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.
This is just a BOINC server. Please visit the LHC@home information for more information. If you have any problems or questions please visit the Message Boards, Questions and Answers and FAQ.

Task Tracker
I have added a task tracker to the top left of the page so everyone can see what issues we know about, which one are being worked on and what is being done right now. It still needs populating with a few items. 3 Aug 2016, 10:08:09 UTC · Comment


Task and CPU limiter
The server has just been updated to add the feature that limits Tasks and CPUs per user. This limit can be controlled in the project preferences.

Together with my changes to the scheduler, per-project limits on jobs in progress and #CPUs should now work. But I haven't actually tested this. Laurence, please try it and tell me if it doesn't work.

Update
David Anderson, Rom Walton and myself had a conference call yesterday where we discussed limiting tasks per user, why we want to do this, mutli-core VMs and the VT-x issues.

One of the reasons why we would like to limit tasks is that machines can be assigned more tasks that they can handle or is desired, which leads to problems. David pointed out that BOINC should respect the resource constraints and if not the issue needs to be looked into. Feedback on this would be welcome so I have created a new thread where you can paste any scenarios where BOINC is not respecting the constraints.

Implementing a task limit per user should be straight forward. I will provide an updated php file for the project preferences and David will update the scheduler code to take this into consideration.

Similarly for multi-core, we can set a flag in the project preference on whether or not you would like BOINC provide multi-core VMs. This is an area where we probably still need to experiment.

Finally, the VT-x issue was discussed as over 30% of our failed tasks are VMs that fail to boot due to this setting not being available or enabled. It was pointed out that tasks should not be provided if the machine is not capable of running them. This will also be investigated.

Scheduler and vbox update to detect 64-bit enabled computers
The BOINC scheduler has been updated to detect 64 bit machines that do not have the virtualization hardware extensions enabled. Also vboxwrapper has been updated for better error handling, and vboxwrapper 26193 is now deployed for Windows and Linux for the Theory application.

Many thanks to RomW for providing these changes!
