[email protected] consists of two applications: [email protected] Classic, SixTrack, which went live in September 2004 and is used to upgrade and maintain the particle accelerator Large Hadron Collider (LHC) of the European Organization for Nuclear Research (CERN), and [email protected] 2.0, Test4Theory (now is Virtual [email protected]), which went live in August 2011 and is used to simulate high-energy particle collisions to provide a reference to test the measurements performed at the LHC.
The applications are run with the help of about fifteen thousand active volunteered computers processing at a combined more than 15.5 teraFLOPS on average as of June 2014. [email protected] uses idle computer processing resources from volunteers' computers to perform calculations on individual workunits, which are sent to a central project server upon completion. The project is cross-platform, and runs on a variety of hardware configurations. Virtual [email protected] uses VirtualBox, an x86 virtualization software package.
