 The this layout connects 2 experiment on DETERLab.  This is because the testbeds are all prefixed with the {{{deter}}} testbed name.  The ''testbed''/''sub-testbed'' syntax allows multiple instantiations of experiments on the same testbed.  This layout creates 2 experiment on DETERLab (DETERLab's [NewFeddAbout#TheExperimentController experiment contoller] maps the {{{deter}}} testbed name to DETERLab).

-A user can certainly use the fedd_multistatus.py command to poll and monitor experiment creation, but output is fairly terse and polling is inefficient.  The {{{fedd_spewlog.py}}} command will output a debugging log from the experiment controller.  If the experiment is being created or terminated, the command puts out the log so far and continues updating it until the operation succeeds or fails.  A user can follow the progress of the creation in real time using this command.

 Similar work can be done to present unified login information and shared filesystems.  That is not done in this case because the experiments are both in the same DETER project and testbed.
 
+== Releasing Resources ==
+
+When the federated experiment is no longer needed, the [FeddCommands#fedd_terminate.py fedd_terminate.py] command is used to release resources.  Individual testbeds release resources and the experiment controller purges all its data.  To release the experiment above:

+{{{
