project_tao_osg_vep processes on all nodes and
restart velauncher.py.
Ensure that the correct IP addresses are listed on the Cluster Nodes dialog of VE-Launcher. Also ensure that the correct name is listed for the master (cavehead) in the MASTER field of the Cluster Nodes dialog.
I see the error message "Error: can't open display on device":
Issue the xhost + command on all the nodes of
the cluster. For example, from the command line type ssh
drone1, then type xhost + (Note the space
between xhost and +)
Ensure that you have read permissions on the graphics card
by typing ls -ltr /dev/nvidia*. If you do not have
read permissions, ask the system admininstrator to enable read
permissions.
I see the error message "Could not connect to the Name Server..."
Ensure that the correct IP address is listed on the CE name of the VE-Launcher dialog (currently 10.10.20.241)
