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.

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.

CMS job shortage Wednesday 13th November
CMS IT will be installing a new version of WMAgent on Wednesday. This will impact job availability for the duration of the intervention. We might be able to eliminate the little gremlin that's been plaguing us for the last few weeks, too.
So, please set your CMS processors to No New Tasks sometime tomorrow, Tuesday 12th, so that current tasks will stop requesting new jobs before the queues get cut. I'll let you know when jobs are available again.
Thanks.

Server upgrade
Following a couple of weeks of tests in the LHC@home development project, we are upgrading our production server cluster to BOINC server release 1.2 this afternoon. During the update we will be running with slightly lower server capacity than usual.

The SixTrack team at the LHC@Home desk for the CERN open days
Dear volunteers,

thanks to those who have filled in the doodle we circulated last week:
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5130&postid=39794#39794

We decided to deliver a presentation every day in the most populated time slots out of the doodle poll, i.e. on Sat. 14th Sep, between 03:00 and 04:00 PM, and on Sun 15th Sep, between 02:00 and 03:00 PM.
The meeting point will be the LHC@Home desk in R2 (building 504), at the beginning of the time slot. We will have to walk few minutes to a meeting room where there will be the presentations. We will be back at the meeting point by the end of the time slot at the latest.

Looking forward to shaking hands and meeting you,
Alessio and Massimo, for the SixTrack team
