LHC@Home

(Also called LHC @ home 1.0, LHC @ home 2.0 Test4Theory and Sixtrack ) LHC @ home is a distributed computing project for ( distributed computing ), which simulates the passage of particles through a 27 km long particle accelerator. The aim of the Large Hadron Collider be optimized. It runs on BOINC, a platform for projects of distributed computing.

This particle accelerator (Large Hadron Collider) was put into operation in September 2008 by the CERN research institute.

The LHC @ Home client simulates 10,000, 100,000 or 1,000,000 passes of 60 particles through the particle, which corresponds to 1 second, 10 seconds and 100 seconds in real time. The program calculates whether the particles remain stable in orbit or hit into the wall of the vacuum tube and so could damage the LHC. The results are used to verify the stability of the particles in the LHC and provide data for the adjustment of the magnets.

On 29 September 2004, the project took on its official operation. The aim of the CERN it was in the early stages to win 50,000 users within 50 days. As a little incentive to participate CERN 's T -Shirts were therefore daily raffled among the users, also on October 18, 2004 edition of the anniversary book " Infinitely CERN - Memories from 50 years of research".

Although the project missed its target ( in November 2005 were 21,000 registered participants ), LHC @ home was continued. The server infrastructure was from the year 2006/2007 to August 2011 at the University of London. Since August 2011, the server infrastructure is back at CERN. In March 2008, the project had 88,000 registered users. The current computational power of the Sixtrack project is 25 teraflops (June 2013), which can vary depending on the daily output.

To analyze the data obtained in the four experiments of 15 petabytes per year, the Worldwide LHC Computing Grid is used, a form of a grid. In the spring of 2011 was started with LHC @ home 2.0 another platform with the data obtained by the LHC should also be analyzed by the BOINC community. The first project, which is run on the LHC @ home 2.0 platform, called Test4Theory.
