BOINC FAQ

Warning, important This is a work in progress. Comments are most welcome!

What ressources will BOINC use on my computer ?

The virtual machine will use only one core. How exactly can be set in the BOINC computing preferences ( Tools > Computing Preferences). Mainly :

  • While processor usage is less than X percent (default 25) will set the minimum processor user under which BOINC will start
  • Use at most X% CPU time (default 100)
Memory and network usage can also be configured.

What informations about me and my computer are sent to you ?

Your account name and country will appears on the public leaderboards on the project web site. Your e-mail address is accessible only to the project administrators.

When you attach a computer to the project, it will be attributed an unique ID (know as host ID or computer ID) and associated to your account.

Do I have to do something special to shutdown or restart my computer ?

No, BOINC will take care of stopping the task.

If you want to temporary disable BOINC computation, you can do so by setting Activity > Suspend (and Run based on preferences to re-enable it).

What is my Computer ID ?

BOINC will attach an ID number to each computer you connect to the project.

To see what is your ID, go to Project Commands > Properties. The ID is under the label Computer ID.

Can I see the VM in VirtualBox Manager ?

Maybe. On some Linux distributions and OS X, BOINC is running under its own user so if you launch VirtualBox Manager as your everyday user you may not see the BOINC VM, depending on how permissions are set up. Unfortunatly there is no definitive awnser.

Can I see what is happening inside the VM ?

Yes. BOINC will enable a remote desktop server on the VM if possible. For that you will need the VirtualBox Extension Pack.

It must be installed before the VM starts. If that's not the case, restart a VM : Task Commands > Abort.

Go then to advance view ( View > Advance View) and the Tasks tab. Select the Beauty@LHC task. A Show VM console button should be in the left column, that will open a rdesktop session to the VM. OS X users will need to install the CoRD remote desktop client.

If this button does not works, you can connect using a remote desktop client (eg. rdesktop on Linux) to localhost, and the port given on the VM entry in VirtualBox Manager.

Once you get to the VM console, you can login and sudo as boinc, password boinc.

[Linux] BOINC can't connect to the VM hypervisor

This may be caused by a VirtualBox update during which the kernel virtualization module was not properly updated.

This command will update it :

$ sudo /etc/init.d/vboxdrv setup
