Projects export statistics data in XML-format files. Most projects regenerate the files every 24 hours. These files are contained in a directory DOWNLOAD_URL/stats/. For most projects, DOWNLOAD_URL is the project's master URL. However, some projects (notably IBM WCG) put them elsewhere; in these cases, the URL is given by the web_rpc_url_base element returned by the project's get_project_config.php web RPC.

The download directory contains the following files:

tables.xml:: This gives the total number of teams, users, and hosts. It also includes the UNIX time when the files were last generated, a list of the project's applications, and the list of badges defined by the project. For example:

<tables>
    <update_time>1046220857</update_time>
    [ <credit_by_app/> ]
    <nusers>127</nusers>
    <nteams>14</nteams>
    <nhosts>681</nhosts>
    <total_credit>1234.234</total_credit>
    <applications>
        <application>
            <name>setiathome</name>
            <results_unsent>100</results_unsent>
            <results_in_progress>1000</results_in_progress>
            <results_over>10000</results_over>
        </application>
        ...
    </applications>
    <badges>
       <badge>
           <id>10</id>
           <name>user_pct_2</name>
           <title>Top 25% in average credit</name>
           <image_url>img/pct_25.png</image_url>
       </badge>
	 ...
    </badges>
</tables>

host.gz:: List of hosts team.gz:: List of teams user.gz:: List of users badge_user.gz:: list of user badge assignments badge_team.gz:: list of team badge assignments

If the <credit_by_app/> flag is present in tables.xml, there will also be

user_work.gz:: user credit, broken down by app team_work.gz:: team credit, broken down by app

The format of the various XML elements in the output files is as follows. Notes:

  • <cpid> ('cross-project identifier') is a unique identifier across multiple projects. Accounts with the same email address on different projects will have the same cross-project identifier (as long as at least one computer is attached to both accounts).
  • All 'expavg_credit' values were computed at some point in the past (given by 'expavg_time'). To compute their current values, they must be scaled according to the RAC decay formula.
  • Text fields may contain XML entities. If you aren't using a real XML parser, you need to decode the entities yourself.

The following fields are of the form [x1|x2|...|xn]. Depending on the client version, only an initial subset of items may be present.

boinc_version:: The BOINC client version currently running on the host. The third item is the client "brand", such as "HTC Power to Give" or "Samsung Power Sleep".

vbox_version:: The version of VirtualBox installed on the client host.

coprocs:: A list of GPU descriptors. The items in each one are:

  • The manufacturer. "CUDA" means NVIDIA, "CAL" means AMD, and "INTEL" means Intel.
  • The model name.
  • The number of GPUs.
  • The amount of video RAM.
  • The driver version.
  • The OpenCL version; 102 means 1.2.
