# A shell script to start the main screen session on ANIM machines
# This can in theory run also on WARP (but please please only use PBS not this!)
# This works on the vision machines at CSAIL now
# hacked up by Tomasz Malisiewicz (tomasz@cmu.edu)
# Run like: ./sc.sh script_name
# The above command will run "script_name" on machine 8 through machine 10
