For running Swift locally on a Condor cluster, use a sites.xml based on 
this example:

<execution provider="condor" url="none" />

<config>

   <pool handle="localhost">
     <gridftp url="local://localhost" />
     <execution provider="local" url="none" />
     <workdirectory>/home/erin/swiftwork</workdirectory>
     <profile namespace="karajan" key="jobThrottle">.03</profile>
     <profile namespace="karajan" key="initialScore">10000</profile>
   </pool>

   <pool handle="condor">
     <execution provider="condor" url="none"/>
     <gridftp url="local://localhost"/>
     <workdirectory>/home/erin/swiftwork</workdirectory>
     <profile namespace="karajan" key="jobThrottle">.19</profile>
     <profile namespace="karajan" key="initialScore">10000</profile>
   </pool>

</config>

The jobThrottle values above will enable Swift to run up to 4 jobs at a 
time on localhost and 20 jobs at a time on the Condor cluster.

Use tc.data to catalog applications on pool or the other.

Set jobThrottle as desired to control execution parallelism.

#jobs run in parallel is (jobThrottle * 100)+1

initialScore=10000 overrides Swift's "start slow" approach to sensing 
the site's responsiveness.
