vLHCathome

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.

This is just the pure BOINC server application. Please visit the vLHC Background information 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.

Warning: do not upgrade beyond VirtualBox 4.3.12 !!
Due to several problems being reported with the latest version of VirtualBox (4.3.14), we strongly advise volunteers not to upgrade beyond VirtualBox 4.3.12.

Server migration completed
The migration of Test4Theory to the new vLHC@home server is completed. In case of problems, we advice to detach and re-attach to the project.

Thanks for your understanding and for your contributions!

Migration to new server and change of project name
On Monday July 14, the Test4theory project will be migrated to a new server, and also get a new name: "vLHC@home".

Following 3 years of running Theory simulations under CernVM and BOINC, we plan to gradually expand the project and add more applications on CernVM with simulations from the LHC experiments. Thus the new name: "Virtual LHC@home".

The old server URL will be redirected, and we expect that the transition should be transparent to BOINC clients. The forums and BOINC user database with accumulated credit will remain the same as today. There is a slight risk that running tasks may fail and that the credit for these will be lost. We would in that case recommend to detach and re-attach to the project. Further advice will be given here in the News forum once the upgrade is completed.

We would like to express our warmest thanks to all of you for your contributions to Test4Theory, and hope that you will continue to stay with us in the future!

Pleasse upgrade to BOINC 7.x clients
Most users of this project already use BOINC 7.x clients, however there still a few people who are using old BOINC 6.x clients and the old cernvm wrapper.

We plan to upgrade to a new server in the near future and to phase out the old wrapper, so please upgrade your BOINC clients to BOINC 7.x. The current version available is BOINC client 7.2.42, and most OS packages are available with a recent 7.2 version that will give better functionality and a better user experience.

Thanks for your contributions and your collaboration!

VM connection problem solved
The problem that started after midnight Geneva time this morning has now been solved.

Our support team was working from Rome, Geneva and Silicon Valley, and all on a Sunday. This is the spirit of Test4Theory and we thank everyone involved, and all our volunteers for their patience.
