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.

Vboxwrapper upgrade to latest version v261.66 (all systems)
We have just upgraded to vboxwrapper v261.66 for all BOINC T4T clients (Windows, Linux and Mac).

Please let us know if any problems occur, preferably by posting to this News thread.

Note that starting with this release snapshots will no longer be used: VM's will be Saved rather than PoweredOff when BOINC suspends or restarts, which avoids losing or repeating some jobs or events.

Problem with CERN server resolved
Well, in spite of it being Easter Saturday, the support team did identify the failing server machine and the problem is fixed. Particular thanks to Pete Jones (in Geneva) and Artem Harutyunyan (in California !!).

Happy holidays again to all.

Problem with CERN server
Since 8pm yesterday there is a problem with part of the CERN server infrastructure for vLHC@home, which prevents jobs being fetched or returned to the VM's. As CERN is closed for the Easter holidays, this may not get resolved until Tuesday April 7th. In any case we wish all our volunteers a happy holiday break!

Vboxwrapper upgrade to latest version v261.57 (all systems)
We have just upgraded to vboxwrapper v261.57 for all BOINC T4T clients (Windows, Linux and Mac).

Please let us know if any problems occur, preferably by posting to this News thread.

When all this is running well, it will allow us finally to lift the restriction to VirtualBox version 4.3.12 that we have had to live with since last summer, particularly for Windows clients. We will make a separate announcement when this is decided.

Vboxwrapper upgrade to latest version v261.55 (Windows only)
We have just upgraded to vboxwrapper v261.55 for BOINC T4T clients running Windows.

Please let us know if any problems occur, preferably by posting to this News thread.

We will upgrade vboxwrapper for Linux and MacOSX clients later.

When all this is running well, it will allow us finally to lift the restriction to VirtualBox version 4.3.12 that we have had to live with since last summer, particularly for Windows clients. We will make a separate announcement when this is decided.
