+<h2>Desktop grid versus volunteer computing</h2>
+<p>
+<b>Desktop grid computing</b>
+is a form of distributed computing in which
+an organization (such as a business)
+uses its existing desktop PCs to handle long-running computational tasks.
+This differs from volunteer computing in several ways:
+<ul>
+<li> The computing resources can be trusted;
+i.e. one can assume that the PCs don't return results that are
+wrong either intentionally or due to hardware malfunction,
+and that they don't falsify credit.
+Hence there is typically no need for redundant computing.
+<li> There is no need for screensaver graphics;
+in fact it may be desirable to have the computation
+be completely invisible and out of the control of the PC user.
+<li> Client deployment is typically automated.
+</ul>
+
+<h2>BOINC as a desktop grid computing platform</h2>
+<p>
+Although it was originally designed for volunteer computing,
+BOINC works very well for desktop grid computing.
+The steps in creating a desktop grid are:
+<ul>
+<li>
+<a href=create_project.php>Set up a BOINC server</a>,
+develop or port applications, and test them.
+Set <a href=work.php>workunit parameters</a> to disable redundancy.
+<li>
+Create an account with the <a href=prefs.php>general preferences</a>
+that you want enforced on your desktop grid.
+<li>
+<a href=project_options.php>Configure your project</a>
+to disable account creation.
+<li>
+<a href=win_deploy.php>Create a custom installer</a>
+that includes the desired
+<a href=client_unix.php>configuration files</a>.
+Typically, this would include an account file
+that would attach each client to the account on your project.
+You might also want to include files that allow
+clients to be remotely monitored and controlled.
+
+<li>
+Deploy your installer; on Windows networks
+this can be done using <a href=win_deploy.php>Active Directories</a>.
+</ul>
+
+<p>
+To ensure that outside PC can't participate in your project
+or access its files,
+configure your firewall to prevent HTTP access to your BOINC server.
