What is LHC@home?

This a volunteer computing project that uses Internet-connected computers to advance Particle and Accelerator Physics. Participate by downloading and running a free program on your computer. By default, you can run the classic LHC@home application Sixtrack, for simulations of accelerator physics, and help researchers at CERN to improve the LHC.

Other LHC@home simulations that utilizes virtualization to run applications for Theory and experiment simulations for ATLAS, CMS and LHCb are also available.

Please note that some of the applications on LHC@home requre Virtual Box to be installed. Please visit the LHC@home information site for more information. If you have any problems or questions please visit the Message Boards, Questions and Answers and FAQ.

Interruption to CMS@Home, Wednesday 15th July
We need to interrupt the CMS project tomorrow to deploy a new Workflow Management Agent. This means that jobs will not be available from sometime tonight. We recommend that you set your CMS machines to No New Tasks as soon as possible, to avoid tasks terminating with an error if a job can't be fetched.
We anticipate jobs will be available again late Wednesday (European time). I'll update this thread when it is OK to proceed.
