Desktop Cloud Visualization (DCV)

DCV enables remote accessing OpenGL-3D-applications running on the server (taurus) using the server's GPUs.

Prerequisities:

  1. Have access to the vpn-gateway vpn-zih-hpc. You can make an application by email to hpcsupport@zih.tu-dresden.de (this might only be necessary when accessing from outside the campus network).
  2. Install DCV Viewer locally (only untar). You can download it from https://www.nice-software.com/download/nice-dcv-2016 or find a copy on Taurus under: /sw/taurus/tools/dcv

Execute:

  1. Establish a connection to the vpn-gateway vpn-zih-hpc.
  2. Log in to taurus.hrsk.tu-dresden.de
  3. Start interactive batch job on node taurusi2108 (that's the only node where DCV is installed):
    > srun --pty --time=1:00:00 --gres=gpu:1 -w taurusi2108 bash -l -i
    ... <wait for job allocation>
  4. Start vncserver in the interactive shell:
    > vncserver [-geometry width x height] (e.g vncserver -geometry 1910x1170 using a 1920x1200 display)
    --> answers:
    ...
    New desktop is taurusi2108:n (172.24.36.117:n)
    ("n" will be incremented over all vncservers running on the current node).
  5. On your local desktop PC, start niceviewer:
    1. Connect to 172.24.36.117:port (port is 5900 + the "n" from step 4, e.g. 5901 if n=1).
    2. Log in with your ZIH login
  6. Try it: Open a terminal in the gnome desktop and call "dcvtest", to check if it runs.
    Optionally you can open a console by Ctrl+Shift+F9 to adjust the quality (the default is very low).
    Start your OpenGL application...
