# paraview client on remote workstation launches an xterm which
# ssh reverse-tunnels into login node and executes this script.
# This script accepts args from ssh, starts ncat listening for 
# a connection from a MOM node and submits a job. 
#
# The job is created with a combination command line/job script file,
# so that the MOM node can supply some networking information to
# the compute node.
# 
# The end result is that the network traffic is ncat'd from compute node
# to mom node to login and back to the workstation.

#set -x

# Grab args passed over tunnel. The exported ones are used by the
# qsub script. The non-exported are used by the qsub command line.
