What is LHC@home?

This a research 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.

Server upgrade - file uploads paused
We will change the storage back-end on our BOINC servers today, and the file servers will be disabled during the operation.

Hence your BOINC clients will get not be able to upload or download files from LHC@home today for a few hours. Once our maintenance operation is finished, BOINC clients will be able to upload again.

Thanks for your understanding and happy crunching!

Theory application reaches 4 TRILLION events today !!
LHC@home's Theory application today passed the milestone of 4 TRILLION simulated events. This project, under its earlier name "Test4Theory", began production in 2011 and was the first BOINC project to use Virtual Machine technology (based on CERN's CernVM system).

We will be publishing some more details for you on the LHC@home and CERN websites over the coming days. Here is a first release:

Many thanks to all our volunteers for enabling this achievement !

CMS Job queue draining
Due to a problem with the WMAgent submission task, a new batch of CMS jobs is not being put in the Condor queue. So, the queue is now draining and there will be no more jobs available in a couple of hours. Best to set your BOINC instance to No New Tasks if you can, to avoid spurious compute error terminations.

Task creation delayed - database maintenance
Due to a database issue last week, task generation is delayed and we need to clean up stuck workunits. The project daemons will be on and off this morning while we try to debug a problem with the BOINC transitioner.
