A Look At CERN's LHC Grid-Computing Architecture 53
blair1q writes "Using a four-tiered architecture (from CERN's central computer at Tier 0 to individual scientists' desk/lap/palmtops at Tier 3), CERN is distributing LHC data and computations across resources worldwide to achieve aggregate computational power unprecedented in high-energy physics research. As an example, 'researchers can sit at their laptops, write small programs or macros, submit the programs through the AliEn system, find the necessary ALICE data on AliEn servers, then run their jobs' on upper-tier systems. The full grid comprises small computers, supercomputers, computer clusters, and mass-storage data centers. This system allows 1,000 researchers at 130 organizations in 34 countries to crunch the data, which are disgorged at a rate of 1.25 GB per second from the LHC's detectors."

I was having lunch with some CERN guys a couple weeks ago, and was asking them about the speed of their analogue to digital converters. I don't remember what the number was, but it seemed low to me, something like 200kHz. So, of course, I had to point out that *my* cheapo converters ran faster than theirs by more than an order of magnitude. They responded with "well, each of our converters does 200kHz on all of our 4000 channels at the same time, so we're really recording at..."
They won.

Your post makes me wonder about a future where I have a home computer powerful enough to run an algorithm which downloads as many tracks off of iTunes as it needs and then can compute by extrapolation the future hits of RIAA, before they are released.
One wonders whether the courts would find that such a program is a circumvention of DRM for the purposes of the DMCA. Unfortunately, the computer, which can answer that question, will be destroyed by the construction of a .....
