+In these runs, Swift was moving data to and from the data/ directory by
+staging to the compute node local (RAM) filesystem. For some workflows its
+better to bypass staging and access all input and output files directly.
+
+We do this by specifying a "data management rules" file on the command line
+and turning off staging to the local filesystem:
+
+  $ sed -i -e '/SET PROVIDER STAGING/s/=true/=false/p' $HOME/.swift/swift.properties

+Now run the script with "direct" data acces
