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.

New native Linux ATLAS application
Hi all,

If you don't use Linux you can ignore the rest of this post. If you do you may be interested in trying the experimental ATLAS app which doesn't use virtualbox but runs natively on Linux.

IMPORTANT!! To run this app you must install CVMFS, the CERN VM File System, and configure it for ATLAS. This file system contains all the software for ATLAS WU and is normally inside the virtual image (the same as for all LHC vbox apps).

A simple installation guide can be found here: https://cernvm.cern.ch/portal/filesystem/quickstart

You should set up the repositories as shown in the example for ATLAS. If you have a squid proxy handy you can specify it there - if not I'm not sure whether it will work or not without configuring one.

Our target for this app is CERN or ATLAS-related institutes who have idle machines with CVMFS already installed, and we do not expect the average volunteer to install CVMFS and run this app. But I think all of you here are above-average volunteers :) and you may be interested in trying it.

Please give feedback on the ATLAS forums. Unfortunately there is no way to check for CVMFS on the client before requesting tasks, so if you don't have CVMFS you can still get these tasks and they will fail straight away. So better to uncheck the ATLAS app if you don't want to run it.

Draining the CMS job queue
Because of an upgrade to the WMAgent server, we need to drain the CMS job queue. So, I'm not submitting any more batches at present and we should start running out over the weekend. If you see that you are not getting any CMS jobs (not tasks...) please set No New Jobs or stop BOINC.
I expect that the intervention will take place Monday morning, and hopefully we'll have new jobs again later that day.

Good news for the CMS@Home application
We've now demonstrated that we can perform all the steps required to bring CMS@Home into a production tool for CMS Monte-Carlo data production. Please see this announcement at LHC@Home for more details. 27 Jan 2017, 21:03:51 UTC · Comment

SSL on lhcathomedev.cern.ch
We have now got a proper certificate for our DEV server, and use the opportunity to change name to: LHCathome-dev, so please use this URL from now on for the LHC@home-dev project:


The former test SSL URL to this project on the production server will be stopped and redirected here.

Thanks for your continued support and help!

CMS Servers up again

YEP Linux is just the greatest and most secure OS ever 😎

.....I didn't do it.......and I never liked a Dirty Cow

(OK I won't restart the OS war)
