to copy this workunit as needed to maintain a given supply of work.
<h3>Feeder</h3>
<p>
This program is supplied by BOINC and is application independent.
It creates a shared-memory segment used to pass database records
to CGI scheduler processes.
It has the command-line option:
<pre>
-mod n i
</pre>
If present, this instance of the feeder will handle
only workunits for which mod(id, n) = i.
This lets you run schedulers on arbitrarily many machines.
