This section explains the steps you need to take in order to start contributing to scientific progress! For information on any of the projects, simply go to Projects. If you're not sure what the software does that you're downloading, see How It Works. If you have any other questions, look at the FAQ, or contact us!
All you need to do is install the appropriate software then attach BOINC to your desired project. Step-by-step videos are provided for each platform. Click on the operating system choices below for more information.
Step 1 -- Install BOINC
All of our LHC@Home applications use BOINC, which is available for download on the official BOINC site. BOINC will detect your running operating system, automatically choose the best client for your computer, and give you a link to download an installer package.
Note that while set-up is automatic, it does vary under the hood from one operating system to another. Before double-clicking in the installer, please check the following notes depending on your operating system:
Download the BOINC client installer from the official BOINC site, and follow the instructions without modifying the default options.
In GNU/Linux systems there are two possible ways of installing BOINC:
Using the distribution packaging system (apt-get, yum, conary, etc.), or
Using the self BOINC installer provided by the official BOINC team.
The first solution could be the easiest one, however, before installing it via this way, double check that the version that you are going to install is >= 7.0. If your distribution only has version 6, then, you should use the second method.
If you do not know which is the best method for you, we recommend you to use the second method.
Copy the appropriate URL into the pop-up window, then click "next", and follow the instructions.
You will be asked to provide a user name and password to create an account in our system. After creating the your account, your system will be ready to start receiving jobs from CERN.
Modify your BOINC preferences
For best performance of LHC@home projects, we recommend that you review your BOINC client preferences using your BOINC Manager as follows:
1. Under the Preferences Tab "processor usage", in the line "While processor usage is less than X percent (0 means no restriction)", you can at the beginning keep BOINC default for X is 25% which causes some pausing/resuming of the VirtualBox process. If you want to try to contribute a maximum, you can set the box X to 0 (zero).
2. Under "Use at most X % CPU time", set the box X to maximum 80 % in the beginning, to make sure that your machine does not get blocked. (The BOINC default used to be 60%, but is now 100% for some client versions.) You can later try to set the box X to 100 % if you wish to contribute a maximum.
3. On multiprocessor systems, you can chose to use only a subset of them and reduce the number of tasks running in parallel accordingly.
BOINC Network preferences to suspend and resume work should now work properly.
See How It Works for more information on the software you will be downloading. Everything is free to download and use.
All LHC@Home applications use an underlying software called BOINC.
Some of the applications also depend on virtualisation for which you will need VirtualBox.
See the information on the left for more instructions.
In order to be able to run 64bit Virtual Machines on your computer with Virtual Box, you need to enable hardware virtualization technology extensions (VT-x) in your PC BIOS if it is not already enabled.
The exact procedure to do this depends on your hardware. You can find more information on this link or search for VT-x (or amd-v) for your type of PC.
Note that you will need to have an open internet connection while running project tasks.
Tasks will not run if you are not connected to the internet!
