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.

I started crunch BOINC in November 2014 after I was talking to a friend about the waste of hardware that was catching dust rather than do something...

CMS@Home up again
OK, jobs are available again. Sorry for the long delay. Remember, I'm only the front-man for a larger crew, so any downstream delays percolate up to my response. Hopefully this will remain good for some time, but I still don't understand why the condor server occasionally refuses to send out jobs in a timely manner.

CMS@Home accidentally shut down -- Please set No New Tasks
We need to upgrade the CMS@Home WMAgent before Thursday, so I tried to set the workflows to drain down. Unfortunately, I misunderstood the batch states and killed off most of them instead. :-(. There's one still left with about 200 jobs, so that won't last long.
Please set your CMS projects to No New Tasks to avoid getting lots of computation errors. I'll let you know when the upgrade is done and jobs are flowing again.

Server outage - uploads failing
Due to a network problem in the CERN computer centre early Thursday morning, our BOINC servers have lost access to a storage cluster. Hence uploads are failing and access to web pages as well. Hopefully this should be fixed soon.

CMS@Home disruption this week
It appears that a database intervention at CERN went badly, leaving our data tables empty and us not being able to submit new CMS@Home jobs. Advice is that it will take several days to recover -- and as well as that some of the major players are in the USA, which has holidays for the rest of this week. I'll keep an eye on it, but I'm doubtful we'll be running again this week. Sorry 'bout that!
Happy Thanksgiving...

Database intervention Monday morning
LHC@home and associated BOINC services will be unavailable for about 1 hour on Monday 25th of November due to a database storage intervention.

Thanks for your understanding and happy crunching.
