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. In order to run these, you need to install VirtualBox and enable the additional applications in your LHC@home project preferences.

Please visit the LHC@home web site for more documentation, data and instructions. If you have any problem, question or doubt please visit the Message Boards, Questions and Answers and FAQ sections of the project.

CMS Jobs working again
It's been a few hours now since the Data Bridge appears to have been fixed and jobs are staging out normally. You can resume running CMS tasks at your will. 18 Jul 2017, 17:16:35 UTC · Comment

CMS@Home -- please set No New Tasks and perhaps temporarily run another project
There is a problem staging-out CMS@Home jobs to the Data Bridge. Until we find the cause, please set your CMS crunchers to No New Tasks, or temporarily move them to another app or project.
Sorry for the trouble, unfortunately it's beyond my capability to resolve.

No RESULTS accepted from Linux Kernel 4.8.*
As an emergency measure and over the weekend, I have set
max_results_day to -1 for all hosts running Linux (Ubuntu?)
Kernel 4.8.*. SixTrack is consistently crashing with an IFORT run
time formatted I/O error. This will avoid wasting your valuable
contributions. Eric.

CMS application job queue is being run down.
We want to update the WMAgent job controller, so I've stopped the next batch (I hope). We should run out of jobs in 10-12 hours, so set any machine running CMS tasks to No New Tasks as soon as practicable. Should be up again tomorrow. 26 Jun 2017, 15:59:30 UTC · Comment
