You will need to add the following lines to the submit file (before the queue statement):
 {verbatim}
 +MayUseAWS = TRUE
-+WantFlocking = TRUE'
++WantFlocking = TRUE
 {endverbatim}
 A reminder: this means these jobs will flock!  For now, you shouldn't use =condor_annex= if you don't want your jobs flocking.
