There are now two projects for the LHC looking for crunchers.
"SixTrack" is the revitalized originaL LHC@home project, initially a dud, moved from CERN to U. London and basically dormant. Now, back at CERN with lots of work doing simulations of magnet tuning for the beamline to save waste in time and electricity.
LHC@home 2.0 is a brand new project. It only uses BOINC as its messenger. All the work is done in an Oracle VM (virtual machine) running Scientific Linux. It's a wee tough on Windows and Mac's, one needs to be perseverant. This project is in "beta'. This project simulates collision "events" at the four experiment centers. When it is running, the LHC produces something like 40 billion bits of data/second. Even if I am off, it is still huge beyond huge.
Anyone interested, we are in dire need of more crunchers to scale these projects up, in light of the re-design and re-build strengthening the beamline. There are posts about all of this at the ScienceSprings blog. They will ask you to visit http://lhcathome.cern.ch/ where you find links to each project. You can visit each project, look around, read some history, etc. We really are dying for help.
