of computer research scientists is preparing to move the mountain to the physicists... The CERN collider will begin producing data in November, and from the trillions of collisions of protons it will generate 15 petabytes of data per year... [This] would be the equivalent of all of the information in all of the university libraries in the United States seven times over. It would be the equivalent of 22 Internets, or more than 1,000 Libraries of Congress. And there is no search function."

And 60% of it will be porn.

The real fundamental question is not about beginning of the universe, but something much much more important: Are they going to backup the data?
On the other hand, I'm sure it will be available on some torrent soon.
You know with the right sort of particle accelerator you could send messages straight through the Earth and save a heap of latency.

Lepton dancers wearing gluons.... WHOA!
Would that be 0.84 Internet per forthnight? Or 1 kiloLibrary per Congress session? How much in tubes?
Well, yeah, but the probability is about the same as that of you generating a small black hole by clapping your hands together really hard.

This is really bad news. By defining the amount of data in LoC's, they leave themselves open to a huge exploit... If the LoC ever includes this data, then there will be a recursive loop of definitions and the LoC will expand to fill the universe.
Okay... maybe not, but if they ever did put this data in the LoC, the effort required to re-factor all the LoC based measurements would bankrupt the world. And the confusion that goes on while this re-factoring is happening will surely crash at least one probe into Mars, where the English have used the new LoC units and the Americans will have used the old LoC units.
We are from NASA, and would like to offer you a job in mission planning.
Igor Presnyakov stole my hat
it will generate 15 petabytes of data per year...
Umm, question. Is this BEFORE or AFTER time stops?

The problem is that CERN will generate more data than it can afford to hold on it's own server's hard drives. If they had an A380 (Airbus for teh win ;-)) worth of hard drives installed and ready to tap data, they would not need to move all that data.
and heard the sound of one hand clapping put together.
Don't be daft. Everyone here at UU knows that the sound of one hand clapping is 'cl-'

I'm sorry, how much is that in Cessna 172's again?

kilodelta, I have someone I think you should meet. His name is Werner Heisenberg, and he's got some ideas that may interest you.
Reality has a conservative bias: it conserves mass, energy, momentum...
Sounds like the article was written by Senator Stevens. Nothing to fear, 22 emails can't possibly clog our tubes.

My quantum computer has been working on downloading the torrent for the past few weeks.
Hmmm witty sig or funny sig? Maybe elitest techy sig!
That's a lot of tubes.
oh marmalade.
- Okay, so that's 15 petabytes *tapping on calculator* that's 3.4x10^29 bits.
- Taking the maximum data rate from a given node as 3 gigabits per second, and taking into account the effect of bandwidth increases over time.. *tapping on calculator*
- Okay, and taking the average mosquito lifetime as 20 days.. *tapping on calculator*
- *breaks into a cold sweat*
- Now, assuming mutations in mosquitos occur at a rate of 1 base pair per generation, *tap tap tap* and that our genes are different from mosquitos by 2.4x10^6 base pairs.. *more tapping on calculator*
By the time they have transferred this data to scientists across the world mosquitos will have become the new dominant species.// MD_Update(&m,buf,j);
