===== Interactive node access via VNC ======

To make use of a compute node for visualization - since long running jobs are not allowed on the login nodes - you need to perform the following steps on the login nodes of VSC-3.

  module load TurboVNC

**Only once**: Set a vnc password. This is needed when connecting to the vnc server.

  mkdir ${HOME}/.vnc
  vncpasswd
  Password: ******
  Warning: password truncated to the length of 8.
  Verify:   ******
  Would you like to enter a view-only password (y/n)? n

On the login node allocate a compute node (wait for the next available node) and start the vnc in the slurm context:

  salloc -N 1 [-L <licence> -J <jobname> ..]
  srun vnc.py

Follow the instructions on the screen and connect from your local machine with a vncviewer:

  vncviewer -via <user>@vsc3.vsc.ac.at <node>::<port>
