Why Do My Jobs Only Run On Submit Machine
HTCondor will only send jobs from a submit machine to a remote execute machine if it has been told that the two machines share a common file system, or if file transfer is enabled. If you have this problem, try setting the following lines in your submit file to enable file transfer: 

should_transfer_files = yes
when_to_transfer_output = on_exit
transfer_input_files = file_to_transfer1, another_file_to_transfer, and_so_on

Note that the executable is included by default in the file transfer list.
