Data Processing at the LHC

Google Tech Talk
February 8, 2011

Presented by Bob Jones, CERN IT Department, IT EU Project Leader

ABSTRACT

CERN, the European Organization for Nuclear Research, is one of the world's largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works. CERN has recently completed the construction of the LHC, the world's largest and most powerful particle accelerator. Thousands of scientists around the world have contributed to constructing the sophisticated LHC experiments and they are now eagerly waiting to get their hands on more data to extract the physics during the next fifteen years, the expected lifetime of the LHC. To reach this goal, tens of thousands of computers distributed worldwide are being harnessed in a distributed computing network called the Worldwide LHC Computing Grid (WLCG). This supports the offline computing needs of the LHC experiments, connecting and combining the IT power of more than 150 computer centres in more than 30 countries. The rapid increase in performance of the LHC accelerator is having an impact on the computing requirements since it increases the rate, complexity and quantity of data that the LHC experiments need to store, distribute and process. The previous estimates of 15 Petabytes per year of stored data are already looking conservative and so it is necessary to plan to go well beyond this figure. This presentation will give an overview of CERN, its IT department, WLCG and how we expect the computing environment for the LHC to evolve in the future

Thanks for the talk!

13:43 40 million, not thousand. And Google: please get your audio equipment in check. People have requested this on several videos, and it cannot be an issue of cost, the quality is abysmal.

What exactly was 'promised' that they haven't delivered @lennyhome? There was and still is the prospect of finding the Higgs Boson but the accelerator still isn't even close to running at full power. Data processing takes time. Scientific research and interpretation take time. Paper writing takes time. Peer review ... you get the theme. The world doesn't become any more instantaneous by whining in youtube comments.

Excellent google tech talk as always.

Horrific quality.

[Nichev0]

@brandoconnor Then we are in agreement :)

[brandoconnor]

@Nichev0 That may be, but even so, but my originaly point doesn't change. The HB was one of the primary targets of the project but certainly not the only one and perhaps not the one which will define the endeavor when the dust settles. I'm only insisting that we haven't seen very many direct results from the LHC yet because it's still in its infancy. Give it time and the fruits of the labor will follow.

[Nichev0]

@brandoconnor It it my understanding that energies higher than are currently used are not required, and in fact detrimental, to the events thought to involve the higgs boson. Running the collider at high luminosity and gathering lots of events should speed things up.
