Test4Theory

This is a project that utilizes the CERN-developed CernVM virtual machine and the BOINC virtualization layer to harness volunteer cloud computing power for full-fledged LHC event physics simulation on volunteer computers.

The theory simulations that have been running as Test4Theory since 2011, were the first of a series of physics applications running on the LHC@home platform. Soon the theory simulations will be followed by more simulations from the LHC experiment collaborations. These applications exploit virtual machine technology, enabling volunteers to contribute to the huge computational task of searching for new fundamental particles and physics at CERN's LHC.

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 Board, Questions and Answers and FAQ sections of the project.

3 TRILLION EVENTS REACHED BY TEST4THEORY TODAY !!!
Congratulations and thanks to all our volunteers for helping CERN to reach the extremely impressive total of 3 Trillion events successfully simulated on our Theory project.

We have recently received warm testimonials from scientists who use and appreciate the MCPlots database which is the destination of all your work. We have posted these on our "Science" message board at:

Please don't upgrade to Virtual Box 5.1.2 as it does not seem to work for us at the moment. An issue(#1606) has been submitted to the developers. 8 Aug 2016, 13:22:55 UTC · Comment


Server Upgrade
The server will be upgraded Monday morning. The downtime should be no longer than a few minutes. 29 Jul 2016, 12:00:57 UTC · Comment


Theory Tasks Available
Theory tasks are available again. The downtime was caused by a suspected NFS related problem that resulted in a bad batch of jobs. The submission code has been hardened to detect this scenario in the future. The maximum jobs in progress limit has been put back to 2 and we will consider increasing this limit in the very near future. 25 Jul 2016, 10:22:11 UTC · Comment


CMS Application Now Available
As the issues with the Theory application will probably not be fixed until after the weekend, the CMS application has been made available for everyone. Due to the slightly larger memory requirements, the the number of tasks that can be run simultaneously on a host has been reduced from 2 to 1. If for whatever reason you do not wish to run the CMS application, you can update your project specific preferences to run only the applications that you select. There will be no more tasks for Theory app until the problem has been resolved. 22 Jul 2016, 20:56:29 UTC · Comment
