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.
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.
test of SixTrack 5.00.00
we are in the process of testing a new sixtrack version, i.e. 5.00.00. This is a true upgrade of the code, which has been re-factored deeply - including dynamic memory allocation. Moreover, it provides fixes to the physics already implemented, e.g. solenoidal fields and online aperture checking, and brand new implementations, e.g. electron lenses and ion tracking. We are finalising the implementations, hence the version running as sixtracktest is a quick test of the main functionalities and code re-factoring.
More to come in the next days / weeks.
Thanks a lot for your precious help!
Keep up the good work, and happy crunching!
Alessio, for the SixTrack team

CMS production pause
We have run into a problem with the CMS project -- the merged result files processed at CERN are failing to be written to central storage. Consequently I have decided not to submit any more jobs until the experts have clarified what the problem is. The CMS jobs queue is about to start draining and I expect it to be empty of volunteer jobs within a few hours (there may still be post-production jobs, but these run at CERN, not on your machines). I suggest you set No New Tasks or transfer to another project until the situation is resolved.

Server upgrade - file uploads paused
We will change the storage back-end on our BOINC servers today, and the file servers will be disabled during the operation.
Hence your BOINC clients will get not be able to upload or download files from LHC@home today for a few hours. Once our maintenance operation is finished, BOINC clients will be able to upload again.
Thanks for your understanding and happy crunching!

Theory application reaches 4 TRILLION events today !!
LHC@home's Theory application today passed the milestone of 4 TRILLION simulated events. This project, under its earlier name "Test4Theory", began production in 2011 and was the first BOINC project to use Virtual Machine technology (based on CERN's CernVM system).
We will be publishing some more details for you on the LHC@home and CERN websites over the coming days. Here is a first release:
Many thanks to all our volunteers for enabling this achievement !
