What is 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.

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 jobs
The batch I submitted last night is now showing on the monitor, so you can resume tasks at will.

Warning: possible shortage of CMS jobs - set No New Tasks as a precaution
There was an intervention (i.e. upgrade) yesterday afternoon[1] on the cmsweb-testbed system we use to submit CMS workflows that left things a bit confused. One problem was fixed, and the monitor shows all good. However, we are running out of CMS jobs -- maybe 10 hours left -- but the new batch I submitted yesterday isn't showing up on the testbed monitor. I submitted another last night but still neither are being shown this morning, so I submitted yet another batch.
At the moment I don't know whether the submission has failed or whether the monitor hasn't picked up the new batches. As a precaution, set No New Tasks on your CMS project(s) to avoid tasks crashing due to lack of jobs. I'll let you know as soon as I'm sure jobs are available again.

[1] How many times do I have to tell people not to touch critical systems on a Friday -- especially Friday afternoon!?

BOINC Open Source Project Looking for Experienced Macintosh Developers
The Berkeley Open Infrastructure for Network Computing (BOINC) system is the software infrastructure used by LHC@home and many other volunteer distributed computing projects. The BOINC Open Source Project is looking for volunteers to develop and maintain the BOINC client on Macintosh. The BOINC Client and Manager are C++ cross-platform code supporting MS Windows, Mac, Linux, and several other operating systems. We currently have a number of volunteer developers supporting Windows and Linux, but our main Mac developer is winding down his involvement after many years. He is prepared to help a few new Mac developers get up to speed.

If you have Mac development experience and are interested in volunteering time to help support and maintain the BOINC Mac client please have a look at the more detailed description here: ‚Äčhttps://boinc.berkeley.edu/trac/wiki/MacDeveloper

If you are not a Mac developer, but have other skills and are interested in contributing to BOINC, the link above also has more general information.

Consent required to export statistics
Following the implementation of GDPR compliance with BOINC, user consent is now required to export BOINC statistics from LHC@home to BOINC statistics sites, such as BOINC stats.

To grant your consent, please login to the LHC@home site and update your project preferences. Once logged on to the LHC@home site, please navigate to the Project Preferences page.

Click on "Edit preferences" and then tick the box on the line:
"Do you consent to exporting your data to BOINC statistics aggregation Web sites?"

This will enable continued export of statistics from LHC@home for your BOINC user account. If you leave the box unchecked, statistics should no longer be exported.

Thanks for your contributions to LHC@home!
