Using the latest BOSCO version, we can do direct submissions to the remote PBS|SGE cluster using SSH.

Here is a sample file.

bash-4.1$ more direct-bosco.sub
universe = grid
grid_resource = batch pbs vahi@br0.renci.org
output = /local-scratch/vahi/work/bosco/direct-ssh/direct-bosco.out
error = /local-scratch/vahi/work/bosco/direct-ssh/direct-bosco.err
transfer_executable=false
executable = /bin/hostname
#arguments = Hello
log = /local-scratch/vahi/work/bosco/direct-ssh/direct-bosco.log
notification = NEVER
