Participating in multiple projects

You can join a second and subsequent projects as follows.

  1. Visit the new project's web site and create an account. Note: if you wish, you can use different email, user name or password than those of your first account.
  2. Receive an email containing an account ID (a long random string).
  3. Visit the original project's web site and log in. Click on Edit Preferences. Click on Add Project. Enter the URL of the second project, and the new account ID.
  4. Enter resource shares for each of the projects.
This procedure adds the new project to your preferences, which will be propagated to all your hosts. There is no need to perform any manual operation on each host.

How preferences are stored

Your preferences are stored on BOINC servers. When your hosts communicate with a server they get the latest preferences, and they pass along these preferences to other servers. Thus, when you change your preferences on one project's web site, these changes will quickly spread to all your hosts, and to the web sites of all the other projects in which you participate.

If you change your preferences first at one project and then at another, the second changes will overwrite the first. To avoid this, do all your edits at one project.

Some projects may provide a web interface for editing their project-specific preferences. In this case it may be necessary to edit preferences at different sites. To avoid overwriting edits, wait until previous edits have propagated to a site before editing preferences there.
