About ATLAS@Home
ATLAS@Home is a research project that uses volunteer computing to run simulations of the ATLAS experiment at CERN. You can participate by downloading and running a free program on your computer.

ATLAS is a particle physics experiment taking place at the Large Hadron Collider at CERN, that searches for new particles and processes using head-on collisions of protons of extraordinary high energy. Petabytes of data were recorded, processed and analyzed during the first three years of data taking, leading to up to 300 publications covering all the aspects of the Standard Model of particle physics, including the discovery of the Higgs boson in 2012.

Large scale simulation campaigns are a key ingredient for physicists, who permanently compare their data with both "known" physics and "new" phenomena predicted by alternative models of the universe, particles and interactions. This simulation runs on the WLCG Computing Grid and at any one point there are around 150,000 tasks running. You can help us run even more simulation by using your computer's idle time to run these same tasks.

No knowledge of particle physics is required, but for those interested in more details, at the moment we simulate the creation and decay of supersymmetric bosons and fermions, new types of particles that we would love to discover next year, as they would help us to shed light on the dark matter mystery!

The program you will download runs simulation software inside a virtual machine hosted by your computer. The virtual machine image is ~500MB but is only downloaded once. Each workunit downloads a small set of input data and runs for approx 1 to 2 hours depending on the computer's processor speed.

THE ATLAS@Home PROJECT IS STILL UNDER DEVELOPMENT, and it cannot be guaranteed that jobs will be free from errors or that there will always be work available, but do not hesitate to contact us at atlas.home@cern.ch



Join ATLAS@Home

Read our rules and policies
This project uses BOINC. If you're already running BOINC, select Add Project. If not, download BOINC.
This project also requires VirtualBox to be installed.
Windows: VirtualBox is included in Windows distributions of Boinc and so does not have to be installed separately.
Mac and Linux: VirtualBox must be installed separately
In case of problems using the latest version of VirtualBox try using version 4.2.16.
After choosing Add Project in Boinc Manager, choose ATLAS@home from the list of projects
Then either enter details for to set up a new account, or if you have previously registered enter the existing account details.
IMPORTANT:
A reasonably powerful modern 64-bit computer with at least 4GB of memory is required to run ATLAS@Home. Enabling 64-bit virtualisation may require some changes in BIOS settings.
In Boinc Manger set the % of processors used to be at most 50%, otherwise your computer may run out of memory.
The work units may use a lot of network bandwidth, so a slow internet connection may reduce work unit efficiency
If you're running a command-line version of BOINC, create an account first.
If you have any problems, get help here.
The best form of help from above is a sniper on the rooftop....

Not sure about joining through Boinc Manager whether it works or not. I joined through BamStas account manager and it gave me an error on connecting that the URL supplied was wrong.

Currently the URL to connect to is http://atlasathome.cern.ch/

Haven't received any units to comment on project yet as I currently only have access to a 32bit laptop and can't use Bam to connect project to any of my other systems until they sort the broken URL.

edit On a follow up from above, contacted project and hopefully the URL issues will be resolved soon.

BamStats issues fixed, works fine now.
Crunched some of these units with no problems. TSBT currently #5 in the UK just now ..... getting on it ....
