<h2>Scheduling/resource management</h2>
<h4>* Summary:</h4>
<p>
An internal module of the
<a href="../faq.html#workspace-service">workspace service</a>
that governs <i>when</i> and <i>where</i> the VMs will run.
</p>
<p>
An active implementation is <b>required</b>.
</p>
<hr />
<h4>* Java interface:</h4>
<p>
<b>org.globus.workspace.scheduler.Scheduler</b>
</p>
<p>
Source code: <i>service/service/java/source/src/org/globus/workspace/scheduler/</i>
</p>
<p>
Activated by way of the <i>$GLOBUS_LOCATION/etc/nimbus/workspace-service/other/main.xml</i>
file -- see the "nimbus-rm.scheduler.Scheduler" Spring bean.
</p>
<hr />
<h4>* Default implementation:</h4>
<p>
<b>org.globus.workspace.scheduler.defaults.DefaultSchedulerAdapter</b>
</p>
<p>
Source code: <i>service/service/java/source/src/org/globus/workspace/scheduler/defaults/</i>
</p>
<hr />
<h4>* Subcomponents:</h4>
<p>
The default Scheduler implementation has its own plugin interface called
<b>SlotManagement</b> (see <i>org.globus.workspace.scheduler.defaults.SlotManagement</i>)
in order to accomodate sharing its base functions but specializing one
aspect of it.
</p>
<p>
Replacement of the <b>SlotManagement</b> implementation is how the
<a href="../admin/reference.html#resource-pool-and-pilot">resource pool and
pilot</a> plugins are enabled and disabled. See these files:
<i>$GLOBUS_LOCATION/etc/nimbus/workspace-service/other/resource-locator*</i>
