Visualization on JURECA

JURECA Visualization Nodes

All JURECA login nodes are equipped with GPUs for visualization purposes. There are no dedicated visualization login or batch nodes.

Here is an overview about the configuration:

12 login nodes:

  • ssh access via (see Access)

  • 1 TB main memory, 2 NVIDIA Quadro RTX8000

  • login nodes, that means direct access via ssh possible

  • shared by all users logged in

How to Use the Visualization Nodes

A graphical login simplifies the access to remote visualization and the data stored on the file system. Hence, we support and recommend the use of Virtual Network Computing (VNC) on the visualization nodes of JURECA. VNC provides a complete graphical and remote desktop by

  • transmitting the keyboard and mouse events from your computer to the remote machine and

  • relaying the graphical screen updates back in the other direction.

VNC is

  • platform-independent (VNC viewers are available for almost any operating system)

  • application-independent (no need for remote visualization support inside the application)

With the help of VirtualGL installed on JURECA vis nodes OpenGL commands of visualization software can be processed on their local GPUs. In contrast to X-forwarding (ssh -X) this can speed up visualization tremendously especially for large data sets.
