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.

Server outage Wednesday
Due to a failure of a database storage system, a number of database services at CERN failed on Wednesday afternoon. The LHC@home servers were affected as well, as the BOINC database was unavailable and requests timed out.

Sorry for the trouble and happy crunching!

Like many organisations, CERN is also affected by the COVID-19 pandemic. Researchers in the CERN community are trying to help out in different ways, as explained on this web page.

As part of this effort to fight COVID-19, we also contribute computing power to Folding@home and Rosetta@home from temporarily available servers that were about to be decommissioned.

During periods like this with little work from LHC@home, we also encourage you to participate in other BOINC projects such as Rosetta@home and contribute to the global fight of the pandemic.

Many thanks for your contributions to LHC@home and continued happy crunching!

With the best of wishes of good health for your and your families from the LHC@home team.

Server update
The BOINC daemons will be down for minor server update this afternoon. This is to bring our environment to the latest minor server release.

Theory application reaches 5 TRILLION events !!
LHC@home's Theory application will tomorrow pass the milestone of 5 TRILLION simulated events. This project, under its earlier name "Test4Theory", began production in 2011 and was the first BOINC project anywhere to use Virtual Machine technology (based on CERN's CernVM system).

Over the coming weeks we plan to publish some more details about all this on the LHC@home and CERN websites. Our timetables have of course been affected by the Coronavirus disruptions, but we absolutely could not miss announcing and celebrating such a milestone as this.

The whole LHC@home team sends our sincerest thanks to all our volunteers for enabling this achievement !!

Downtime Wednesday morning
The LHC@home servers will be down tomorrow Wednesday 11th of March from 6AM to 8AM UTC due to a database intervention.

Hence your BOINC clients may defer uploads or downloads. Thanks for your patience and happy crunching!
