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. 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.

sixtrack_validator
There will be a (very) short interruption while I
install a new sixtrack_validator. Should fix null/empty
fort.10 and the nasty "outlier" problem.
See SixTrack Application, sixtrack_validator for more news and details.

SixTrack Tasks distribution issues
Please see Message boards:SixTrack application, thread
"SixTrack Tasks NOT being distributed". This is to have one place for
all relevant messages. This thread is for SixTrack only.
My first post reports my personal status.

Network and server problems Sunday night
We had a network problem in the computer centre at CERN last night, leading to a number of issues for our servers. BOINC servers should be back in business now.

Normally tasks should be correctly uploaded again on the next attempt. If you see any issues, please try an update or reset of the project.

Sorry for the trouble, and happy crunching!

SixTrack News - May 2017
The SixTrack team would like to thank all the teams who took part in the 2017 pentathlon hosted by SETI.Germany:
https://www.seti-germany.de/boinc_pentathlon/
where LHC@Home was chosen for the swimming discipline. The pentathlon gave us the possibility of carrying out a vast simulation campaign, with lots of new results generated that we are now analysing. While the LHC experiments send volunteers tasks where data collected by the LHC detectors has to be analysed or Monte Carlo codes for data generation, SixTrack work units probe the dynamics of LHC beams; hence, your computers are running a live model of the LHC in order to explore its potential without actually using real LHC machine time, precious to physics.

Your contribution to our analyses is essential. For instance, we reached ~2.5 MWUs processed in total, with a peak slightly above 400kWUs processed at the same time, and >50TFLOPs, during the entire two weeks of the pentathlon. The pentathlon was also the occasion to verify recent improvements to our software infrastructure. After this valuable experience, we are now concentrating our energies on updating the executables with brand new functionality, extending the range of studies and of supported systems. This implies an even increased dependence on your valuable support.

Thanks a lot to all people involved! We count on your help and committment to science and to LHC@home to pursue the new challenges of beam dynamics which lie ahead.

LHCb application is in production
We are very happy to announce that the LHCb application is out of beta and is now in production mode on LHC@home. Thank you all for your precious contribution.

We are grateful to have you all as part of our project.

Please, refer to the LHCb application forum for any problem or feedback.

Thanks a lot
Cinzia
